2021 Reflection 5W 295RL 150 Series: I connected a hose to a fitting at the dump valve to back fill/flush the black tank and forgot to turn the water off
By the time I turned it off, I had water in the sagging winter lining beneath the frame. I slit the lining, drained the water and ran a Shop-Vac for most of the day to dry it out. Question is - where was the likely overflow leak?
My guess is 1) The Grommet on the tank that feeds the air vent , or 2) where the black tank connects to the toilet. About a half gallon of water was in the toilet but the seal apparently held back most of it until the new leak occurred? When I opened the toilet flush valve there was pressurized air suggesting the water had found a different exit. No water came out the roof vent and there's nothing on the bathroom floor to suggest water backed-up through the tank wash airlock valve behind the shower controls. I will partially refill the black tank and hope keeping it below the toilet-to-tank seal is the solution.
Thoughts on where else the water might have overflowed from?
Oct 2 update: It was #3 - Black tank valve at the tank. As a gravity feed system, the factory seals the valve joint with a Dicor-like product and hose clamp. But under pressure as a result of me leaving the back flush unattended, it separated (see photo) enough to leak. I separated the winter liner about 2 feet forward of the steps on the starboard side and used a rope fed aft to separate the joint for cleaning. Note that the valve includes about a 3in extension that slides INSIDE and into the black tank opening. After cleaning with Goof Off, I applied Dicor Self Leveling Lap Sealant and let it sit for a while to travel a bit into the joint. I then reversed the rope forward to the hitch pin and pulled the joint together. Remember to let this sit overnight BEFORE re-tightening the hose clamp or else you'll simply squeeze your "gasket" out of the seam before it sets. (Interesting note: There is only one tank heater on the bottom of each tank, at the drain end.)
