    Just perfect!
  

*by M***. on Reviewed in the United States on May 29, 2015*

Finally a usefull product to automatically Top Up your cistern and  your rainwater tank with water.Simple and easy to use.Tip! Before using this unit. I suggest you flush out the pipe line you plan to connect with this unit.If you can invest and add a prefilter like a micron filter in your water line thats the best. This will help you lower the maintenace of the unit.It will prevent small particles from cloging the mechanism inside.I had to learn the hard way when i found out my water pipe line had some sand like particles the unit started to drip even if the level was up. In any event i discovered this unit is design to be serviced. You can clean the inside by twisiting it slowly to remove any small particles. All you need are two large wrenches and you can easily losen the bulkhead and manualy turn it. I give this product design a perfect score!
