There are a number of different types of pipes that are found in the home. Some of the most common are outlined below.
1-PEX (cross-linked polyethylene) is a highly durable plastic piping that is regularly used to carry water. PEX is rigid enough to cope with the pressures of water supply but sufficiently flexible to be able to weave through tight spaces. It is also much cheaper than many other piping materials, notably copper.
Polyvinyl chloride (PVC ) pipes are an excellent choice for drain/waste and vent lines. They are usually white in colour and are popular because of their low cost, flexibility, and the fact that they are lighter than traditional metal pipes. They are also fairly durable, easy to install, and can be joined using specialist adhesive.
3-Rigid copper pipes
Rigid copper pipes are a popular choice because they are durable, do not leach chemicals (unlike some plastic options), and can be cut easily using either a tubing cutter or hacksaw. However, they are more expensive than some other options.
There are a wide range of copper pipe fittings available for almost any application. These provide durable and long-lasting connections. If you are looking for some connection solutions, there are plenty of online resources available to help you find the best option such as the examples seen here watkinspowis.co.uk/products/copper-pipe-fittings-and-press-systems.
Acrylonitrile butadiene styrene (ABS) pipes are mostly used for vent and drain lines. They are made from a thermoplastic resin and look similar to PVC pipes but are black in colour. ABS pipes are slightly softer than PVC but are still fairly durable and reasonably cheap. The only downside is that they can degrade and warp if exposed to sunlight/UV rays for an extended period of time.
Flexi pipes are a flexible tubing solution usually made from stainless steel. They are commonly used for connections to appliances such as washing machines, sinks, toilets, and water heaters. These pipes should not be used inside walls or under floors. Flexi pipe is available in many lengths and sizes and is reasonably durable. They are, however, relatively expensive.
6-Galvanised steel pipes
These tend to be found in older homes and are less-commonly usually used in newer properties. Galvanised steel pipes are rigid, corrosion-resistant and long-lasting but are relatively expensive to install. They are still widely used for gas networks.
