HOW TO INSTALL LEAK-FREE POLY PIPE JOINERS

Poly pipe joiners are easy to use and learning how to install leak-free poly pipe joiners is also easy too:

Incorrect installation
When pushing fittings onto the pipe, ensure the pipe is inserted fully. If the fitting is only partially inserted onto the pipe it will not create a watertight seal. When the pipe is traveling through the fitting there will be some resistance. This means you can think the pipe has been pushed all the way into the fitting.   Making a witness mark will help show how far the pipe needs to be inserted in order to reach half way into the fitting.

Pipe issues

In order to seal tightly inside the fitting, pipe ends need a clean, straight cut. If the end is jagged or uneven, it will not create a watertight seal

If the tubing is cut on an angle, it is unlikely to seal and could also nick the O-ring

One way to avoid these issues is to cut pipe with a pipe cutter rather than a blade or saw

Damaged O-ring
Lubricating and chamfering the end the pipe to will help stop damage to the O-ring.

Excessive pressure
Leaks can occur when the fitting is strained or too much pressure is placed on fittings at a strange angle. If your installation involves a pipe or fitting on an angle, this can create pressure that can stretch the O-ring. This means the O-ring may no longer seal properly and can start to leak. It is important to keep pipe entering and exiting the fitting as straight as possible.

PLASSON fittings are designed to manage this.  Elbow fittings are angled to change the direction of flow. These can be at 90° angles or short-radius 45° angles. Swivel elbows allow you to fully rotate one end so the pipe can face whichever direction is required. These fittings make it easier to deal with corners and bends without over-stressing fittings.
