How to Install a Corner Shower on Top of a Tile Floor

You can have a tray design with a fully enclosed shower cabin cubicle or a corner bath with side panels and a shower screen. You can install both on top of a tiled floor. It is best to choose a shower with adjustable legs so it simply sits on top of the tiles. It is up to you whether or not to keep the pipework running to the shower head showing above the tiles, or have it installed inside the wall, before the tiles are laid. If you have had fresh tiling and do not wish to take the tiles back off the wall, select attractive stainless steel pipes and make a feature out of them.

1.Ensure your floor is structurally sound and that the tiles have had enough time to "cure" (harden and fix) into place. A full day since grouting should be sufficient. Lay your shower tray into position. Mark your chosen location for the waste water pipe using a black marker pen.

2.Fit the steam shower tray on top of the tiles and flush to the wall. Press it gently at each corner, adjusting the legs as you go so it begins to balance. Measure the balance with a spirit level. Try to keep the tray as low to the floor as possible. Reach inside the cavity of the tray and screw the trap to the waste outlet. Support the center of the tray using pieces of ply board or cement board.

3.Apply sealant or tile adhesive to the base of a non-adjustable shower tray using a sealant gun or trowel, respectively. This is not an ideal solution, but is the only way to bed a non-adjustable shower onto completed tile work. Press the shower into place firmly and leave to set for a day or two.

4.Apply bathroom grade silicone sealant around the edges of the new shower using a sealant gun. Pay particular attention to where the tray meets the walls. Smooth lumps out with your thumb. Wash excess off with warm, soapy water and a sponge.

5.Fix the shower steam to the stud wall if you do not have a fully enclosed cubicle. Make a plan showing the position of the pipes running from the shower tap and shower head. Run pipework across the tiles but behind the shower side panels. Use 15 mm. diameter pipes. Turn off the water at the mains before plumbing the pipes in. Waterproof the piping using a waterproof coating such as chrome casings or waterproof plastic casings that fit around 15-mm pipes.

6.Fit isolating valves to the ends of the pipes to ensure the water does not escape. Apply PTFE (polytetrafluoroethylene) tape around new joints to create waterproof seals. Use a female screw thread adaptor to connect the pipes to the Shower Room controls. Mount the controls beside the pipes on the wall. Silicone sealant seal the edges carefully before reconnecting the water supply.

Honda three wheel motorcycle Tech Tips

Honda’s Cub Series has been in production for over fifty years. The easy-to-ride, nearly unbreakable Cub and Super three wheel motorcycle have provided practical mobility to over 60 million people, making it the most popular motorcycle ever built. Reliability is among the Cubs greatest virtues. Three-time World Champion road racer, Kenny Roberts said, "They were bulletproof." That’s good news for Honda Cub mechanics. This is not a quirky bike. They seldom need anything more than a tune-up.

Motorcycles tend to be seasonal vehicles. Long periods of sitting have predictable affects on any engine and are exaggerated on small engines. For it’s amazing reputation, the three wheel motorcycle is not immune to fuel problems. Allowing fuel to sit in the Cub’s gas tank and the float-bowl of the carburetor can cause the carburetor to get gummed up. Or if the fuel evaporates, it can leave a lacquer-like residue. If your Cub won’t run and it’s been sitting for several months or more, you may need to clean and rebuild the carburetor with a a rebuild kit. Rebuild kits are readily available.

Another common problem encountered by the cargo tricycle is air restriction. To run, your Cub has to have the right ratio of fuel and air. If your carburetor is working properly, your problem is probably air or spark. The fix here is easy. Get a new air filter. If you ride on a dirt road and anywhere that will expose the engine to dirt and dust it will need to be replaced more often. Some Cub owners replace their filter with a higher flow permanent filter which only needs to be cleaned, never replaced.

The Cub’s ignition system is about as simple as they come. You’re not likely to have problems with anything but the battery which is always prone to being drained or dying altogether. If you don’t ride your Cub regularly, it is especially hard on the battery. The best thing you can do is buy a "smart charger"---a kind of trickle charger that will top off the battery, then stop charging when the battery is fully charged. You can attache a lead from your battery terminals and hang the lead out from under the seat so it is easy to plug in and unplug. This is one of the best things you can get for any Cub that is ridden any less than daily.

When people think Cub, the older Classic Cubs come to mind. Old or new, passenger tricycle electrics are particularly prone to damage from the elements. Electrical connections can oxidize over time. Vibrations can wear through electrical insulation, causing short circuits. While connectors are easy to clean with some solvent and fine steel wool, if your Cub’s electrical components look worse for the wear, consider replacing rather than repairing them. The engine will last almost indefinitely. If you replace your electrical components when they act up, your Cub may last indefinitely too.

LED structure and the light-emitting principle

The LED light-emitting diode, is a solid state semiconductor devices, which can be converted directly into electricity for light. The heart of the LED is a semiconductor wafer, light emitting diodes
One end of the chip attached to a bracket, one end is negative, the other end to connect the positive power supply, so that the entire chip to be epoxy encapsulated. The semiconductor chip consists of two parts, the part of the P-type semiconductor, the dominant hole in it, the other end of the N-type semiconductor, here is mainly electronic. But when two semiconductor connected to form a PN junction between them. When the current through the wire to the chip, the electrons would be pushed to the P region in the P region electron-hole recombination, and then will be issued in the form of photon energy, which is the principle of led tube. The wavelength of light is the color of light is determined by the material to form a PN junction. The initial LED as the light of the instructions of the instrumentation, then a variety of light-colored LEDs in traffic lights and a large area display a wide range of applications, resulting in a good economic and social benefits. To 12 inches of red traffic lights, for example, in the United States was long-lived, low-efficiency 140-watt incandescent lamp as a light source, it produces 2000 lumens of white light. The red filter, the light loss of 90%, leaving only 200 lumens of red light. In the light of the new design, Lumileds uses 18 red RGB LED light source, including circuit losses, the total power consumption of 14 watts to produce the same luminous efficiency. The car lights are also an important area of ??the LED light source applications.
For general lighting, people need a white light source. 1998 white light LED development. The LED is packaged together to make the GaN chip and yttrium aluminum garnet (YAG). GaN chip of blue (λp = 465nm yellow light shot Wd = 30nm), high-temperature sintering of YAG phosphors with Ce3 + by blue excitation peak 550nm. Blue Spot Light substrate is installed in the reflective cavity bowl, covered with a mixture of YAG thin layer of resin, about 200-500nm. led light issued by the blue part was absorbed by the phosphor, another part of the Blu-ray phosphors emit yellow mixed, can be too white. InGaN / YAG white[ LED tube>http://www.top-led-china.com/] by changing the YAG phosphor chemical composition and to adjust the thickness of the phosphor layer can be colored white color temperature 3500-10000K. This blue LED is white, simple structure, low cost, mature technology and high, so the use of up to
60s of last century, scientists use light-emitting principle of semiconductor PN junction, development became a LED light diodes. The development of the LED diode, the materials used GaASP its luminous color is red. After nearly 30 years of development, and now very familiar with the LED, can emit red, orange, yellow, green, blue shade. However, the white light LED lighting required only developed in recent years to introduce readers to the lighting, white LED.

What causes the high price of LED lights?

As a revolutionary green energy-saving lamps, LED energy-saving lamps, changing the previous energy-saving lamps contain heavy metal toxins, pollution problems, and much longer service life characteristics of the next generation of mainstream lighting products, but more expensive, few people interested.
In our view, the same power, namely, the wattage is the same energy-efficient light than ordinary energy-saving lamps brighter. In theory, the ordinary energy-saving lamp life of approximately 5000 hours, indoor LED lamp life of up to 50,000 hours. In theory, the calculation of electricity per day 5 hours, it’s life up to 27 years.
Normal wear and tear and glow the same premise, can choose the ordinary energy-saving in straight fluorescent lamps (15W) and equal to its glow LED lamps (9W). At present, an energy-saving lamps sell for about 50 yuan, the LED lamp is priced at 200 yuan. 50,000 hours of work time and residents of Harbin City, electricity (0.51 yuan / kWh) calculated the electricity of ordinary energy-saving lamps to 382.5 yuan (15 watts x 50000 hours) / 1000 × 0.51 = 382.5; the LED lights with The power cost of 229.5 yuan (9 watts x 50,000 hours) / 1000 × 0.51 = 229.5. In 50,000 hours of testing, however, ordinary energy-saving lamps, 10 lamps need to be replaced. Assume that a $ 50 general energy-saving lamps, including lamps fee of 25 yuan and 25 yuan lamp fee, then ignited the 50,000 hours cost $ 275 (25 × 10 tube +25 $ = 275); and lit 50,000 hours LED light only need one, cost about 200 yuan. Ordinary energy-saving lamps lit simultaneously by 50,000 hours, spent 657.5 yuan, LED lights, compared with 429.5 yuan. Seen in this light, an LED light than ordinary energy-saving lamps save 228 yuan. Each room lights total, the cost of the savings will be doubled.
What causes the high price of LED lights? Some three points:
Cooling and reasonable cost of design
Would account for about 20 percent in the structural design of the lighting in industrious people will have been priced very low, 20% of the cost very reasonable, the biggest problem is how to be more innovative, the design is more reasonable.
Cooling costs to be maintained at 5%, the actual thermal design is very simple and protect the two directions: First, the led tube and the external heat sink paths as short as possible, the shorter the better your thermal design; heat resistance is sufficient heat reached the path must also have the ’cooling-road’. this part of the cost structure is not much used in cooling costs.
Core technology is the high cost of
led industry upstream of most of the core patent is in foreign hands, we do not grasp the core technology, although the manufacturing capacity of[ LED flexible strip>http://www.led999.net/] application products accounted for 50% of the global share to 50 percent, but the profit is indeed one of the lowest .
LED chip with the process, increase in the number of larger wafer production process, will continue to reduce costs, reduce the rate of 20% annually in recent years, the price factor of the LED chip to light efficiency enhancement also included in the price reduction the same price to buy a better product. The cost of LED lighting in the LED chip, chip price down of led flood light Price dropped of at this stage of energy-saving lamps, interior lighting, natural everywhere. LED chip is still a great room for price cuts.
Power cost is seriously lagging behind
The power LED lighting is the weakest link, is seriously lagging behind the development of led lamps, quality needs to be improved. Design accounted for about 20% of the cost of lamps, some as high. As the technology development of power in about 5-10% of the most reasonable.
LED costs are high compared with other light, as in the 1990s before the invention of blue LED tube the LED Downlight industry, leading to the white LED can be achieved, in fact, now the cost is not high. LED environmental protection, energy saving, no mercury, and every quarter of the price of LED lamps are sliding down, I believe we can achieve the acceptable level within a short period of time.

LED lighting system to add the Old Bridge

Recently, GE Lighting, several sets of new LED Street Light in New Zealand for the local has a long history of Wang Jia Nuyi bridge upgrade traditional lighting systems. Wang Jia Nuyi River is the third largest river in New Zealand has a special significance in Maori culture, and Wang Jia Nuyi Bridge is the only one of several road and bridge rivers.
In order to improve the lighting conditions in Wang Jia Nuyi bridge main road, the City Council began to try to replace the traditional lighting technology, with different LED light source aimed at the application of energy-saving program. The new road lighting solution must maintain the same brightness as with conventional light sources have to meet the requirements of energy efficiency savings. Local lighting design company in New Zealand EvolveNZ GE Lighting of the 80WR150LED products.
Today, Wang Jia Nuyi Bridge on 14 sets of new GE LED lamps at night is a new look, this reform, Wang Jia Nuyi City Council to save up to NZ $ 9,000 (RMB46, 620), electricity and maintenance costs.
Compared with traditional sodium lamp Wang Jia Nuyi bridge before, GE LED product advantages:
Energy saving: from 165W to 80W
Each LED lamp is only 80 watts of power (less than a home, the power of 100 watt light bulb). Than the original use of sodium lamps saving 52% energy consumption. New lighting direct rays of light area, while the glare reduced to below 5%. Therefore, the use of new lighting products will not cause the top of the leaked, thereby reducing waste.
(2) reduce maintenance time
led flood light life is more permanent than the sodium lamp can last 12-15 years. At the same time period, the sodium lamp fittings may need to be replaced 3-4 times.
(3) to improve the light output
LED to generate white light makes night driving more comfortable; real light color effect, so that the drive line of sight is clearer. In addition, improved color security cameras better play efficacy.
Mr. EvolveNZ company general manager JohnBirks said: "The lighting configuration to restore the natural light to bring a more secure feeling and a white Spot Light makes the space more modern and dynamic sense of the night, can more clearly see the real life environment We hope that this lighting technology to attract more people to travel, to experience the night scenery of their host cities. "
Wang Jia Nuyi City Council infrastructure and assets Chairman of the Committee RayStevens said: "The new alternative can bring many potential advantages and benefits to the public, no doubt, members of the public will notice the new LED Tube to generate white light, rather than issued by the installation of sodium orange light. Wang Jia Nuyi City Council will gradually adopt the LED light source instead of the traditional lighting products, until completely replace it. "

How to Make Solar Hot Water?

Building a solar hot water heater can immediately reduce energy costs and can be utilized in any climate. "On average, if you install a solar panel water heater, your water heating bills should drop 50%--80%". However, it is important to note that it is necessary to have a backup hot water system for those cloudy days or periods of higher use.

1.Find a south facing slope, where sunlight will hit more than other areas. Preferably, you will also want the solar hot water heater to be close to the traditional water heater, thus eliminating some of the heat loss from warm water running through a labyrinthian network of pipes. This south-facing slope will be the home of your new solar hot water heater. Placement and orientation can be the "single most important" factors to consider when constructing a solar water heater.

2.Clean your extra hot water tank with a wire brush and paint it black. Prepare the tank by making sure that you have the correct fittings to run the water from the tank to the rest of the water heating system. Ensure that if you are placing the pv module water heater at an angle for maximum coverage by the sun, and that the cold water inlet is still at the bottom of the tank.

3.Construct the box. The size of the box should allow for the glass front to cover 1 square foot for every 2 to 2.5 gallons of water. This will ensure that you will have a large enough size for adequate solar gain. A standard patio door replacement glass (34 inches X 76 inches) is ideal for a 40 gal. water heater (Resources 3). Obviously, the box should also be big enough to fit the tank.

4.Place the tank into the plywood box and insulate the plywood box further by utilizing double-paned windows or multiple layers of close so that the trapped air will add as an extra measure of insulation. Using silicone to caulk the plywood box will also help seal-in the heat as well as keep unwanted moisture from the outside environment from getting inside. Finish preparing the box by drilling holes for pipes and installing insulation.

5.Connect solar module water heater to the traditional water heater already being utilized in your home. Place two bypass valves leading from the cold water supply to the solar water heater and the traditional water heater so that you can regulate which heating system the cold water flows to. Run piping from the hot water outlet on the solar water heater to the cold water inlet on your traditional heater so that the hot water is running into your existing water heater already hot.

How to Make Solar Water Heaters?

Solar water heater can reduce or eliminate the need for "grid" energy to heat water in the home. A panel in a window collects solar panel energy, heating water in pipes that is pumped back into the house for use. The average homeowner can build and install a solar hot water heater in about two hours.

Attach the four 2-by-4 boards to the edge of a sheet of plywood with wood screws, creating a shallow box. The length of the 2-by-4 boards and size of the plywood is dependent on the size of the window frame. Typically the plywood is 3 feet by 4 feet.

Drill two holes in opposite corners of the box, into the side of the 2-by-4s. These holes are the input and output for the water pipes, so they need to be slightly larger than the pipe diameter solar collector.Run a section of copper pipe through one of the holes, then across to the opposite side of the box.

Attach a 90-degree pipe fitting to the end of the pipe inside the box, then attach a smaller section of pipe to the end of the fitting. Secure another 90-degree fitting to the end of the small section to make a 180-degree turn in the pipe.

The beauty of a water heater pv module hot water system is that it does not have an electric bill. It can be used to transfer heat to the inside of a hothouse (a heated green house) or to heat water for other purposes.

Attach a long section of pipe to the last fitting, running it to the opposite side of the box.Repeat Steps 4 and 5 until the box is filled with a continuous length of copper pipe, ending at the second hole.Apply black paint to the interior of the box and the pipes. Two coats are recommended. The paint should not contain gloss. Allow the paint to dry.Cut a sheet of Plexiglas to fit the top of the box, then attach it with strong adhesive or screws. This seals the panel.

Mount the panel with L-brackets and screws in an area that gets lots of sunlight, preferably facing south. Connect the panel's pipes to the solar module air conditioner system with copper pipe couplers; the "top" pipe on the panel should be the input and have gravity help with the pumping, but it is not critical for operation. As sunlight enters the Plexiglas it is trapped and absorbed by the black pipes, which heat the water passing through them.

Straighten the hangers out. At one free edge of the sides of the bag, roll plastic over a hanger a few times. Poke a small hole in the plastic by the hanger at increments of 2 inches. Use the zip ties to strap the hanger to the mesh so that the hanger reinforces the edge of the bag. Do the same on the other side. Fill in gaps with spray foam.

Drill holes just big enough for the tubes to slide into the 5-gallon bucket. One hole should be drilled just below the top of the Solar Water Heater cell line, and the other should be drilled low in the bucket. Use Gorilla PVC glue to seal around the tubing. Use the rest of the foam sheet you cut earlier to insulate the bucket by gluing it on.
