How do you fix a leaking PEX manifold?

How it’s done:

1. Using the PEX tubing cutter, remove the damaged/leaking section of PEX tubing.
2. Prepare a new piece of PEX tubing that is slightly greater than the length needed to make the repair.
3. Using a Crimp Connection Method, connect the tubing to fittings and check the connections with a Go-No-Go gauge.

What causes PEX fittings to leak?

When water flows through your PEX pipes, the zinc in the fittings can seep out of the fittings, causing a white residue to build up inside the pipe, constricting water flow. It also causes fittings to crack or break, leaking water within your walls or underneath your house.
