Detergent draw tube is allowing liquid to flow back

Is this while you are cleaning, or when the machine is off?

Fresh water tank on board?

Do you have a Dwyer meter in your chemical injection setup?

Shake the valve and bang it against the jug, then stick it back in. make sure that the hose just has the valve at the bottom of the jug and it is not curled up with the check valve laying down, or upside down. Mine sticks every once in a while, and following what I wrote above, it does not stick so much.

The check valves are sticking oh round one. Clean them out and you should be good to go.

Ruptured diaphragm, if you have that type of chem system

Danny;

You need to tell us more about the system you have.

A check valve should only allow flow in one direction, usually noted by an arrow.

I have a Cemtex & no fresh water tank & sometimes have this problem. To solve my problem I have to turn down incoming water pressure regulator.
