Unclog and Break Through Pyramid Plugs with 32 oz. Unique Tank Cleaner Liquid for RV and Boat Black Holding Tanks - Product Code 41H-1 Review

This stuff is great. We found out about this product from YouTube. I Love RV Life tested this product and we were impressed. We put it in gray and black tanks. It works perfectly. This thing even takes toilet paper in a black tank.

Okay, this is technically made for black water tanks, but my ex didn't use the gray water tank properly, so mine is full of sediment. I put this in my gray water tank and left it Friday night through Monday night and oh my god what happened. Several days have passed and something comes out of every empty one.

I was very disappointed that it didn't work. My toilet tank was clogged badly, when I try to empty it only a trickle comes out even if I pour it through the inside of the toilet. I was really hoping this would work. I left it on for 24 hours thinking maybe it would at least partially clear it up. Nada. I'm glad it's worked for others, but I seem to have a very difficult block.

This product was amazing. This eliminated a very serious pyramid plug that was stuck due to a leaking black water valve.

I highly recommend this product as a first try if you have a clogged black tank or even your black tank is slowly draining. I also bought a digestive…

Contacted the seller and he refunded me the money I paid for the purchase. I bought it again as it is the only supplement that has even started showing results. The seller also gave me a number to call if I needed help clearing my blockage. I think the second dose will do. I have the mother of all blockages and I believe this product will work on the vast majority of blockages the first time (although late updated). The second round completely cleared the blockade. I could use my black tank to…

For some reason, after more than 10 years of continuous operation in a mobile home, the consumption of the black sprayer suddenly fell drastically. I checked that the reflux value works fine and the problem must be clogged atomizers in the tank. The mouthwash didn't help at all. Air pressure (over 100psi) didn't help. Long soaking in clean water did not help. I've had 2 treatments with this product and at least 1 more with vinegar (2.5 gallons of 6% in a 40 gallon tank). Each treatment helped…
