calcium reactor ato unit

[erictorres0311]

I am in need of a new check valve ... anyone know where I can get one? or other after market part I could use?

It is the one that separates the ato line and the calcium reactor.
I have tried cleaning mine already and water still drains back into the reservoir container

Any airline type check valve will work but the life is fairly short. You can order the correct one here, basically expect 6-12 months from a standard airline check valve, ours should last 2-3 years provided it is installed so it is looped above the reactor as shown in the manual.

Stupid question ... Does it have to be a check valve specifically for water ? Or can it be a check valve from like an air pump ?

It can be an airline check valve, but the life is very short, airline check valves usually have either a rubber duckbill which hardens in the high pH of kalkwasser so after 3-6 months they don't close all the way, or they use a stainless spring and ball, unfortunately these are made in china of low quality materials so they rust. We used to use these types and they never last more than a year. Our check valve uses a nitrile seal and US made 302 stainless spring and ball, they are designated as moderately resistant to Calcium Hydroxide, which per the specs means that unless the solution is heated or supersaturated, it should last 2+ years.

The one I have had been used for about two months .... ISO have a loop is there a specific way or height? You have the manual any chance

You can download the manual here, new it came with a short piece of tube and a cable tie, you attach the short tube to the bottom and the check valve to this and this is cable tied so it is above the reactor. If it is not done this way, powder can get into the valve and jam it open, in general with a syringe you can flush this out and repair it.
