It seemed that no matter how many times I E-Z Flushed the black tank, I could still see paper coming out in the clear Hydro Flush attachment. After one treatment I could see no more paper being flushed, and the sensors on our 5th wheel's empty black holding tank actually read empty for the first time in almost 2 years! I used it in conjunction with Thetford's Level Gauge Cleaner (instructions on both said this was allowable). Both are dry granules, not liquid, and the instructions suggest you fill the tank, add the treatment then drive or move the vehicle to mix. This is not easy on the 5th wheel in its storage location at our home. I decided to use the E-Z Flush to fill and mix the treatment in the tank. Thetford's instructions should warn that this will cause bubbles and foam similar to laundry detergent that will percolate out the Vent pipe on the roof (and toilet, if you open the flush gate valve) when the tank fills to capacity. Not a major problem, but a surprise that I just had to laugh about. It is not often that I can say a product works as easily and effectively as advertised. So much easier and cheaper than removing and replacing the sensors! These two products will be on my post-season winterization check-list from now on.

My wife and I both use standard household toilet paper (Charmin) in our RV without any issues simply by adding this tissue digester. This product turns the tissue paper into a fine almost shredded form, which makes the trip to the dump station quick and easy. To achieve the best performance, ensure you have plenty of water in your holding tank during the trip to the dump station – the longer the trip the better it works. I would recommend this product to all RV users who don’t like to use one-ply toilet tissue.

We used this product after having a build up of tissue. Worked perfectly and our tank was cleaned out. Think we wil use on a regular basis to prevent the problem.
