A 32 Deuce,
I thank again for your response, I tried to refill the holding tank by pouring 5 gal. buckets 1 at a time to see what capacity is on the grey tank, after 4 buckets the shower backed up when trying to add the 5th bucket. You reponded to me on the plumbing thread on the acorn clog followed your suggestions to no avail also removed the entire sewer valve assembly to grey valve backflushed and snaked and flushed water through system, no more debris came out. Have been trying to solve this problem since Jan. 5th My wife and I dry camp quite a bit and know that will not be possible until I know we can hold full capacity to be able to stay 5 or 6 days. 20 gallons can fill up in 2 to 3 days if using the shower much.
