Drain Problem on couger xlite 26SAB

[John R]

Just noticed water dripping down drain pipe to the drain gates. I think its the grey water drain. Anyone how to check it and repair it? Or another cause?

Sounds like the blade seals are leaking. You can try cycling the valves open/closed a couple of times in case it's just a piece of foreign material.

If more than one tank drain out of that point, then you can figure out which one by draining all the tanks and then fill one at a time. We use treatment tablets to change the color of the water or easier diagnosis. The repair will be a bit more involved.

You have to access the valve itself. There will be 4 screws with nuts holding the valves in place and the seals are on each side. 3 choices for valve, and 2 require the specific seal. Should say on the valve:
Bristol- have to use the Bristol seals
Valterra- can use Valterra or Valterra "Bladex"
Bladex- have to use Bladex seals.

Gray tank usually use 1 1/2" and black uses 3".

The drain in question exits the bottom of the trailer and goes into the black tank. The water is leaking around this pipe. The membrane that covers the bottom of the trailer is holding the water.

If the leak is the pipe from the trailer to the tank, then the tank has to be removed for repair. Since the only plumbing to the black tank comes from the toilet, I would remove the toilet and check the seal for the toilet base (foam ring) and the floor flange to the piping that goes to the tank.
In some applications the pipe going into the tank has a rubber seal at the tank, in others it's all glued together. If the tank has to come out you will have to cut the vent pipe also.
