Sumo II
Non-Electric Water Softener
Highly efficient and compact non-electric water softener.
Reliable, simpler to operate and less expensive to maintain, than traditional softeners.
WHY CHOOSE THE
Davey Sumo II Water Softener?
Hydraulically driven smart valve softening engine
The Sumo II has a non-electric hydraulically driven smart valve softening engine, which has been designed to promote high flow rates as well as provide precise control throughout all of the softener operating cycles. Unlike traditional softeners, the Sumo II is non electric and is hydraulically driven by demand from the home. With the
Sumo II there are no electrical running costs; it will continue to operate during a power outage but more importantly, unlike traditional electric driven softeners, will only operate when you need it.
Highly efficient softening media
The Sumo II comes loaded with high-efficiency compact softening resin; this means the Sumo II offers more softening capacity than the standard resin used in traditional softeners. This makes the Sumo II more efficient in its operation than traditional softeners - so much so that the Sumo II will use up to 75% less salt than traditional softeners.
Accurate metering
The Sumo II accudial metre allows fine-tuning to precisely reflect the household’s water hardness and usage which allows the system to use the entire media capacity between regenerations. This means the Sumo II can rapidly regenerate in as little as 6 minutes compared to more than an hour for traditional softeners.
Compact design
The Sumo II has a compact footprint which means it can be installed in cupboards and places where a traditional softener can’t.
Ready for installation
The Sumo II is supplied ready for install including integrated by-pass valve and fittings.
