Dave: please describe the manifold you installed. From: Dave Godwin via CnC-List Sent: Saturday, February 02, 2019 7:13 AM To: cnc-list@cnc-list.com Cc: Dave Godwin Subject: Re: Stus-List Replacing Water Lines...
I replaced all of the original grey plastic pipe in our boat. With the exception of a section where someone (ahem, looks at self…) ran a screw through it, it was perfectly serviceable, However, since I am replacing the fixtures in the head and the galley and have adde a transom-mounted cockpit shower I replaced all of it. I used 1/2” SeaTech polyethylene tubing and associated fittings. The job was fairly easy to do and allowed for the building of a simple manifold on the pressure side of the system for the hot and cold outflows. The best thing that I did was purchase the pipe cutters to insure a clean, 90-degree cut on the ends. Pictures available upon request.

My understanding is the issue with this material is in residential use it split open causing a flood, in situations where pressures AND temperatures are high (180F). It was taken off the market and companies were, and still are reluctant to make compatible fittings out of liability fears. Having said that, I've kept the poly-b in my boat as it unlikely to fail since my my water is only periodically under pressure, its only 40 psi, and it never gets really hot. if it was in my house, I'd remove it. Vinyl tubing tends to shrink, yellow and harden up over time. I'd do 1/4" or 3/8" pex if I was running new, but not sharkbites for fittings, there are lots of other compression fitting available at lower cost.

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. David F. Risch, J. D.
