Sewer in the basement

[Twiffer]

Good morning and thank you for the Birthday wishes in my email, Keystone RV Forums. We are permanent residents of our Montana High Country, 318RE. We are plumbed into a septic system but don't leave our black water open. We drain it when necessary so solids don't get stuck in the system.

This morning, hubby was using the washroom and I was in the living room when we both heard a noise (explosion?) like something dropping in the basement or someone hitting our home (not possible where we are) or something blowing up (not loud). The place shook. We went outside to see sewer seeping out of the bottom of the basement under the bathroom. Hubby took the panel off and got the remainder of the sewer out (two small buckets full) and inspected for damage. He can't see anything wrong. We even held the flusher down for some time to allow a lot of water to go through the system and it all went exactly where it should.

It's been warm here. I'm wondering if it somehow 'burped' and overflowed somewhere but nothing came back up the toilet bowl which seems the least point of resistance.

Called the RV Tech from another dealership than ours (ours is closed today) and he couldn't put his finger on it either.

Anyone ever experience anything like this?

If something burped and overflowed, that something is broken and needs to be repaired. There is not any overflow in any of the waste systems on these rigs. It sounds like, until you have someone really open things up to locate what has failed, you should maybe up your black tank drain schedule so you don't 'overflow' into your basement. Good luck.

A RV repair person couldn't suggest that you have a broken 'something?'

I would susupect that your black water tank is broken if you had 'leaking' outside of where it should be. You need to get the bottom of your rig off and find the problem now.

After you figure it out make sure you have venting and dump more frequently...if two people--every 7-10 days or so.

Did your husband have burritos the night before? Perhaps that was the loud explosion you heard?

Sorry just couldn't resist!

x2 on getting to the bottom of the problem immediately, possible that the joint between the vent stack and the black tank came unglued? That would be on top of the tank where it's very difficult to see. Get pro help immediately!
