Water leak into the back passenger basement compartment
2015 MIRADA 35LS which has a bath and a half
On a trip, water began to leak into the large back passenger basement compartment as we drove.
The F/G/B tank were lower than half.
When arriving at a destination, water was dripping from the skirting of the very wet compartment.
The first time it was very damp, which was dried,
The next stop more wet, once again dried,
on the way home the next stop had an inch of water in the compartment!
Every time the water was clean, no smell, no residue.
The Grey and Blank were tanks emptied.
At home, once again dried the compartment, then an unsuccessful search of the leak lead to other investigations.
During the trip the back toilet was not used, but the vanity was.
I checked the back black tank, opened valve and some water did flow out, even though the toilet was not used.
I closed the valve then let the water run in the back vanity sink, then watched to see if the water went into the compartment, soon the water flowed from under the back of the RV, but not into the compartment.
Then I opened the valve and water flowed from the back black tank.
After an exhaustive search on the internet to look for solutions, of overflow, and seals.
I have searched the internet seeking to find a plumping schematic for the 2015 Coachmen Mirada 35ls, with no success.
Please let me know, if anyone has any possible ideas AND solution to this most curious situation.
