This product works and fills up to the same spot on the tube every time. The problem is that it takes way too much water level drop to reactivate this thing. My stop point is about 2 1/2" up the tube, and it will not reactivate until the tube literally comes completely out of the water. In my sump, that equates to almost 10 gallons of evaporation before the thing activates again. That is enough to cause my salt levels to rise from 1.026 to 1.028. It basically comes on every 4 1/2 days for me.
I think I am going to cap off a piece of 1" pvc, drill a hole to fit the sensor tube into, seal it off, and use it that way. The additional air and water surface area trying to rise up the larger pvc tube will cause a higher pressure gradient when the water level changes. I may just not use their air tube at all and make my own pvc tube with air line to the pressure switch.Hide
This is the perfect solution for people that use a small pump to move their RO/DI water from a storage container to their main tank. The controller switch itself is a little difficult to dial in, but once it's in place, it works well.
Purchased this based on other reviews and have watched the level drop a full inch and so far, nothing. Also, I did not receive a new product as pictured on the website. What I received was already assembled in plain plastic bag with no instructions. A bit disappointing.
This product has been working exactly as advertised for a few weeks. I am using it to control the daily transfer of top off water from one container to another. I set it up in about 5 minutes.

This product has been working exactly as advertised for a few weeks. I am using it to control the daily transfer of top off water from one container to another. I set it up in about 5 minutes. I switched over to magnetic holders for the tube to make sure it wouldn't come loose and I use a timer as a backup to avoid a potential flood. The only minor detail is you need some way to mount the black box (I'm using velcro).Hide
