PEX fittings are economical and easy to install when installing piping systems. They are also relatively inexpensive, depending on the size and budget of the project. Additionally, PEX pipe is more durable than traditional copper pipe and will corrode and rust over time. Here are some tips to make your PEX pipe installation as smooth as possible:

How to connect to PEX

You can use several different methods when connecting PEX Pipe Fittings. Some of the most common methods involve expansion or compression. The extension method is easier to do and works with oversized accessories. This method eliminates the need for pipeline pressure tools, which can be dangerous and lead to leaks. However, you should be aware that this method can also be expensive and difficult to redo if you make a mistake.

Another way is to use a one-click connection system. This system requires fewer fittings than traditional rigid piping, so installation is usually much faster. Another benefit of push-fit connection systems is that they allow you to bend PEX around corners without the need for connectors or elbows. Plus, PEX lets the water flow silently, eliminating annoying noises caused by water hammer and knocking.

The most popular connection method for PEX fittings involves the "crimp" method. With this method, you slide the ribbed fitting into the PEX tube and press the sealing ring around the connection point. These sealing rings are usually made of copper, but can also be plastic or brass. There are teeth on the inside of the sealing ring to make the connection stronger. You can find seal rings at hardware stores, and the tools to install them are relatively inexpensive.

Problems with PEX Fittings

If you've ever had a problem with PEX fittings, you're not alone. There are several common problems that plague this material. These include leaks, blockages and broken fixtures. Additionally, the zinc present in the PEX tube can leach out, causing a problem known as dezincification. This condition can weaken brass fittings, and zinc buildup can cause them to leak and burst.

PEX accessories need to be installed correctly to function properly. If one or more pieces are damaged or broken, the entire accessory will fail. This can cause leaks or flooding and require a call to a plumber. In recent years, a large number of homeowners have been affected by problems with PEX fittings.

Pex pipes can be chewed on by pests and rodents. Because PEX is plastic, it is more susceptible to pest damage than metal tubing. For example, mice can gnaw through the material, although this is more of a rodent problem than a plumbing problem. Another problem with PEX is that it cannot be installed in high temperature areas. Also, you cannot connect the PEX directly to the water heater, making the system unsuitable for use in such areas.

Precautions for wintering PEX pipe fittings

In winter, PEX fittings should be insulated to prevent freezing. It's also important to disconnect external faucets to prevent water from freezing and bursting pipes. Taking these precautions is essential for the safe and efficient installation of PEX piping.

Before installing PEX fittings in cold climates, be sure to use the correct material and follow installation instructions. For example, do not use traditional pipe thread compounds, putties or mineral oil products. Never use any unknown mixtures as they may damage pipes and fittings.

Another thing to keep in mind is to make sure the PEX fittings are properly protected from UV rays. UV rays can cause PEX to crack and become unusable, so avoid prolonged exposure to sunlight. Some manufacturers make UV-stabilized PEX tubes that can extend exposure to 6 months. However, this is not a permanent solution.
