4 Things to Know About a PVC Drain

The PVC drain pipe, also known as a PVC pipe, is the most commonly used tool in the plumber's bag of tricks. It has now almost completely replaced the old standard, which was copper pipe, in the US home. PVC pipe is generally considered to pass water more efficiently than the copper pipe, and be less vulnerable to rust and other forms of corrosion. There are so many benefits to the PVC drain pipe that it is surprising that is is most often used to carry water away from the home, rather than towards it.

What Is PVC Drain Pipe?

The PVC pipe is made from Polyvinyl Chloride, which forms a material which is very similar to plastic. This type of pipe was first developed in the 1920s, after chemical mixtures has been altered to make a flexible and easily made pipe. The pipe is often used on the outside of homes, for example in guttering, although it can also be used for waste pipes leading away from faucets, toilets, and washing devices. The reason why PVC drain pipe was originally only used for waste is due to fears that the plastic piping may leak chemicals into the water, making it unsuitable for drinking. You may be able to find some varieties of pipe which are marked NSF-61. These are suitable for use with drinking water.

The Sizes of PVC Drain Pipe

The PVC drain pipe is available in a number of different sizes, depending upon the needs. Common PVC drain pipe sizes are the 3 or 4 inch. It is generally agreed that the 4 inch pipe is the best for drainage, although you will also need to avoid elbow pipes, which were often used with copper piping. The sharp angle of the elbow pipe can prevent the water from flowing through the PVC drain pipes very efficiently, and this can also lead to clogs and blockages. When fitting the pipe, you will need to check with your local authority to ensure that you are using a suitable pipe.

The Benefits of PVC Drain Pipe

You can choose to use the PVC pipe over metal pipes, or flexible plastic piping. Other types of drainage pipes, such as cast iron or galvanized steel are less resistant to root damage than PVC, and you are also less likely to need to repair and replace pipes due to water corrosion. PVC drainage pipe is relatively cheap, and may be obtained at most local home improvement stores, making it a convenient choice for the DIY plumber.

As well as the host of PVC pipes, you can also find a range of pipe fittings and joints which will help you to install the pipe in your home. With a drain pipe carrying water to a municipal sewer, you may find that you need to attach a particular joint, which will keep your PVC separated from your copper pipe.
