Removing and bypassing rainwater tank pump systems due to customers running out of water unexpectedly? 

AcquaSaver is a mechanical auto changeover valve meaning it won't stop working unexpectedly. With no possibility of solenoid valve or electrical failure, pump systems using the Water Widget offer better reliability than an electronic changeover system. 

AcquaSaver can be used in conjunction with the complete range of Wilo domestic surface and submersible water supply pump systems 



The AcquaSaver® Valve is a fully automatic mechanical rainwater/mains water changeover device designed for pressure pump supply systems for harvesting rainwater for the toilet, laundry and household applications with automatic mains backup.
