PEX Plastic water fittings.

After 7000 miles of trailer use, a PEX Tee fitting sheared clean off by the water heater. A major flood ensued when we hooked up to the city water supply via a pressure regulator and hose. Has anyone else experienced this or similar PEX fitting failure? I suspect a bad injection molding job on the PEX plastic TEE connector. The trailer is a 2012, 184BH Swift manufactured during early months of 2011.

Have not heard of any failures on Jayco. Sure hope the factory warranty takes care of it for you.

I had my first problem with my 2004 this past weekend, the cold water fitting on the bathroom sink broke off. After fixing that the valve for my low point drain started leaking. I ordered 2 new valves & a few extra parts from www.directpex.com

Bruce, sorry to hear about your flood. I'm not a big fan of plastic tees. Can you replace it with a copper tee? My house is filled with plastic tees. Thankfully none of them have let go. Having read numerous forums over the last few years since they've used pex , there hasn't been very many posts about people who have run into these problems. I suspect that it being close to the water heater and possibly something wrong with the tee itself contributed to its failure.

I replaced the plastic PEX TEE with a barbed brass TEE. I feel better using a metal TEE especially close to the water heater. I pressure tested the plumbing for several hours then put the lower bunk back together. All is well, I Hope!
