Valterra A70 No-Fuss Flush with Check Valve , Yellow

Worked well, was easy to install for my 2013 Salem Travel Trailer. The factory clean out connection cracked and was leaking black water. Used a 1 1/4 hole saw to drill out the old plug and installed this in the hole. Be sure to use a good sander and clean up surface wipe with alcohol and plenty of silicone sealant. I attached to the existing trailer clean out Pex line. 1/2 inch drop line slipped right over and connection was quick and easy. Works just like new and no leaks after a couple weeks of the tank sitting full.

Installed on RV that did not have Black flush from the factory. I installed 2 one on Black and one on Gray tank. They are fairly easy to install and work great.

Let me start off by saying this probably is the best rinser for your holding tank there is. But there is a caveat. This is really a five star product, but I did knocked off a star because I had to alter it, and this should have simply been done at the factory.Know that anyone who has ever dealt with a black tank understands that it is probably his/her least favorite thing in the world to have to deal with. The last thing you want is any kind of leak.So out of the box, and as so many other people have said, this thing will very likely leak and leak bad on you.You can fix and prevent this though very easily.Do yourself a favor, and before you install it use a 9 mm hex key and remove the inside valve. It is self-explanatory and very easy to do.You may even notice that yours is loose to start off with, as mine, and so many others, were.Simply unscrew that unit, wrap a bit of Teflon tape around the threads, and then screw it back in.I had to do this after the fact, and it was still very easy, it is just even easier to do it before you install the unit.Before I did this, mine leaked horribly bad from behind the white unit, that is to say the side opposite of where the hose goes in.That told me that the unit itself was leaking, and as soon as I took it apart, I understood why.The internal valve that you are removing will seat itself against the plastic of the body, not unlike the angled seat of an lp valve, but there is very little to prevent it from backing out. By adding the Teflon tape, you are in essence adding something that will prevent the unit from backing out overtime, which is very likely being that this is intended for use in an RV, and it will also prevent any leaks.As soon as I did this, I went from a completely unusable unit, to a completely leak free unit.With my install, I used half inch pex to a male hose thread, shark bite, 90° valve. I didn’t really want the ability to turn it off, but in terms of checking for leaks, this turned out to be very beneficial. Once I plumbed it, I simply turned off the valve, which let me check the pex for leaks, there was none, so I was good there. As soon as I turned on the valve, the unit itself leaked like a sieve. It was at that point that I backed out the internal part of the unit using the 9 mm hex key, added the Teflon tape, and reinstalled it. Voilà, a completely leak free installation.

This works great and saves me time. I used to use a pvc pipe and put it down the toilet to clean out the black tank. I always felt bad when people were behind me at the dump station. I was in and out of the camper.I drilled a hole in the black tank used silicone to seal and ran a short piece of hose to the side of the camper. I put a on/off and quick connect on it as well. I just connect the hose turn on and your done.I has a good pattern and works well. I have a translucent 90degree at the end of the sewer hose to tell me when the tank and the hose are clean. Clear at the trailer will only tell you the tank is clean.great product if your trailer didn't have a flush installed from the dealer.

Black tank flush.

Works great for tank flushing, but I did deal with some trial and error before getting it all good to go. I also ordered the assembly kit, which is where I ran into trouble. The small jet size on this nozzle create a good amount of back pressure on the hose/fittings. After going through two different sets of plastic fittings (the Valterra assembly kit ones, plus a hardware store garden hose set) and having major leakage issues with both, I finally got smart and picked up solid brass fittings from the plumbing department. The plastic fittings leaked so badly that the nozzle was basically useless. Now that I've got it all set with brass, it works perfectly.

This is nice in theory, flushes the tank good and is water tight for the poo water..... But when you go to flush, the clear water leaks like crazy. Changing fittings, no Teflon tape, Teflon tape, tight, or lose it leaks like crazy.Amazon is sending a replacement, Let's see if it works.Update replacement leaks just as bad if not worse, have the fittings tight, loose, with teflon tape, without it, hand tight, wrench tight. No matter what it leaks a steady stream.

I installed this a few months back when it was cold and after we had winterized. I finally got around to testing it earlier in the week and, like some others here have commented, it leaked badly. Really badly. So much so that I would have refused to use it anywhere in public given the way some people react when they see any kind of leaking coming from an RV - especially if you're at a dump station. Some here said that it seemed to be leaking from where the hose-thread coupler (white in my picture) mated with the black body, indicating that it was loose. When I put mine under pressure, however, the water seemed to be coming out of the body. I also noted that it seemed like the black piece going into the tank through the black plastic flange seemed loose. It turns out, it was loose. There's an insert that threads into the body of the sprayer. Mine was loose and water was leaking back out through the loose threads. Using a 9mm hex wrench, back the insert out and give it a couple of wraps of teflon tape. Then snug it back in so it has a few foot-pounds of torque on it - not too tight because you don't want to strip the plastic threads. Making sure that the rubber garden hose gasket is installed (not seen in my picture), thread your hose connection on well and, if done right, it won't leak when you turn the hose on.

Merci

Unit was the same as we removed but the fittings are designed for a garden hose. Because of that an additional fitting purchase was necessary to match up with the existing hose.

installed in MotorHome and works great .........
