Unique Clear-It Liquid RV Black Tank Unclogger, 32 oz

Short and to the point answer, this stuff is awesome. Longer answer I bought my first fifth wheel from an old couple that had it sitting for a long time. Got to learn what a poo pyramid was for the first time, so that was fun! I tried everything. Every chemical I was told about, spray wands, several different auger. Man nothing worked. Saw a YouTube clip of a guy that said this product would work on most stubborn poo piles. So I bought several bottles. Pored one in and let it sit with an almost full tank for a week. That was about two months ago. Totally clear. Toilet flushes every time and no build up. Can’t believe it. So worth it.

This stuff really works. We had a compacted black tank so I poured the entire bottle in with 32 ounces of Calgon and another bottle of Calgon the next day. On day 3 everything had cleared out. Would definitely buy again.

No real smell, I can tell it has the potential to work well on some clogs because when I pulled the tank to empty it after it sat for two days I saw some of the build up actually come out. Unfortunately, now the toilet won’t even slow drain and we haven’t used it for over 3 days straight to let it go down.. and nothing. Water just sits there now. So essentially it’s made my clog worse. HOWEVER… it’s a clog we’ve been battling from poor maintenance by a previous owner and now I guess I have to pay for a plumber instead. I wouldn’t say don’t buy it. TRY IT! The price isn’t break your bank to see if this product works for you.. it just unfortunately made my issue way worse since it won’t drain at all anymore after I poured it in. I have a weird pyramid clog or something from the previous owners… and I’m a first time 5th wheel owner trying to figure this all out. End of the day. Try it and see, because I feel like if I bought new or better maintained used, I’d keep this brand and their products for maintenance… just maybe not a fix all for very stuck clogs.

My experience with Clear-out, is it needs two treatments to clear a clog in my black tank. I live in my trailer full time. Each treatment needs 48 hrs to work. So, times two applications, thats 4-5 days to wait. This time, I used Clear-out and let it work for 2.5 days. The clog was stubborn. I paired this treatment with a Camco’s Swivel Stick and wha-la, Im in business. *My new routine will be to close the tank, add Uniques Digest-it and dump 3-5 days later. Secondly, I’ll attach my Camco Swivel Stick to clean out debris. Repeat! I recommend this for clogs, but not alone. Last year when this happened, I called Unique and they generously sent me a second bottle of Clear-out free. So the company is solid, but with each application taking 48 hrs, thats 4 days with a full tank. I recommend Unique, but get a Camden Swivel Stick too.

This is the best stuff I’ve ever used. Poured the whole bottle into my black tank and 48 hours later it broke down the pyramid and emptied my tank. Highly recommend

Poo pyramid is causing me to empty black tank every 2 days. With 2 people using the potty. After watching comparison videos and reading reviews I decided to try this. I bought 2 bottles. I emptied my tank, poured an entire bottle in with water. It stayed in for 2 days. We were still using the potty. Emptied and used a swivel stick for 30 minutes. Closed the valve and put the entire 2nd bottle in. Both times with some water and continued use of potty. After the first bottle the gauge read 2/3 full. The second bottle stayed in a little over 2 days. We have to empty when full. The gauge still read 2/3. We emptied the tank. Put an entire 3rd bottle in. We got 2.5 days out of it and still read 2/3 full. We put an entire 4th bottle in and that lasted about 2.75 days and gauge still reads 2/3. We put a 5th bottle in. I'm hoping this will be in for 3 days. This is very slow to help break down the poo pyramid. It's very slow going to break down this poo pyramid we have. Is there a better product to clear a poo pyramid? It is obviously working well breaking down the new sewage.

Worked as advertised to unblock the rv black drain.

Ok

Worked like a charm. Our trailer sits all year round as we don't travel with it. We had a pyramid plug. We let it sit for 5 days and the clog is gone. Will probably do this again at the end of the season.

This was awsome it cleaned my tank perfectly. I always triple flush my tank after use, and this still removed alot. I left it for over 72h and had amazing results

Worked well for us. Made the hole down the middle of the clog it mentioned, added a bunch of water and added the Clear-It. Left it for 48 hours and it drained well. .ist came out on first release but I filled the tank and the rest came out in second release of the black tank valve.

It seems to have helped cleaning the sensors in the black water tank of our camping trailer. Previously, sensors were always indicating 3/4 full even if the tank was empty. I kept Clear-it in the tank with water for 4 full days. One day after I emptied the tank, sensors were back to one light only.

This worked great. We had a blockage and there was nothing coming out of our black tank. Put this in, filled with water and a few days later there was no more blockage and it emptied easily.
