Black water flush

[Jrenae]

We have brand new 2021 Salem 22RBS and found the black water flush is not working. After the black water is dumped and gray water dumped we tried to see if anything was coming out while hooked into the black water flush. Nothing....How can we fix this?

You will have to find your anti-siphon valve and see if installed backwards. See thread below.

Most common problem is the back flow device. A lot of threads on this (apparently) typical problem with new RV's and TT's. A quick read:
