Question: would flushing before detaching the tank prevent the blowback problem? what solves it?
Document: It worked great. We took it camping this weekend and it did what was expected with no problem of it working correctly.
It is all it said it would be. Very pleased with the productBigger than I expected from the pictures
Would order from this company again. Product works great, we have it on our boat, it serves it's purpose. But it's a toilet what more can you say.
For the price this unit is a great buy. I used it one weekend and it served it's purpose very well. Would recommendthis to anyone.
Great except the lever gets hard to pull out after a while. Would think it would get looser as you use it more. Seals good. No spills.
We have not used this yet...but, I believe it will do it's job. Another great product!It would be great not only for camping, but whenever you are somewhere where thereisn't no restrooms or out in no where land. Another great invention!! !
I have had the same model on my boat for many years and it worked great. I thought this would be the same, but it only LOOKS the same. It is a cheap Chinese knock-off. It even feels lighter. The seat hinge broke off, and the worst part is the seals on the slider valve leaked out waste. Had the unit for less than two months! $80.00 in the dumpster!
We ordered the 5 gal. camp toilet and received it in excellent condition. I give this camp toilet  4 stars only because I think that if it had a pour spout to aid in  emptying  that it would make this chore somewhat easier. We were still able to empty and clean out this unit at the campground dump station without too much mess.
works perfectly for our tent, love it, no more getting out at night to use bathroom...compact, easy to clean up
Worked like it was supposed to. One draw back was I filled the resovoir to the top. When I got it into the tent, I found out it was leaking from the bellows (flush pump). I had to lower the water level to keep it from leaking.
Answer: no
