Unique Clear-It RV Toilet & Black Tank Unclogger Liquid, Breaks Through Pyramid Plugs & Clogged Pipes, RV Tank Cleaner, 32 oz

one bottle of this product fixed a problem that had been getting worse for months. I left it in for 40 hours and problem solved! just follow the directions and hopefully you will have the same result. when I filled and emptied the black tank for the second time what came out was not quite clear but a huge Improvement. I highly recommend this product and if it is ever necessary I will purchase it again.

did exactly what it says it would worked amazing on my used camper i just purchased the previous owners neglected the black tank and this brought it back to life. note i did leave it in a full black tank for a week.

The RV toilet is very badly clogged with stool. Should have started with this product. For the first time in a couple weeks after about three days stepped on the flush the liquid drained. The black tank had stopped draining. This time it drained quite a bit. But it is again not draining when I flush. I will order another bottle and meanwhile I will keep trying snake. The snake I believe helped open it up so clear could work.

This stuff is awesome!!!! Worked Iike a charm.

if you need this product, IT WORKS

The company unique is awesome and they've been really good to me.

Poured into a clogged tank. Left it alone for 3 days and when I opened the valve, nothing happened. No satisfying sound of rushing liquids lol. Went to bed super bummed, I had forgot to close the valve that night and when I woke up, my tank and toilet were completely empty!! Flushed tanks without a problem immediately. Super surprised and happy with this product!!

I don't dislike thus item. It will more likely thzt I wilk purchase another bottle.

i didn't order this item. That's why I put low numbers Otherwise I say your response is very good

Followed instructions exactly. Waited even longer than was suggested. Didn't work at all, still have a disgusting blocked black water tank! very disappointed!!
