Oh, the pleasures of a manual pump for the holding tank!

[Tayana42]

The main "pleasure" is the odor. I have a Vacuflush toilet, a fiberglass holding tank, all OdorSafe hoses, and a Whale Gusher Triton pump for manual discharge of the holding tank. No odors anywhere except through the Whale pump which is now 7-8 years old. So, I'm figuring it's time to rebuild the pump. My question is this, should I use the neoprene kit (that's what it is now) or use the nitrile kit. Would nitrile be more resistant to odors or just more expensive?

I'm guessing Nitrile might be a little better, but It would just be a guess.

The best advice on vacuflush systems that I have ever found came from Peggie Hall, Specializing in marine sanitation since 1987 and Author "Get Rid of Boat Odors - A Guide to Marine Sanitation and Other Source of Aggravation and Odor" Published by Seaworthy Publications. She is no longer participating in this forum, but try some Google searches for her advice, or find her book.

Edit: I just took my own advice and bought her book on Amazon.

Just so that others reading this do not get the wrong idea...

Manual pumps are no more likely to smell than electric ones. Manual or electric makes no difference at all. The materials used, and their age, are the issues here, not the fact that the pump is manual. And, by the way, most pump manufacturers will tell you that they need to be rebuilt periodically. 7-8 years is a very good lifetime to get out of any head pump.

I'm not questioning that it is time for a rebuild. Only asking if the neoprene or the nitrile is better for holding tank discharge?

Peggy is awesome. A few yeas back, after asking her a question my phone rang.

I have 2 copies of her book. 1 on board and one in my office where I do the refit planning.

Is there a way to modify your existing system to a gravity discharge? Might be the time to make this sort of change. No more pumping.

Tried that one! don't recommend it. without some sort of pump you're at the mercy of the infamous clog. Happened to me at the worse time. What a mess, literally

The gas permeability of Neoprene (chloroprene rubber) and Nitrile (acrylonitrile butadiene rubber) are about the same, so for direct odor permeation no real difference. However, neoprene rubber actually absorbs water over time. If you have observed odor permeation in neoprene over a long period it is likely that the neoprene has absorbed your wastewater to the point that it is "weeping" tiny amounts through the neoprene. Nitrile doesn't do that nearly as much, but if it takes 7-8 years to get there with neoprene then your soft materials are probably mechanically worn out anyway and the extra cost probably isn't worth it.
