Jas,

A big part of the problem is the material used in that gate valve..


This is a quote directly from the USCG..

jaschrumpf is on a distinguished road
I'm not arguing. This goes on the list of things to do in spring when I have her hauled for painting. There's another gate valve still on the boat that looks new, but it also looks like a Home Depot special. It'll go too.

I'm not especially surprised. You should have seen the wiring that I replaced last year...

Ouch and double ouch on the wiring..

I just hate to see anyone loose a boat over something so easily preventable. I have personally had a PVC elbow, that was used by a big name builder back in the 80's, crack in my hand as I attempted to remove it. Fortunately this boat was on the hard at the time. I have a friend who had one threaded onto a bronze thru-hull by a PO and the PVC valve split at the threads due to differing expansion and contraction issues. His boat was in the water at the time and the leaking prompted him to rmove and replace it....
