The plumbing market place is full of many different kinds of plastic pipework. A Willesden Plumber uses these and other joints every day.The size of the pipe is dictated by its outside diameter. Water supply pipework that is running through a property or underground use the following sizes: 15mm, 22mm and 28mm.Pipework that will carry waste for example (overflow pipes, wash basins, bath, shower and sink waste water pipes, soil pipes) is again available in various sizes. Overflows from toilets and various tanks and cylinders use 21mm pipe, with things like wash basin waste water pipes generally being 32mm in diameter, and baths and sinks with 40 mm pipes. The soil pipes running from toilets have a diameter of 110mm. These pipes are really quite straightforward to cut, connect and fit. Willesden Plumbers are a professional service that fits all types of pipes and joints.Advantages:Pipes that are made from plastic are as flexible as they are lightweight and very easy to cut and work with. If you have the correct grade of plastic pipe, they can be used for the plumbing in a central heating system, even for a taps hot water supply. Plastic is a lot more frost resistant than metal, and as pipes, tend to creak less when they expand if fitted under a floor. There are no corrosion worries and they are easy to connect to copper, steel or lead pipes, with no risk of adverse metal reaction causing accelerated corrosion (if, for example, you connected a galvanized steel pipe to one made of copper).Common Joint:There is a joint called a push fit ‘O’ ring joints that is used by plumbers which is a fast way of connection. They can pull apart easy and are more cumbersome than a welded joint. These fittings have an internal ‘O’ ring fitted in a groove which makes a double seal and grips the pipe.
