Ok, I'm working on overhauling my Bristol 29.9. I'm replacing pretty much all of of the thru-hulls, seacocks, and all of the ancient plumbing. I want to run this by you all and gather some opinions.
For the seacocks, I'm basically planning to do what Compass Marine recommends at Replacing Thru-Hulls and Seacocks Photo Gallery by Compass Marine How To at pbase.com
. Groco says to use 316 stainless bolts or lags. I'm not sure whether to bolt through the hull from the outside, lag into backing blocks from the inside, or purchase Groco backing blocks and bolt into the hex nuts. Thoughts?
And hoses...oh hoses. I've been agonizing over the options for hoses and think I have it figured out:
- For the 3/4" freshwater system (non-pressurized), I'm planning on using Trident Marine Reinforced PVC Water Hose, likely from Discount Marine Supplies.
- For the 1 1/2" sewage lines, Trident 101. ~22ft. Any leads on the best place to buy this?
- For the 3/4" holding tank vent line, Trident 148.
- For the 1 1/2" cockpit scuppers drains and sink drains, also Trident 101. ~10ft. I know these don't need to be odor safe, but I can figure out a better (ie cheaper) hose to use that's still adequate for critical below the waterline use.
- For the 1 1/2" potable fill lines and manual bilge pumpout, Trident 148 or 144. ~20ft.
- For the 1 1/8" automatic bilge, Trident 148 or 144.
Looks like it's easy to buy 50' lengths of Trident hose at a good price from Discount Marine. I'm wary of Shields after reading reviews, etc but it's definitely easier to go to WM and buy shorter lengths of the equivalent Shields hoses. Thoughts?
I'll take any thoughts, suggestions, or other ideas!
