water leaking from belly

[Idahorv]

I was gone for 3 days and my neighbor helped me out by dumping my tanks while gone as it was freezing and he was concerned. We came home to water leaking from the underbelly. I discovered the back flush had been left on, not full on, but still on. I shut all water off to the RV, drained black tank, gray had no water and it is still dripping. Gage show black tank full How much water can the underbelly hold and is there a chance the tank has split open? Also do I need to dry out the underbelly. I will check it all out in the AM in the daylight.

If it's dripping from the underbelly, there can be an amazing amount. I filled all the tanks on a new unit for PDI. Came in the next morning and black tank showed only 1/3. Lifted tongue with forklift and water poured out of the rear seam. IIRC it was a 40 gal tank, so the underbelly can hold quite a bit.

Now, if the black rinser was running, it will fill the tank and at some point the water pressure has to be relieved. I've seen it come out of the vent pipe and onto the roof.

I would carefully remove some screws from the edge of the coroplast and drain as much water as you can. Wear gloves at least to minimize your exposure. If the gauge reads full, try dumping and see if anything comes out.

Once your sure all the standing water is gone, you can fill the black tank and if it's split, you'll know it soon enough.

Thanks, it is down to a dribble now. I'll raise the front in the AM and then remove the panel. Opened black tank and huge amount dumped. Gage shows 3/4 full, but left it open until AM I am sure my neighbor will be helping.
