$hitty situation for me

So, just recently purchased a new to us 2012 Cougar 325SRX. All looked well. Upon returning home from our first trip with it I had to park it overnight in a temp spot in our driveway to unload the garage. In the morning I notice dripping from the belly pan. Sure enough its black water.

I finally pull part of the chloroplast down as best I can without damaging it, also noticing a couple sections have been taped indicating previous repair.

I find my black tank leaking from the front right corner somewhere near the top. So, at some point this week I plan to get deeper into it and get the tank dropped to see what's what.

A couple questions:
1) Is the black tank vented? I would assume so but from my quick look under there last time and the layout of the bathroom, not sure where a vent would run through to the ceiling.

2) What is the best source for the black chloroplast insulation? I want to replace the entire section that was cut by someone prior.

Thanks for any feedback.
  • Thanks for the link. No current problems but nice to have a product source in a problem does occur.

    Black tank work is no fun at all. My 5er has the electric Waste Master system & I have had to replace the valve at the tank. Quite the job.

    IF it is a hole.. GOOP works fairly well. Sticks to most everythign LIkewise Eternabond and on a different part of the MH I'm trying Flex Tape (NOT long enough to comment yet.. NOT a water tank of any kind).

    IF it is the gasket for the vent pipe.. Well. that ... in theory.. can be replaced.
  • The black tank vent will most likely be on the roof. It's a tube that runs from the tank to the roof and will have a cover with a gap between the top of the tube and the cover to allow venting of the tank while preventing rain from going into the tank.
  • p.s don,t wear your sunday suit when working on it, good luck ,you might want to do a major flush and empty before you take things apart. if the vents in a easy spot cut it and fix with a rubber sleeve.
  • Look on the roof above the area of the black tank for the vent pipe coming thru.
  • It's coroplast, not chloroplasts. You might be able to buy some from a sign shop.

    As far as the vent for the tank, check in the nearby closets located over the tank. It is common practice to run it up through them in one of the 4 corners. It is usually 1-1/2 inch black ABS pipe.
  • Yes it is vented. Most people use foam board, which you can get at Lowe's or Home Depot, as water resistant insulation. Use the 2" board.
