Q
Will this pump prevent siphoning
My ro container is above my sump, I'm loo king for a pump that won't siphon once the water is topped off. Will this work?

No it will still siphon, Easy fix is to put your tubing higher than the top off water container, (so run your tubing up higher than that then bring it down from there where you want it. This pump has been great for me , with the tunze ATO.

REVIEW
I bought new pump only as back up since old one was 6+ years old. I now use new pump (and use older one as back if main one would go down). It is a bit noisy, but it only goes off few times/day.

Bought this one to replace 3 year old pump that I use for ATO with Kalk. Old one stopped working, or so I thought. Just soaked in vinegar and it works great! Now I have a spare just in case.

It’s nice that this pump is offered as a replacement. I have two of these top off units and the replacement pump’s are vital. Great little pumps I have run them dry several times and they continue to work. Always nice to have an extra on hand.

REVIEW
While the Osmolator is a great product, the metering pump has caused me several issues over the years: such as stopping to work randomly, melting due to lack of water in the container (this is supposed to not happen), problems with air bubbles when it is first started, problems if there is little wa...Read More
