ThetfordRV Tissue Digester, 19 oz - Thetford 15844

I’ve been using this for about 5 years. Won’t be without it.

paper towel got stuck but after i used this in one day next day i saw water went down but it still need some work done because mines is paper towel but this stuff is awsome! I recommend 10out of 10

Dumped 1/2 bottle of the stuff into an empty black water tank via toilet and filled tank almost full as the instructions call for . I used 'swizzle' stick hose extension to stir/wash the tank while filling it via a hose down the toilet. Couple of days later drove 75 miles to campground (hopefully to slosh it around good) before draining tank.The dump of the treated water did show it was 'dirty' water & not much/any paper, but the black water sensors are still clogged (still consistently shows 3/4ths full via lights on).Can't tell any difference in sensor behavior but tank drained pretty clean from what I can tell via back flushing, etc. Note: I also put 1/5 bottle down the grey water tank to flush it at the same time as its sensors are also not reading correct ... made no difference to those sensors either.Looks like I will have to try a grey/black water "Tank Blaster" treatment next.

We add some periodically during normal circumstances, and have used when developing a clog in the line/tank with good results.

My camper's toilet was clogging up weekly and I wasn't sure what to do. I tried this stuff, and after the very first treatment, my tank was running smoothly. I've never had a hint of a clogging issue since. Since then, i've been treating with this about once a month just as a preventative. I also started using aquachem and aquasoft toilet paper just in case. Once you've dealt with a few clogs, you realize that you never want to have one ever again.I highly recommend this stuff if you are having issues with clogging. It comes as a powder, so I typically pour a bit down the toilet and follow it with 5 gallons of water to mix it up. Hope this helps.

Definitely helped with tissue build up, but was hoping for healing with sensors

We have used this product for years and will continue to use it, as the results are worth the money. We use the same toilet paper in our RV as we do in our home. Using this product dissolves the paper into almost a liquid state, which makes dumping the black water tank effortless. Anyone who has ever used RV type toilet paper is soon looking for an alternative because RV TP is anything but soft and is practically see-thru. This product allows you to use your household TP and dissolves it as though you had used RV single ply TP. Use this product in conjunction with a black water tank treatment product and you cannot go wrong.

I use this Tissue Digester about every other month in our full time living RV. I do not buy that expensive RV tissue paper, hate that stuff. I buy only Charmin Super Soft, never had a clog nor any type of black tank issue.

Works great. I use it in my seasonal trailer. I have tried many products. I hate messing around with the toilet as probably everyone does. So when I found this it was great. Haven’t had any issues since I started using it. Definitely will continue to use this next year.

Clear blockages in one use.

Liked how it broke down the toilet paper

Good Price on Amazon

I bought 2 of these & both were opened (the safety seal missing) & the product was missing some powder. Used & didn't do anything. Looks like they replaced the product with jello powder.
