Calcium osmolator issue

[hredder]

Hey Roger,

Got my pump about 2 weeks ago. THis is probably a user error on my part so i just want to pass a few things by you since the directions for the pump can be a bit confusing especially if this is your first time. Just to make sure, the tubing with the non return valve goes on the botton of the calcium dispenser which i purchased and the tube that feeds directly to my sump goes to the outflow on the top of the calcium dispenser. Im assuming I set this up correctly. Secondly, ever week I should dump the water thats in the calcium dispenser, put a few teaspons of kalk back in and fill the entire thing with RO water, let it sit for 30 minutes then turn on the osmolator. What im finding is since i shut my osmolator off since i ran out of RO in the bucket the water level in the sump went down. When i turn the osmolator back on, the sensor doesnt recognize that the water level is below it and to turn on. I have to get some wave action in the sump. Im assuming if the sensor is in air and there is no optical interference, the sensor cant react to turn on the pump. Is my assumption correct? When the pump does turn on, it turns on for a minute but no water pumps out. I turned the pump over to get the air out of it and I can feel it drawing in water, but on top of the calcium dispenser there is still some air and there is no water exiting the tube that goes into the sump.

I hate to overload with questions, but your the expert in this field. Before I add kalk to the dispenser each week should i dump the ro water in the dispenser or can i just add it to the water thats already in there from the previous week?

I appreciate any assistance you can offer me

When I first hooked up my calcium dispenser, I had that check valve going backwards and had the same "symptoms" as you. Pump is running but no water comes out. I had even blew through the valve before hooking it up to see what way it went...still had it wrong. Be careful if you turn it around, I broke mine trying to get the rubber tubing off and now have to wait for a replacement.

The check valve should be connected to the inlet but it should be above the dispenser and secured to the output line at the top of the dispenser using the zip tie that was included, this is shown in the illustrations in the manual. This takes a lot of the strain off the check valve which will be damaged by constant exposure to kalk powder.

You can just add more powder, I just stick a couple fingers in it to displace some water and then make a paper funnel and add the powder. I would only dump the dispenser and give it a full cleaning every 4-8 weeks.

If you are dosing the kalk into the sump near the sensor it will form a film on the sensor and then the sensor is basically blind and thinks the film is water. To solve this soak the sensor in vinegar and move the top off hose down stream.
