I just replaced all my water lines and fresh water holding tanks last winter.  I used a $30 crimp tool and the band clamps for most of it.  I used some quick disconnect 90s at a low point in the bilge to drain everything down.  I also used distribution blocks and made every fixture a home run.  The pex is smaller in diameter to the usual tube you see in older boats.  So, I could run more tubing in the same space as the old.

This is my first winter so I can't really speak to how well I did with draining but, I'm pretty confident.  I did suck on all the lines with a shop vac.

The nicest part was having an all new water system!

If installing waterlines, are there not tubes one could use that can tolerate freezing – so we could avoid antifreeze entirely . . . . ?

In this era of plastics, surely there’s a way . . .

*Subject:* Stus-List Replacing Water Lines...

I am sure this has been gone over before...so please indulge me.

Replacing, re-designing, water lines in 1981 40-2.  Pex is the obvious choice.   Are there less obvious (and have cheaper tools required to install) choices?

Has anyone improved on the original design?   I am thinking of adding easier accessible manifolds and an additional line for antifreeze and blowing out water.

Thanks in advance.
