PVC (or polyvinyl chloride) pipework is now widely use in many industries, from residential plumbing to very complicated and technical water treatment systems. Due to the material properties of plastic (PVC) pipes, they are really valuable for their thermo-resistant structure, fire retardant fabric, and also as a high quality water conduit. Leyton Plumbers work with plastic pipework.These plastic pipes are far superior to most other modern materials as they are environmentally friendly, and have chemical resistance, inherent toughness, heat resistance, and are also electrically non-conductive and do not corrode. Joints for this type of material are called the push-fit ‘O’ ring type of joint, as they are a quick means of connecting pipework. These joints can be pulled apart quite easily. They have fittings with a small ‘O’ ring fitted in a groove which double seals the joint and grips and holds the pipe. Now, the best advantage of this type of pipework is the weight which is almost nothing, there is also the ease of marking, cutting and jointing of the plastic. Athough the modern plastic pipes of today are very lightweight and easily cut for plumbing jobs, it does not mean that they are not strong enough to be fitted in a system like a domestic central heating system, in fact they are very strong and reliable. A Leyton Plumber carries and uses push fit fittings. PVC pipework can also be used to supply hot and cold water to taps around the home. Plastic pipework will safely connect to other metal pipes such as, steel, copper and even lead pipes without any kind of reaction. Plastic piping can resist frost better than metal pipes. There is a huge choice of plastic pipework available. The size of these pipes is taken from their outside diameter. The size of the pipes that carry the mains supply to a property underground are 15-22mm and 28mm. Pipes for overflows on storage tanks and toilets are 21mm in diameter. Waste water discharge pipes from wash basins basin are normally 32mm. Soil pipework that runs out to the sewer is usually 110mm in diameter.
