Triple shine getting into hot water line

[stampedecarwash]

Over the last day or so I’ve noticed that one of the lines going from the hot water tank to one of the triple shine hydro minders has been filling back up with chemical and is seemingly trying to return to the hot water tank. The foot valve in the hot water tank has been doing its job and keeping it from coming back and mixing into the hot water. I’ve replaced the foot valve just in case, and made sure each connection is secured. There are no obvious signs of a leak in this particular line. I’m just wondering if anyone else has had a similar experience, and possible solutions or if I’m just overlooking something.

I have added in line PVC check valves to all my trifoam setups. You can put them close to the injectors and are easy to replace. Hose barb fittings on each end.

Foot valve should prevent that. Make sure your hydrominder discharge hose has a small hole drilled into it to break the siphon.

You don't have to run that hose back to the hot water tank, you can draw directly from the solution tank and adjust tips accordingly.
