CD26 Head Question

[Bridget]

I have a Groco Model on board. Does anyone know if this is original equipment? Mine needs repair(it is not drawing in water). Does anyone have any trouble shooting suggestions?

standard equip was a porta potty. the marine head was an option. i suppose one could have requested any unit one wanted. my boat (hull 49) has i believe a groco as well. assuming the seacock is not closed or clogged, it sounds as if a rebuild is needed. kits with instructions are readily available.

I just replaced the head on my 81 CD27. The boat came with a Groco HC (no other holes were drilled, so I assume it was original). When I purchased the boat from its previous owner, a Groco manual was included in the ships papers. The Groco no longer pumped and to upgrade it to the newer HF would have cost about $80 from West Marine. I waited until there was a sale and bought a new Jabsco for $135.

If the water intake line is clear, it sounds like the pump needs repair. Unfortunately, the pump repair parts do not come in the GROCO repair kit -- you would need the Model HC/HE to Model HF upgrade kit to get the pump parts. The upgrade kit is very pricey and you still need the repair kit, which has all the valves, to do the complete job. Together, the cost of these kits is within about $20 of a complete new GROCO MODEL HF head.

I'd suggest pulling the pump out to see if it really IS the problem. If it is, I'd call GROCO direct (someplace in Maryland) and see if you can still get the original pump parts for your unit which is probably the Model HC or HE. If original parts are not available, I would replace, not upgrade, your unit with the new GROCO HF Model. I'd stick with GROCO since the switch over should be a very simple installation. The new and older GROCO units appear to be identical, with the differences being in the internal workings.

John;

I have a Groco in my CD-27 and it is not the original. I just replaced the base; parts are readily available, but will probably have to be special ordered by your distributor.

I noticed some siphoning when the wet/dry lever (by the pump plunger) is left in the wet postition, so I am going to put in an anti-siphon valve in the feed line between the pump and the potty intake.

I also replaced my Groco with a new Jabsco, used the original bowl and seat and saved a couple of bucks. I had rebuilt the Groco completely to address some backflow problems, and found that the rebuild kit didn't do the job. I checked around, and found that Groco's design is not as sophisticated as others (I was told), so opted to upgrade a bit. I also took the opportunity to replace the supply and exhaust lines with the heavy-duty, oder-proof type. They are quite stiff and can be tough to work with, but a heat gun or hair dryer will render them pliable. By the way, the new Jabsco is great and very reliable.

I have also had success with boiling a small pot of water on the stove and then carefully carrying it over to the fitting and dipping the last few inches of hose in it (carefully!) which softens it enough to slip easily over the fitting. Did I mention you have to do this carefully?

Boy, I wish I had figured out about the boiling water. I tried a heat gun, tried soap, tried about everything. The big problem with the new hose (by the way, go to Home Depot if you ever need the hose again, they sell it for 1/2 of the price at marine stores) was that my deck fitting had an OD of 1 5/8, not 1 1/2. The hose is 1 1/2 only. I tried about everything short of turning down the fitting. Finally bought an adapter fitting at a hardware store for sewer lines that connects the two. But I would like to eliminate it, so I'll try the boiling water idea.
