in my utility room a couple of the walls are soft under and around the supply lines for the clothes washing machine i have removed the drywall and it is black. i have a manufactured home so it is all pex tubing, and from what i have seen there is no visible leaking. Has anyone had this issue and what can i do to solve this and repair it?
you need to watch it while the washing machine is running, when it is pulling and flowing water. it is probably a very small leak coming from one of the pex unions. once you locate the leak, then you can talk about fixing it. there are several different types of pex fittings, a few pictures would help.
