FAQs
Can I use this coupler with copper pipe?
This coupler is designed for use with compatible plastic pipe systems; it is not recommended for use with copper piping.
Do I need a pipe support liner?
Yes, when using plastic pipe, a pipe support liner is essential to maintain the structural integrity of the pipe end inside the fitting.
Is this reusable?
PolyPlumb fittings are designed for permanent installation, though they can often be removed and replaced if necessary by following manufacturer-recommended disassembly techniques.
What is the maximum pressure rating?
The coupler is designed to meet standard plumbing pressure requirements; please consult the specific PolyPlumb system data sheet for exact pressure thresholds.
How do I ensure the pipe is fully inserted?
Mark the depth of the pipe socket on your pipe with a pencil or marker, then push the pipe into the fitting until that mark meets the edge of the coupler.
Troubleshooting
Joint appears to be leaking
Remove the pipe, inspect the seal for debris or damage, ensure the pipe was cut squarely, and re-insert ensuring it is pushed past the internal O-ring.
Pipe will not insert into the coupler
Ensure the pipe end is not deformed or oval, remove any burrs from the cut, and check that the pipe support liner is properly seated.

Setup, Compatibility & Care
To achieve the best results, ensure the pipe ends are cut square and are free from burrs or sharp edges that could damage internal seals. When working with plastic pipe, it is critical to insert a pipe support liner into the end of the pipe before pushing it into the coupler; this prevents the pipe from deforming under compression. Always check that the pipe has been pushed past the 'O-ring' seal for a secure connection. For care and maintenance, avoid using harsh abrasive cleaners on the exterior of the coupler, and periodically inspect joints in accessible areas to ensure no signs of weeping or moisture are present.
