QuestionsCategory: QuestionsRouting Potable Water Supply Lines
Handyman Staff asked 4 weeks ago

I'd like to move some of the fixtures in our bathroom. The bathroom is an addition and access to the space underneath is very limited and difficult.

So, I'm thinking about running the supply lines overhead in PEX. In one corner of the bathroom I have reasonable access from the crawl space, I could come up there and then run above the ceiling to the wall where I want to put a sink, then I could come down in that wall.

My concern is the possibility of air getting trapped in the run above the ceiling. Is this something I should be worried about?
