Our 1984 CD 30 plumbing systems need attention. The water system is manual, and both the galley and head sink and drains are showing discolation and rust. Any ideas about sources for replacements? It is also possible one or both pumps need repair/replacing. I understand the Whale head pump is no longer made, and I'm considering a hand pump for the galley, as well. Anyone done this?
The other issue is the holding tank, to which I cannot pump. I have replaced the head. From earlier posts and some looking around it appears that the vent hose from the holding tank (which is empty) may have condensation in it due to the fact that the wooden blocks to which it is attached on its way to the transom have come loose from the hull, allowing it to sag considerably. I'm assuming that with the help of a dwarf robot with superb manual dexterity I can re-attach these with two-part epoxy. Again, any other ideas or suggestions?
Thanks

When you are finished with that dwarf robot with superb manual dexterity, I'd like to borrow him for several projects on my boat.

Re: Plumbing
Joe,
The drain tailpieces are soft brass I believe, and corrosives from foods and cleaners etc. eat away at this metal over time. My drains in the galley were both paper thin. So I went to the hardware store and found a replacement tailpiece that worked fine. This was a dangerous sitaution in that the sinks tailpiece is normally underwater, or at the water level, so if it corrodes thru above the hose, you could get some water in the boat.
Stainless should clean up with Zud or some other oxalic acid based cleaner made for rust. Look at a large Supermarket for an abrasive cleaner for rust.
I believe that the repair kits for the Whale pumps (galley foot pump) are still made. I got mine from Defender about 6 mn. ago anyway.
I don't like the head vent on some of the Cape Dory's. I think that the ones that go to the stern before venting are a poor design, ignoring science. The way our 1983 CD30 is vented is the better solution..which is basicly straight up from the tank to the starboard hull, as high as possible, under the rail, just opposite the tank. This allows the tank to vent immediately and easily, and avoids the long hose run with sags and pinches (resistance)in it. It's a cinch to clean with the waterhose while pumping out.
When someone has used the head, and pumps merrily away, I worry about how my company sitting in the cockpit sipping the Gin and Tonic, and memorizing the sunset over the lake will like a fairly strong puff of concentrated head air as it wafts over the transom.>'snifff..whats that wonderful odour dear??'<
Another thing, this vent hose permeates with foul odor over time, and needs replacing when you replace the head effluent hose to the tank. The long run is a bear to replace, I'll bet..having snaked wire through that path.
I wonder how effective a vent that hose is, with the resistance of that whole run.
So in other words, maybe think about putting in one of those vents up forward and your system will probably smell better. ..and the whole world will be yer oyster!
Hey..I have finished mounting the new alcohol burners in your old stove..which looks like new now. I am going up to the boat next weekend to pull the old one and replace with the newly rebuilt/20 year old one from you. This idea looks like it may work out!

Re: Plumbing
I'll take thirds on him when you are done with him!! I should be able to keep him busy for six months or so.
Seriously though......... Larry is right on the head vent. Run it to your bow up under the rail. If you are going to that trouble do yourself a favor and add a second vent as well to facilitate cross ventilation bringing plenty of fresh air into the tank. Put a hull vent fitting on both port and starboard of the bow. Add a second vent nipple to your tank. Run hoses from tank to vent fittings as straight as possible, no 90 degree bends at all, no low spots.

Re: Plumbing
Thanks, Larry and John, for the advice on changing the vent. However, I remain a tad confused. Larry, in your configuration, I understand the vent is located just below the rub rail on your starboard side at a point alongside the tank; what danger is there when heeled? John's suggestion to take it forward may be an improvement, but I'm wondering if that's more or less hard than repairing the situation I've got. Where do the runs go and where do they attach? Thanks.

Re: Plumbing
Howdy Joe,
The vent we have is factory installed..and it is about half way between the bow and the anchor lockers bulkhead..high as possible. I believe it is perhaps 5-6 in. below the rail. There should be no danger from water intrusion in that fitting, do to the flare of the hull, and height above the water. Don't forget that this area has the highest freeboard of the whole enchillada..er, boat. It should be an easy add..just drill out the needed hole, glop on some good 3M 4200 (not 5200!!), and attachthe back nut to the fitting. THen route the hose straight to the tanks vent nipple, with perhaps an extra inch or 2 for contraction in the cold. Hose clamp both ends of the hose of course (foul air). If putting in a second fitting, you will need to put in a second vent nipple on the tank. From talking repeatedly with Peggy, the Potty Princess (Peal Products), she advises two vents but of a 1 to 1 1/2 in. diameter size. I cannot see doing that on my boat anyway. So I use this one tiny vent, plus those little blue powder filled bags of chemicals. Oh, and *all new hoses* for the head..using Sealands expensive white hose. But this has worked for 4 years now -without any exceptions. No smell.
