Follow these steps for successful installation. Before you get to work make sure youve selected the correct size and type of pipe, fittings, and solvent. Put all the materials and tools in a well-ventilated work area because solvent cement releases harmful vapors. Fittings should be matched after the pipes have been cut in order to make sure they connect perfectly. Once the pieces are cemented they are permanent, any mistake leads to a pipe being cut so align them well beforehand. The distance between the faces of the fittings should be measured. Also measure the depth of fitting holes and add to the first measurement. This makes the total length. Flexible plastic tubing - commonly made of polyurethane materials - are great for cold water plumbing use and uses whereas polybutelyne materials are the preferred choices by plumbing professionals for hot water piping . This is especially the case when it comes to hot water pipes leading from or even adjacent to hot water heaters -both gas and electric. If you use a clamping arrangement to attach an insert fitting , as opposed to bonding cements, then take good care and attention to tighten the 2 clamps fully with a screwdriver of your choice and preference. Smokey the bear says fire prevention is always best and highly preferable. Highly trained and certified professional plumbers will advise you that even at lower temperature on the scale , rigid plastic pipe and pipes carrying hot water become slightly flexible . Hence these pipes should be supported with clamps every 3 feet approximately and as well allowed some wriggle room: To attach an insert fitting simply join the two by a good rigid insert fitting along with two small clamps. The procedure is to simply slip a clamp in a loose fitting arrangement approx one half of an inch for each of the two pipes being fitted or joined together.
There two major types of plastic pipe: the rigid and flexible forms. Depending on the type of plastic it is made of, rigid or firm pipes are used for hot and cold water systems. In order to cut rigid pipes, a hack saw can be used. Solvent cement can easily glue pieces together. A tube cutter that is used for flexible copper pipe is convenient for cutting rigid style plastic pipes. However a specialized blade is demanded - one that is meant for chopping plastic not cast iron or bronze metal.
Flexible plastic pipe use is limited only to supply systems. Compression fittings are used to connect them instead of solvent cements. Generally, they are used for interior systems for hot and cold water. Plastic pipe can also be used for exterior water supply systems. Polybutylene can withstand high temperatures, is sturdy and slightly more expensive than the rigid pipe. In remodeling jobs, flexible pipe is preferred for passing through lawn irrigation system, floor, walls, and ceilings. These pipes are strong theres a chance they might be damaged so dont bend on sharp curves. Extra support ensures more stability in long runs.
