Description
The Walrus HQ400B is the current version of the Walrus HQ400, for homes with two to three bathrooms and up to 3 taps running at once. It performs exactly like the original HQ400, with silver ions added to the casing. Pump, motor, pressure tank and electronic controller come in one compact, quiet unit that starts when a tap opens and stops when you're done. Anti-cycling prevents constant restarts from a dripping tap or minor leak, and the pump protects itself with a dry-run shut-off that resets automatically, plus motor overload protection. With a foot valve it lifts water up to 7.6 m, so it can sit above the tank. Stainless steel impellers and corrosion-resistant materials throughout give a long service life, and indicator lights show working condition and diagnostics. Feed from a break tank. Never connect directly to the mains.
