Default Another hole in per pipe,why is this happening???

Got call last sat. Said mobile home had leak on hot water line at water heater,went there and found a small hole in the red pex line right below water heater,this is the third hole that I have repaired on this trailer.do not know what brand of pex they used when building mobile home but it seems much cheaper than my zurnpex that I use.there is a prv on incoming service line with about 60 lbs pressure at faucets,but there is no expansion tank or valve at water heater,I told them that an expansion tank or valve would stop this but now I'm not so sure.shouldnt the pex pipe hold enough pressure before blowing a hole that would make the t&p valve pop-off????i don't understand why this pex pipe keeps blowing holes in it before the popoff valve releasesany ideas???

Dang spell check,per should be pex

Mice. During the winter they love a hot drink.

Like a pin hole? I've run into a few pin hole leaks in PEX and each one was on the hot side next to the heater. I have heard various potential reasons given but I can't remember any of them. The ones I saw were on rahau or zurn pex.

No,all these holes I have repaired are bigger than pinholes,little bigger than pencil lead I'd say,my sue pex that I have used to repair these holes with has not had a hole come in it as of yet,pex is pex,why is this pex pipe not holding enough pressure to let popoff valve blow off if it is thermal expansion???i love pex but stuff like this really worries me

I have had pex in one of my houses( the whole house is plumbed in pex) for about 11+ years coming off the water heater, no issues yet, but to answer your question, yes pex should hold alot more than 60 psi before failing, im starting to think water quality or chemicals added to the water are having and effect on both copper and pex pipe, since we( plumbers) are the first to get called for a leak, im thinking there should be a data base to see if these problems are concentrated in certain parts of the USA, for both copper and pex...

piping within 30cm vertically or 15cm horizontally from a strong heat source such as flue vents is not installed properly and is not expected to survive very long.

The first two holes I repaired about a yr ago and both of them were within 18"-24" of the hot outlet on the tank,but this last hole was around 4'-0"" from heater and it was thru the floor about a foot below heater,seems like it just keeps going away from my zurnpex pex,maybe they used crappy pex but I thought pex was pex,maybe I'm wrong,but I can't figure it out,it should hold enough pressure for popoff valve to blow IMO
