[PUM1003] Aquasaver Change Over Valve 20mm

The Aquasaver Change Over Valve 20mm is a fully automatic, hydraulically operated mains-to-rainwater changeover valve, designed for rainwater harvesting systems supplying toilets, laundry, and general household applications with automatic mains water backup.

Operating without any electrical components or power consumption, the AcquaSaver valve always prioritises rainwater over mains water when available, and automatically switches to mains supply if the rainwater tank runs low, switching back to rainwater once replenished. Suitable for up to two toilets, a washing machine, and an extra tap outlet, with dual outlets giving flexibility to use one or both as needed.

Constructed from solid brass for a fully weatherproof, long-lasting build, this valve features a built-in dual check valve for backflow prevention, and can be mounted in any position. Watermark approved and complies with AS/NZS 3500.1 when installed by a licensed plumber.
