Walex Commando RV Black Holding Tank & Sensor Cleaner - Eliminates Waste & Pa...

Our sensor quit working g and this helped clean it off and works great

So we bought a travel trailer third-hand. We believe the black water tank was emptied before it sat up for the past year, but not cleaned out in any way. So we've been having to force down waste for a couple weeks. I searched online for a solution because the regular black water tank treatments meant to dissolve current waste and toilet paper weren't helping at all. I used a method described by others online, putting hot water with dishwashing liquid into the tank. I even added baking soda for some softening and slip. That caused a rush of gunk to flow out and resulted in a really awful stench (I guess it got some of that old stuff moving!), but still stuff was clogging near the top. Maybe doing it again would have helped more, but I went ahead and bought this product after reading the good reviews. Well, we emptied the tank again (or so we thought) before replacing the toilet. After removing the old toilet, we realized the tank was clogged again and the waste was almost to the top. I opened a Commando packet and poured it right in. I cleaned up where the old toilet sat, my husband installed the new one, and I checked the sewage level with every flush expecting that at some point it would go down. About 6 hours later, I noted that the level had gone down some. It was still pretty high up, but that was progress, and I knew it would take longer. Well, I just checked again. It's been 20 hours since I poured the packet in and I was shocked to find that not only is the waste too far down for me to see it anymore, but I can see sunlight coming in through the tank walls. I don't see one bit of gunk stuck on it either and the stench is gone. My gosh, this stuff really works, and it only took one application. Keep in mind that we throw away most of the toilet paper (all from #1 but not #2), so it's not overburdened with toilet paper--at least not from us. Expecting more of an issue, I actually bought the bucket of 40 packets and I was expecting to use one a week. I'll see how it goes, but I may not actually need this many after all. I do not regret the purchase at all though.

Have used this product several times as directed and it seems to help clear the black tank, but not completely. It could be a bad or stuck sensor that will not clear.

Worked as described! Black tank in my 2012 5th wheel camper always showed full. I filled the tank up with water and dropped one packet in the toilet. Waited 5 days and drained it out. BOOM now my tank sensor is reading empty and seems to be working great! Definitely worth the money!

Worked as advertised on black water tank. Gauges started acting wonky, added product, drove to next campground, voila, gauges now working well!

We always had trouble w/the accuracy of our black water holding tank in our RV. It would read empty after flushing it, then on arriving home it would read 1/3 full. We heard that stuff can get attached to the sensors inside the tank and no matter how we good we flushed it out it would never read accurately. We decided to try this product and my husband let it sit in the tank for several days. Immediately after flushing it all out the tank read empty and stayed on empty. We thought this fixed the problem. Well.... it did but not for long. The next time we camped we ran into the same problem, reading empty after the flush at the campground, but then reading 1/3 full after we arrived home. My husband did another application of this product and it fixed the problem again, and the tank read empty and stayed reading empty. So.... we have decided that this product does what it is supposed to do as long as you use it after every use. But this could get a little expensive. The company sends you 4 packets (a years supply), so their intent is not for it to be used after every trip. Don't think we will buy it again.

We used this product after a year of black tank readings indicating full after emptying. It cleaned out the tank and sensors now indicate empty!

Brought more than once

Good product, does exactly what it says on the tin

is what it means

Despite using tank cleaning drop-ins regularly and using the tank flush, we would consistently a 1/3 full reading immediately after emptying. We dropped one of these into the tank, filled per instructions and let the solution sit for approximately 12 hours. Emptied and tank flushed again and after a moment or two, the tank indicated as empty so it worked perfectly! The only think I wish is that these RV necessities would be less costly - on a cost per use basis, we are paying just over $4 per drop-in (after tax). True, you shouldn't need to use them very often but that's still a lot. They do work though, so I guess my mindset should be that you get what you pay for.
