The Underbelly Leaking

Last week we purchased a used 2002 Keystone Montana 3295RK, we love it. It's great. Buuuuut, we had been trying to clean our tanks because we keep smelling something. I don't think its black water. It smells like old stagnant water, so we assumed its from the grey tank or from the washing machine. After trying to flush all the tanks we noticed the underbelly leaking, not just dripping, a constant stream. It's leaking right where the pipe connection meets the black underbelly. I'm hoping that the water isn't on any wood but I don't know how any of this works or whats behind that black underbelly. Would it be stupid to puncture a small hole so the water doesn't spread elsewhere and then patch it later? We did call a mechanic who said he won't be available for a few days /: Any suggestions would be great.

Thank you,
Victoria and Jensen

I would remove the under belly, my guess is that the black tank drain line has separated from the tank, This is common for earlier Montana's, had 2 at the park last year. poking a small hole to drain the water is not a bad idea, it will help remove the standing water.

Go ahead and punch a hole nearest to a low spot around the drip/leak. Wait til it stops, then hook up water and turn it on to see if the water leak begins again. If not, then try the tank flush to see if that starts the leak--if it does, then probably the backflow preventer valve is leaking. If it begins again right away, then you will just have to start looking for it in the basement area where you can see the plumbing.
Good luck.
Joe

Normally, I would agree with Joe on this approach. The reason that I said about removing the underbelly is due to past experience with the drains breaking away from the black tank on Montana's.

I agree with franka548, you need to get that underbelly pulled down and see where the leak is coming from. Also if the insulation in there is wet you need to dry it out/replace it after you fix the leak, don't cover it back up with it wet, it will mold.

When you punch the hole in the underbelly (good idea!) reach 'over there' and don't do it over your head/face!

punching hole to drain is a must. After wards, you will need to remove the wet insulation and replace. you can patch holes with gorilla tape. Its not that hard to remove the bottom, just time consuming. good luck

I have been working on replacing some of my underbelly material--it is not rocket science, but can be frustrating working on your back and having lots of junk from years of travel, fallout. Use eye protection. As mentioned, get all the wet insulation out and throw it away--replace with new material after finding/fixing the leak. Looking into the underside of these units is eye-opening as to how they are put together and what corners have been cut. Lots of times the screws/bolts holding the underbelly material will be rusted and need to be replaced also--consider using stainless steel screws to replace those that can't be reused.
