A submersible rain mains changeover pump system is similar to our external rain mains changeover pump systems, but it can be submerged in your tank. It is a great choice when connecting your rainwater tank to your house, because it allows you to always use your tank water first. It switches automatically to mains supply when your tank is empty, and stops the mains supply while there is any rainwater in your tank. The additional benefit is that the pump is out of sight, inside the tank.
We supply multistage submersible pumps with in‐built pressure controls and a valve which allows the rain to mains changeover to occur automatically. The pumps are constructed from high quality components including stainless steel casing and pump shafts, and are covered by a 2 year manufacturer’s warranty. The 20mm Acquasaver valve used for automatic rain to mains changeover is also covered with a 2 year warranty.
