Joe...If you already have significant scaling in your hoses and valves, you may need to be more aggressive than vinegar. Muriatic acid pumped into the lines is the way to go. Then...once you are clear...you can use vinegar for maintenance.

Yes, its silicone grease. I appreciate the info about the corn oil causing 'more' odor. The vinegar makes sense, I've seen some thick rock hard scaling so I'll give it a try. Too bad there was'nt a lubrication port on the Y valve, accessing mine is really tough. When this one goes I will get the marelon or bronze. Thanks for the tips!

I don't use corn oil, but I do use some Head Conditoner/Lubricant that came with my boat that the previous owner left. Each time we go out, I put a cap full or so down the head and flush into the lines. Haven't done the vinegar yet.

would'nt drinking a gallon of corn oil make you a little bit ill, I have been told a good swig of it before a night on the turps is a benifit.

Yeah...but it is more fun your way Boasun! (g)

And here I always thought that the only way to lubicate the valves was by eating greasy foods... Learn something new every time. ROFLMAO

Thanks for the clarification Cam.

We don't pump it into the holding tank! In the islands there are no pumpouts!!

He's talking about using vegetable oil to lubricate the y-valve, not the pump. BTW, Peggy Hall really frowns upon the use of vegetable or mineral oil since it can cause the holding tank to really stink, since it covers the surface and can reduce the aerobic (non-smelly) bacteria and encourage the anaerobic bacteria (which makes the smells).

Sure...veggie oil or mineral oil once a month helps keep the parts of the pump lubricated and working well. We usually did our monthly vinegar de-scaling and then followed it with the mineral oil. Won't do much good for the Y valves though. The vinegar may be more helpful in that scale is often the cause for broken handles. Marelon Y valves are a distinct improvement on cheaper plastic ones I've found.
