WH PEX hose connector needs to be replaced

My water heater GTH10 cold water line developed a leak, the rubber inside the thread-on connector is failed. I put a flat o-ring into it, it worked for a few months now it leaks again. Time for a real fix. Has anyone done this? Appreciate any ideas.

HD doesn't carry that seal. Went further away and got it in Camping World. Took a few minutes to pick the old out and put the new in... Viola! Love this board!

I thought that pex recommends that it needs to be installed a specific distance away from a water heater to prevent the pet from overheating and deforming. I could be wrong as I remember that from several years ago when installing pex in our boat.

Luckily that is on his cold side. But I’m sure the hot is the same

The PEX lines and WH are OE items... Funny the hot water side is fine (but I bought a spare just in case...).

When I had my plumbing biz we did all commercial work and never got into the plastic stuff. But I do believe you are supposed to be away 18 inches on the water heater

Bummer, CC didn't follow the rules .

Last night I did de-lime procedure. Too much deposit in it, especially near the drain and the T&P valve/anode, long due .

Neither did Newmar , or Triple EEE , my memory isn't good enough to go back to pre 2005 for my other RVs . I can't even remember if they had PEX.

PEX all the way to the WH. in my coach and last 5er.

New WH in the S&B this year , plumber did PEX right on top.
