David, you can do just what you said; cut it out and install at the inlet. In this case, I'm referring to one of the brass inline type from Lowes or Home Depot. Very small screw on type. The black flush is a stand alone system. You can put one at the inlet. They are required to put it at / above the toilet level, which is why you see it where it is. I don't agree that an external has to be the same height as the toilet. As long as the inlet and anti-siphon is above the black tank level, you should be fine. Most inlets are installed a few feet above tank level anyway. On the No Fuss Flush system, it's practically mounted at the same level, so that can be left to another argument. It'll be your decision in the end, and you'll get varying opinions.

As long as we keep buying RV's, I will keep cutting them out. Just one less leak to worry about in a place that can cause a lot of damage.

At least in Heaven, RVs will be perfect, and I won't have to keep fixing them.

Here's the Camco tornado flush.

It comes with the vacuum breaker (although in the pic, it looks more like a check valve to me), even though it's external. You don't want nasty water going backwards into anything (in this case, it could go back into the CG supply).

So y'all cut it out and cap the line under the sink? Mine is under the sink in the master bath as well on my 36 QBOK

No,leave the lines in the (Upper) position just remove the (Plastic POS valve) and connect the line together with proper fittings. Them use a (anti valve on the outside inlet for B/T rinse)!

We have a 2012 Sabre 32RCTS and our valve is in the linen closet in the bathroom. Ours leaked real bad and water drained out of the cabinet right down onto the furnace, We thought we blew the control board on the furnace but it worked ok after drying out. We replaced the plastic valve with a brass one. Here's a link the the site we bought it from.

Thanks for all the input. Quite an education. I took the valve out and looked it over and than put it back in. I isolated the connection and put a bucked under it. I want to make sure that is my problem. I flushed yesterday morning, drove 200 miles, set back up and so far no issues. I picked up a couple of PVC fitting to bypass the valve and a vacuum break for the end of the hose. Even if it doesn't leak I think I will do as suggested for the short term and when I get home in September I will do a more permanent job of connecting the lines or I might just leave as is and put the valve back in if I ever sell the unit. One less liability issue.

Thanks again. I will update and let yo know if the valve leaks again.
