1st Timer/Black water flush trouble

[MontanaSteve]

Hello all!
Just upgraded from a 92 pop up to a 2018 SLX 224. Maiden voyage over the 4th..Loved the trip, hauls easy behind the Tundra. BUT..when we hooked up at the dump station had a surprise..turned on the hose for the black tank flush and had fresh water running out from somewhere over the tires ..and found it sprayed the cabin too. Can't find the reason or the leak.
ANY IDEAS ?

Check the anti-siphon valve for the black tank flush. It may be the problem.

Welcome to the forum.

The black tank flush line has an anti-siphon valve that causes problems for some folks. Mine is under the bathroom sink. That's all I got. It's an easy fix. I hope that's your problem! Good luck

Had the same problem, went to my dealer under warranty. It was the vacuum check valve right inside the trailer wall behind the black water flush hookup. In my trailer it's in the back of the bathroom vanity. Dealer replaced it in about 5 minutes, said they go bad often enough that he keeps a supply in stock.

Found the valve..water poured out the top of it when I attached the hose. THANKS for the direction. ordered 2. one for backup.
