Kalk Reactor Problem

[Shadowramy]

I currently have a kalk reactor that is hooked up to a dosing pump which is hooked up to a 30 gallon rubbermaid tub - which the doser is hooked up to a ATO unit.

Problem is, when the sump water lowers it triggers the dosing pump to pull water from the rubbermaid tub to the kalk reactor which fills the sump. However, after the water level has been achieved, the doser stops but the kalk reactor continues to "drip" kalk in. I have tried raising the tubing above the kalk reactor then down to the sump but it still continues to drip - a check valve will not work since it is not back-syphining.

Any advise?

Try running the output from the Kalkreactor to the tank or the tank overflow instead of the sump.

Is dripping because of preassure, how long does it ontinue to drip for after the pump shuts off?

It's a small siphon that continues to pull water through the system. What I do is put a 'T' inline, usually right after the pump (in your case before the dosing pump), and run an air line straight up. When the pump shuts off, the siphon will suck air and break, stopping the dripping.

skewch, that was what I was thinking.

Also apprentice has a nice idea since the tank would be higher than the sump.
