OK to pressurize holding tank?
Two years after replacing all the holding tank and head hoses, I'm still trying to determine the source of the bad oder coming from around the holding tank (under the V berth).
I've had good luck in the past with pressuring "closed" systems, pumping them up with air, and then spraying a soap solution on fittings etc. to locate leaks. I figured I could remove the holding tank vent line and put a fitting on it that would allow me to pump the tank up to a fairly low pressure (like 5psi) - the tank is poly and I wouldn't want to rupture it. My concern is that I have a Whale gusher pump connected to the tank for overboard discharge. I wouldn't want to rupture the bellows in that pump. I'm also concerned about the toilet - whether I might damage something there or if it would even permit the tank to be pressurized.
The hoses are a real pain to get on and off or I'd just remove them and seal them up. I'm wondering if anyone on sailnet has ever done this and what suggestions you might have so I don't go makeing a livable situation a real mess.
Thanks and Happy New Year to all!!
