Grey tank drain line separation

[edlynnrich]

So the ABS and PVC threaded male and female adapters that are sold at your local building supply stores are straight threads? I’m guessing that the NPT designation indicates a tapered thread?

I'm reasonably certain that the female tank fitting is tapered, and ETI is sticking a straight threaded male fitting into it. But if you take the joint apart (which you probably can't do without cutting pipe, so you're not going to do this just to find out), you can measure and check.

The male straight threaded fitting intended for a slip joint will be tapered inside the end where the missing sealing ring is supposed to go; a male tapered thread fitting will have a plain end.

I too have the same leak under the sink in 2019 5.0 while under warranty. I too contacted ETI and was told the same, take it to an RV repair shop... After talking with Destin he supplied me with a detail sheet so I could do it myself and be on my way, but the following season the same thing. My thinking is that something is moving and the other component is remaining still, so I disassembled the repair thinking it failed but no, now it looks as though the female collar is leaking! I don't know if this issue would prompt a recall but I feel ETI should follow up on these occurrences.

Don’t hold your breath about a recall with the new management.

They are allowing stoves to blow up and burn people without sending out any warning.

My 2019, 17B began to drip at the grey tank connection.

I found this thread (thanks for all the information!). Because of your posts I as able to repair it fairly easily. I knew just what parts to buy before I began. The 1.5” pipe fitting was sheared right off flush with the grey tank.

The caulking that Escape used didn’t adhere to the tank or fitting at all.

I was able to partially saw through the broken fitting in two places about 1/4” apart with a hacksaw blade. Then apply lots of heat to soften it. Broke out the 1/4” strip using an awl so it then collapsed internally. Similar to drilling out a broken bolt.

I reassembled with two flex fittings, a 3” and 1.5”, and improved clamp to prevent excessive movement that caused the pipe to shear.

I used clear silicone RTV on the grey tank fitting threads.

Overall not as crappy a job as I expected !

Thanks to those that shared, Bob

Just returned from a trip where I accidentally filled the grey tank and ended up with water coming from my lower cabinet where the sink drain goes into the grey tank. When I returned home I removed the foam around the sink drain where I it goes through the floor into the grey tank and filled my tank. Gurgling and water coming up onto the floor and draining out the exterior shell drain next the door step. A quick pull of the grey handle and the tsunami was over. The connection is broken and I have foam insulation. I’ve sent my email to Dustin but I wanted to hear from anyone about any solutions out there. I’m putting my trailer is storage this week and will deal with in the Spring. Appreciate it.
