Anti-flow Valve

[masterdrago]

Does our 2600RB have an anti backflush valve and where would I find it? On our previous 5r, I changed out the el-cheapo plastic one for a more robust brass model.

On which water line? If you have a black tank flush, there is one on that (usually behind the shower faucet).

Rob, I'm thinking the back-flow preventer valve for the black tank flush. It was easy to get to and replace on our Montana 3791RD. If I knew where the plumbing was for it, I could bypass it rather than replace it.

That would be in violation of code in a number of places.

How many number?

Rob, thanks anyway for trying to answer my original question. I appreciate your help.

Sometimes it is under the bathroom sink, other possible locations are behind the shower, usually accessible by removing the faucet assembly or a hidden panel on the opposite side of the shower wall.

Thanks, FT4NOW. On our Montana, it was above the black tank level in the rear of the vanity. I'll look for the access in the wall common to the shower. There is an access portal near the shower drain directly above the black tank, so I'll look there also.

The valve is behind the left side shower wall underneath the cubbie (where we store our towels).

Thanks. So behind the toilet?
