Pex via Bilge?

Anyone have any advice against running a set of main hot/cold PEX supply lines through my bilge?

My plumbing is a mess and its time to take care of it. Putting the entire plumbing system on one main house pump. I would have a primary manifold in the engine room for the galley, stern head sink, and a set of feeds forward to a secondary manifold that covers the anchor washdown, forward sink and shower.

Would let me go hog wild ripping out tubing through all of the cramped and poorly laid out routes that are there now.

Sounds like a plan. I used PVC because joints and junctions are really expensive with PEX. PEX is more flexible than PVC, but with sinks, showers, toilets, and a hot water circulation system, the number of corners, junctions, and tees got past one hundred, and for that, PVC is cheap.

PEX running under the floorboards is no problem at all.

What you describe, two manifolds tied together by PEX running under the floor is a common configuration in new boats.
