PEX (cross-linked polyethylene) plumbing systems have become popular due to their efficiency, cost-effectiveness and durability. PEX compression fittings provide secure connections between PEX pipes, valves and fixtures. However, it is important to follow safety guidelines and best practices when using these fittings to avoid leaks, bursts and other plumbing problems. In this blog, we will discuss some of the safety guidelines and best practices for PEX compression fittings.

1. Follow the manufacturer's instructions:

The first and foremost safety guideline is to read and follow the manufacturer's instructions carefully. Different PEX compression fittings may have different installation procedures and requirements. Improper installation can cause the fittings to leak or burst. The manufacturer's instructions will guide you on how to correctly install and use the fittings.

2. Use the right tools and equipment:

Using the wrong tools or equipment can damage the fittings and reduce their effectiveness. Be sure to use the appropriate tools and equipment recommended by the manufacturer. This may include PEX cutters, crimping tools, compression tools, and clamps. Choosing the right tools can help you to make secure and leak-free connections.

3. Cut the PEX pipe correctly:

When cutting PEX pipes, it is important to ensure that the cut is straight and square. This will help to prevent leaks and ensure a secure connection. You need to use a PEX cutter instead of a saw, as a saw can create rough edges that may damage the fittings.

4. Inspect the fittings:

Before installing the fittings, inspect them to ensure that they are not damaged or defective. Look for any cracks, scratches or other forms of damage that may affect the proper functioning of the fittings. Damaged fittings should be replaced immediately.

5. Use a support bracket:

When using PEX compression fittings, it is important to use a support bracket to secure the pipes at regular intervals. The bracket will help to prevent the pipes from sagging or bending, which can cause stress on the fittings and lead to leaks and bursts. The spacing of the bracket depends on the type of pipe and the application.

6. Avoid over-tightening:

PEX compression fittings should be tightened carefully to avoid damage to the fittings and the pipe. Over-tightening can deform the fittings and cause leaks. Use a torque wrench to ensure that the fittings are tightened to the manufacturer's recommended torque.

7. Use water pressure tests:

After installing the PEX compression fittings, conduct a water pressure test to check for leaks or other problems. This involves turning on the water supply and checking the pressure gauge to ensure that the pressure is within the manufacturer's recommended range. This test should be done before installing any drywall or other finishes.

In summary, PEX compression fittings are a popular choice for plumbing systems due to their reliability, ease of use and durability. However, it is important to follow safety guidelines and best practices when using these fittings to ensure leak-free and secure connections. By carefully checking the manufacturer's instructions, using the right tools and equipment, inspecting the fittings, and conducting water pressure tests, you can avoid costly and time-consuming plumbing problems.
