Hydrominder is back feeding

[Knight01]

My presoak is pulling water back into the Chem tube. We've taken it apart and cleaned everything but it is still backwashing.

Tips,tricks or ideas?

do you have a foot valve on the line that draws the chemical?

Drill or cut a hole in the discharge hose coming out of the Hydrominder just about the level of your holding tank. This will prevent any siphoning from the Presoak tank back the the chemical container.

I do have a foot valve.

Thanks Randy thst stopped the siphoning, but now the chemical is not flowing up. Could that be a bad foot valve?

Where did you drill a hole or cut a notch in the hose? The hole has to be in the short hose that comes off the Hydrominder. You could have a bad foot valve on the supply line.

The foot valve is bad. It caused the initial problem. The hole in the discharge hose stopped the symptom, but the foot valve is still bad.

Drilled a small hole on the hose that has the presoak mixed with water going into the tank. About an inch or so below the top of the holding tank.

I took the foot valve off and it did not appear clogged or broken, what causes them to go 'bad'? It looks like a pretty simple filter device.

Chemical incompatibility with the foot valve is the most common reason a foot valve goes bad. Presoak would work best with a foot valve with viton components.

Beautiful that's where you want to drill the hole.

I stopped using the Blue Hydro systems foot valve and started using the DEMA 100.11 foot valve. They seem to last a lot longer. https://www.kleen-ritecorp.com/p-65...e-fits-1-4-inch-3-8-inch-1-2-inch-tubing.aspx

Somethings if you flush the foot valve out backwards with hot water you can a little more life out of it.
