We have a 2006, 36', Class A Coachmen Aurora MH. This week our grey tank drain became plugged and what I was able to remove from the drain was a rather large clump of white, slimy plastic (like a sheet of thin plastic, at least a very large handful). I used a drain snake to help get the clump moving further down the drain pipe and finally the water pressure above it helped push it out. I looked and looked on the internet to see if anyone else had such a problem (no luck) and if these grey tanks ever have a liner put inside them (doesn't make any sense to me, just waste water). We had this coach for 10 yrs. and never had any issues with either of the holding tanks. I'm concerned there could be more of this junk in the tank just waiting to plug the drain again.
Any ideas what this may have been? Manufacturer issue???
Thanks for any help.

We had not opened the black tank valve yet. We keep it closed until it is either getting full or we are ready to hit the road, then flush with water from grey tank. Not saying both grey and black vales haven't been open at the same time in the past but not on this trip. Thanks for your replies.

Grand kids. Other than that, we be at it since 75 and never ran across anything like it. Your couch is newer so maybe some one else will ring in.

Easy to explain if it was in the black tank. Being in the grey tank probably means it came from the factory. I guess there is a possibility of transfer if both grey and black valves were open at the same time. Some people have done that to transfer waste from the full tank to the less full tank when out in the boonies. If it came from the black tank originally it could be anything that went down the toilet accidentally.

Builders have been known to push/drop debris into mostly the black tank, but I can see it happening on gray.

One CEO got a package in the mail
What the customer fished OUT of the black tank.
(Double sealed before mailing of course)


Home was where I park it. but alas the.

A cut out disc would have remained rigid rather than a slimy plastic clump.

15 yrs a disc would be a very slimy piece of plastic

I guess by that logic, the 15 year old tank that the supposed disc was cut out of, and made from the same material, would also be a slimy mess. I think he would have described it as a round disc rather than a large handful/clump.
