Water Leak in Underbelly

[dalford]

I have a 2016 33IK and have developed a water leak that seems to be below the RV floor and in the underbelly. The only lines that run under the belly are cold and hot water to galley sink, the fresh water tank supply and the fresh water tank return to the water pump.

I have not determined where the leak is but the underbelly is full of water under the front basement.

I’m doing a pressure check now on the fresh water side.

My question i is, before I start removing underbelly covering, where is the fresh tank mounted. I seem to remember it is just behind the axles? The water is showing up in front of the axles so I don’t think it is the tank itself.

Thanks in advance for any replies.

FW tank is a little bit behind the rear axle ... just look for your FW tank drain and it will be just above it. If your pump doesn't continuously cycle ... that eliminates many of the hot and cold water lines. Is it clear water or dirty water? Don't forget about your black tank rinse line.

Thx dieselguy for the ideas. I think i’ve found the issue. it is not in the underbelly but a cold water tee in the basement that is leaking and running into the underbelly.

i had a mobile tech out today and he discover the leak. he did not have any tees on him but will come back next week to tear it apart and investigate more thoroughly.

I drilled a couple of small holes to drain the full underbelly and will remove it to dry out the insulation. i also put a fan in the basement to help dry out the wood.

Save a wait and just go to Home Depot, Lowes, or Menards and get a 1/2" Sharkbite (or similar branded) T fitting. They are really easy to install as in they push on once you squarely cut off say 1/2" of the OEM PEX line.
I carry a spare Sharkbite T and union for those times of need when on the road.
