Wildcat Black Tank Vacuum Breaker/Check Valve Location

[bword89]

It may be in here and I haven’t found it but was wondering if anyone could tell me where the check valve is on a 2017 wildcat 28sgx when I hook up to my black tank flush I can’t get any water to go in

On my 32WB the valve is behind the shower hot and cold valves.

That's where mine is on my 2015 295RSX. At least, it sounds like that's where it is. I haven't had to get eyes on it.

While looking for ways to run solar controller wires I found the vacuum break for the black tank flush behind the shower valves.

Mine is in the toilet room just below the storage cabinet behind a panel screwed to the back of the lower cabinet held on by screws it is almost impossible to remove panel I have found and when I finally got it out noticed the accessory control panel is on the other side just above the valve. I keep my fingers crossed it never leaks as I'm sure it would wipe it out.

low water pressure wont let it flush.

In our 2016 262RGX the vacuum breaker/check valve is in the bathroom sink vanity behind the faucet plumbing. I have replaced mine with brass check valve and vacuum breaker units.

Ok guys just a little update/question the breaker is behind my shower controls and when I got to the breaker it was installed backwards so I assume that is the reason it won’t work but when you look on the top of the breaker it says this side up but the way it needs to be installed the top will be kinda sideways when the water starts flowing will it completely seal or does it really need to be upright

It needs to be upright

The check valve portion is on the output side and is a spring loaded ball valve and not affected by orientation. However; the input side does have a disk that rises to seal off the vacuum breaker portion (top) of the valve when pressure is applied and when the pressure is removed the vacuum opening to ambient allows the disk to fall back down sealing the input port. Off kilter may or may not have any affect on the operation of the valve but it would depend on how far from vertical it is. Hook it up and check the operation but have someone standing by to let you know if it leaks with pressure applied. Remember that when pressure is removed some residual water will drain back out of the input plumbing as the vacuum portion disk settles back to seal off the input port and that is normal. The output port will have already been sealed when the pressure was removed.
