…very rough. Early too, as you normally wait till the plywood is up before moving on to inside plumbing and electrical, but as I had two very tight corners I had to pull PEX (cross-linked polyethelene, a flexible tubing) lines through, I though it easier to do this now while access is still possible from both inside and out.
The future bathroom sink has the longest run (all of 10 feet) from the future instant water heater which will be located under the kitchen counter. The other plumbing supply lines for the shower and the kitchen sink will be in the internal wall separating the bathroom from the kitchen. The drains for the sinks and shower all exit directly through the floor (trailer) and will tie into a common grey water tank or french drain once the trailer has a home.
I originally considered running the PEX lines under the trailer so I wouldn’t have to drill so many holes through the studs, but have heard and read that rodents will eat PEX, and I’m still disillusioned with copper (see earlier posts on our bathroom/kitchen disaster), so through the walls we went. I carefully mapped out where the lines go and installed metal nail stoppers so when we nail in the plywood shear walls in the next few days I don’t create any accidental leaks.
