Grey water system leak?

[FFred]

On my 2016 FWS Isata ,,washing dishes in the galley sink causes water to come out from under the shower pan.

It could be a leak in the FW system which is located in the toilet , but I think its a leak in the line to the grey water line to the tank.

Has anyone taken apart the area under the shower , I can nor see a simple way to disassemble the under shower panel to get a look at what is leaking.

The FW pump is in a fitted box behind the toilet , I can see no way to remove the cover box to take a look there .

From past RV and boat living I know I will need to get to it eventually.

Advice before I break out the sledge hammer would be appreciated.

TIA

If the Gally sink is causing the leak then your gray water tank is full and you have a broken connection in your shower drain to the tank. A common problem. Find an access to the underside of the shower and have a look see. this is a drain problem not a FW problem.
does it leak when you take a shower?

Thanks for the reply, The grey tank is empty and we still have the leal.


Happily there seems to be tiny white screws holding a panel under the shower , that I can pull to investigate.

I just noticed a small leak on my grey tank, but it was completely full and after I drained it I saw no further leak. I do plan to check what kind of seal is on the top of the grey tank. Whenever it become full in the past we would see water in the shower pan and just drain it. Maybe road vibration has loosened the seal?

The water pump is under the shower. I bet it’s that.

Yes, it was the filter on the water pump that was leaking.

The horror is the amount of work to access the pump.

Totally avoidable with a better mount method for the covering board.
