flood from failed compression fitting w/pex
One of my clients has a newly-constructed house and is now dealing with a sizeable flood only about a month after they got their CO and moved in. On the first floor, a pedestal sink apparently had one of its pex supply lines essentially slip out of the compression ring of the angle stop and spray water all night long (couple hundred gallons estimated). Much of the hardwood is damaged from water that traveled through the subfloor.
Interestingly, this house has had the water on for months, including that sink, so everyone (builder, plumber) is wondering why it didn't leak until this episode and say they haven't seen it ever happen like this before. Anybody ever come across a similar situation?
The homeowner is rattled, as you can imagine, wondering if other connections are suspect. I think it's just that the compression nut wasn't tightened enough to compress the vinyl ferrule, and that it was just bad luck that it didn't leak until this happened. Anybody seen a similar issue with pex supply lines? Thanks. BTW, the supply coming out of the wall is plastic (pex or cpvc?) has a lot of play and may not have been clamped to a stud nearby. Seems that way, anyhow.
