I was just there
Babe: You already received plenty of advice on clean the drains, so I won't discuss that.Last week, I just replaced the valve to the thru-hull. My old brass valve was frozen for several years, which isn't a very safe thing. The valve that I replaced it with was a 1/4 turn, all plastic ball valve. I had a slow leak near the battery compartment, (of my 1980 C-22). I had thought that the leak was from between the pipe coming out of the "volcano" and the body of the brass valve, but after taking the valve off, I discovered that it was coming from between the pipe and the fiberglass that formed the volcano around the pipe. I was a little horified to see this, but I don't think that this is too unusual after thinking back about conversations that I had with friends about their C-22s, and comments that I have read on this fourum. I wrapped a layer of fiberglass cloth around the pipe, and over the next few days brushed many coats of epoxy into and onto the fiberglass cloth.I also replaced the vinyl hoses with new ones, and replaced the T, mostly just to save time. The new hoses were much softer than the old hoses which were hardened from age. The one volcano that came from the port cockpit drain also was weak, and leaking. I wrapped fiberglass cloth around this pipe and also built-up layers of epoxy around that little volcano too. Does your thru-hull valve work properly? I reread your article above, and it sounds like you did your plumbing work with your boat in the water. If your valve were open, or doesn't close properly, I'm told that the boat would sink, especially if you were to remove it. The pipe coming up from the thru-hull is 13/16 inch inside diameter, so I certainly wouldn't want to try rwmoving the valve with the boat in the water. If you already cleaned out the hoses that connect to the "T" on top of the thru-hole valve, I suspect that the thru-hull valve may be clogged or not opening fully. I just checked the one that I took off, and it's wide open straight through. I can now see the water level inside the vinyl hoses with my boat in the water, and it's about 1/2 way between the "T" and the bottom of the brass pipes from the bottom of the cockpit. If when you removed the "T" and had your valve open and the water only "seeped" out instead of gushing out, I think that your valve is clogged. I know that when I was working on this with the boat on the trailer, I could see the light coming from around my keel, over my driveway. I hope this information helps you or someone else. I hope you enjoy sailing around Havre de Grace. We have sailed our boat there twice, and we really enjoyed that town. It a nice to walk around. I hope you enjoy sailing around the the Northern Chesapeake too. There are many places that you can cruise your C-22 to. There will be a Fleet 10, C-22 cruise starting from Middle River later this summer. It's really fun sailing with a bunch of C-22s. Aldo
