The benefits of using pex fittings on polybutylene pipe

When it comes to plumbing, there are a lot of different materials and methods that can be used. One material that has gained popularity in recent years is polybutylene pipe. This type of pipe is known for being durable and easy to install. 

However, one potential downside is that it can be difficult to find fittings that work with it. That’s where pex fittings come in. Pex fittings are specialized fittings that are designed to be used with polybutylene pipes. They offer a number of benefits, including being easy to install and providing a tight seal. 

How to install a pex fitting on a polybutylene pipe

While polybutylene pipe is no longer used in new construction, homes built with this material between 1978 and 1995 may still have it running through the walls, ceilings, and floors. If you need to make a repair to a section of polybutylene pipe, you’ll need to install a pex fitting. 

This can be done using a simple push-fit technique. First, cut the pipe to the point where you need to make the repair. Next, slip a pex sleeve over the end of the pipe and insert it into the fitting. Finally, use a pipe wrench to tighten the nut on the fitting until it is secure. With just a few simple tools, you can successfully install a pex fitting on a polybutylene pipe.

Tips for maintaining your pex piping system

Properly maintaining your pex piping system is essential to keeping it in good condition and ensuring that it lasts for many years. Here are a few tips to help you keep your pex piping system in top shape: 

  • First, make sure that you regularly inspect your pex piping for any signs of damage or wear. Always fix any cracks or leaks right away if you notice them. 
  • Second, connect your pex piping to an approved backflow preventer. This will help to protect your drinking water from contamination. 
  • Third, always use approved fittings and connectors when connecting or disconnecting your pex piping. This will help to prevent leaks. 

Final Thoughts

Although pex fittings can be used on polybutylene pipe, it is not recommended. Pex fittings are a better option because they are easier to use and more durable than polybutylene fittings. If you have to make a repair using polybutylene fittings, make sure that you use Teflon tape or pipe dope to help seal the connection.
