Video Transcript for Valterra Bladex RV Waste Valve Seals Review

Adam: What's going on everybody Adam here with etrailer. Today we're going to be taking a look at the Valterra waste valve seal kit. So if you have a one and a half inch diameter valve for your gray water tank, we have the replacement seals and it comes with the hardware. So this is just going to be an easier fix than just replacing the whole entire valve. It's just going to stop your leaks from happening. So first things first, we need to remove our valve and to do that we're just going to need a three eights inch wrench and socket to loosen these up.So we had a little bit of an issue.

Another reason why we're kind of switching this out. All of our heads on our bolts snapped off. But what I'm going to do is go ahead, just take a little punch. You can take anything that's going to fit in that hole and just give it a good little tap and it's going to break loose real easy, ideally. Look at that.

Look at that. Oh yeah. So I'm going to do that for all of them and then we can go ahead and take this valve out.So when we're going to be replacing our seals, the nice thing about it is when we do get the seals, we don't have to drive these back in. Obviously these are completely unusable because they're all seized up and stuff. So I'm going to get those out later, but now the nice thing is our seals are bad, but we can replace them really easily and it does come with the hardware so we can replace both of them all in one go around, which is nice.

So all you really need to do is take the new seals, just put them in there. I mean, it's really, really that easy.And it's going to be the same exact thing for the front and the back and check that out. Pretty much done deal. So everything's really working fine. I didn't have any leakage or anything like that.

So I can just go ahead and use the new hardware to re-install this valve. So now with all of our new stuff, shouldn't have any leaks or anything like that. Line it all up. Oh yeah. And put our hardware through just how it was before, just new stuff. And what I like to do is put them all in, get them all lined up, and then I like to go through there and tighten them all down separately, but kind of going from one to the other. So meaning I'll put this nut on here, I'll kind of tighten it down almost to the bracket there, and then I'll do like a star pattern.So I'll tighten this one down, then this one down, then this one, then this one, that way we're not going to be putting that seal under any weird angle. It's not going to get smushed. It'll just help everything go nice and smooth. So with the new hardware, we are going to have to have a eight mill and a 10 mill, whichever kind of tools you need to get it done. I'm just using a wrench and a socket. But go ahead and I'm going to tighten one up, not all the way, and then tighten the one back here up in that star pattern. Kind of like the lug nuts on your truck, car, motor home.Now that everything is all secured down, the levers moving, there's a little bit more of a seal there, and we don't have any drippage coming out from underneath. So everything's nice and sealed up and now we're good. Well everyone, that just about does it for a look at the Valterra replacement seals for your inch and a half diameter gray water tank waste valve.

Replaces the seals and hardware for your 3" Bladex waste valves. Seals, nuts, and bolts included.


I needed a replacement seal for my Bladex valve for my black tank. There were two parts listed and I didn't know which one I needed. I asked for Lori because she has been very helpful on several orders I placed before. She was able to determine that because of the year of my Casita, I probably needed the earlier style seals. She was right! I have installed the seals and the slow drip has gone away. Thank you, Lori.

After a year and nearly 2000 miles with many operations of the black tank valve with the new seals, Ive had no more problems with leaks.

Arrived promptly. Easy to install. Happy Camper.


These have worked great for me.


The seal kit worked well. I used it as a maintenance step. The valve is in the dump line. I was upgrading the other valves so this was a natural.

Glad I put in the new seals. Valve still working smooth. love it.
