Original Head on PSC 34

I'm working on replacing all of the hoses for my head. Of course I had to remove the Raritan PH head in the process. There is a 2" thick piece of mahogany on which the Raritan sits. Upon removing that I discovered the holes for the old head. I'm guessing from the footprint that it might have been a Groco K-H (the Groco is higher than the Raritan as well, which would explain the 2" wood pad).

Does anyone know if mid-90s PSC34s had a Groco? Any reason that I would want to go back to the Groco? It certainly seems more robust than the Raritan.

While I'm posting, any thing else that I should keep in mind as I change out all the hose? I'm cleaning all the hull and probably going to repaint while all the hose is out of the way. I'm replacing with the Raritan Sani/flex hose. Also going to clean the holding tank (my guess is it hasn't been done in a long time, if ever).

Yup, mine has a Groco Model K. I haven't had any problems with it, so far, although I did replace the flapper valve last year. I've been considering replacing all the sanitation hose also, but it's not that high on my list of priorities yet. Given how stiff the original Trident hose is, it cannot be an easy job. Let us know how it goes.

Thank you Joost. After posting I did some additional digging and research. I'm leaning heavily toward switching back to a Groco. The Raritan isn't a bad piece of equipment, but it's not built like the Groco.

I'll let you know how the change goes. I just have the clean-out hose and two shorter pieces left to remove. So far not too bad, especially since I could get the Sawzall in to cut the longer pieces in half. That made it much easier to remove.

Re: Original Head on PSC 34

Bill, we have a Groco on our 1987 PSC 34 and it works well. A few years ago I replaced the hoses to and from the holding tank, replaced the plywood lid on the holding tank, and cleaned it out. I'm glad that's over! Anyway, the worst part of the job was replacing the hoses. I had a terrible time positioning myself to be able to attach them to the holding tank. Good luck.

Thanks for the info and encouragement. I know that it isn't going to be fun, but I'd rather be doing it in the cool of early spring in Cleveland than on an extended voyage. It's so tight, both under the sink cabinet and in the space immediately inboard of the holding tank, where the pump is. I've heard that the Raritan Sani-flex and a good heat gun will help.

Thanks Bill. That's good information, I hadn't thought about trying to get underneath the plinth.

I wonder why the PO removed the Groco. They also replaced the deck mounted table with a bulkhead mounted table. A decision that I would not have made either.

Re: Original Head on PSC 34

OP mentioned cleaning out the holding tank . OP does your tank have a full indicator ? I tried to find the one we have but no luck . Ours is a simple set up that consists of a plate that holds a shaft that a float goes up and down on and makes a 12V connection and turns on a light . Anyhow to mount this thing you hole saw a hole and screw the thing down with a nice gasket , in the past it also doubles as a access port so I can see in there and I can get a hose nozzle to blast the thing clean .

To be honest, I haven't paid much attention to it yet. I do know that the first season that I owned the boat, I managed to pressurize the holding tank to the extent that when I opened the clean out on deck, had I not opened it slowly and the pressure was relieved, I would have been covered in $hit. A full gauge might have helped me to avoid that mistake. I'll check once I get to that point.

I just cut the hose with a dremal cutting blade in the middle and then then carefully cut lengthwise at the end so so it would easily break loose. The original hoses had some blue sealant that prevented just being able to twist it off. Newer hose is much easier to work with. Pick a breezy day so you’ll have some fresh air flowing through the cabin.
