Sani tank flush

Hi all,
Anyone have an idea why the sani flush won't work? I have attached blackwater hose, opened lever, hooked up hose to the sani flush, turned water on but water doesn't seem to go in. I checked, the screen isn't plugged, stumped. Thanks for any ideas.

Hi and welcome to the forum.

The San T Flush usually has a check valve (often located at the hose connection) which commonly fails and produces the symptoms you describe. These valves are there to prevent any chance of black water flowing from the tank back into the park's fresh water system.

Sani flush

Our Sami flush is not working and someone posted a note about a check valve with a link to the company. It seems the company doesn't exist anymore.
Any suggestions on what to do?

If it's Swan Industries, maker of the San-T-Flush, here's their manufacturer website:

I've noticed that if you have too much pressure it won't work properly. I start with a low pressure and increase it gradually u til it stops, then back down again.

Was'nt the check valve; the holes in the tank sprayer were clogged with guess what..
Mine was removable at the black tank side. Cleaned it up and drilled out the nozzle holes a couple sizes larger. Siliconed back in; works fine.

I use mine regularly to keep the "you know what" from building up and clogging the system.
