UNVENTED OR DIRECT SYSTEMS
Connection to the water softener should be made with 22mm or 28mm copper pipe and
not with flexible hoses supplied,to ensure that a satisfactory flow rate is maintained.
You will also require a suitably sized bypass set and check valve. Full flow valves are
recommended. Large bore flexible hoses are available from EcoWater.
DRAIN HOSE
We recommend that the maximum length of drain line is 3 feet before entering an air
gap. Also any rise in height of the drain should not be above 3 feet.
CENTRAL HEATING SYSTEMS
Central heating systems should always be treated with a proprietary corrosion inhibitor
regardless of being filled with softened or hard water. Systems containing aluminium
should always be filled with hard water unless instructed otherwise by the manufacturer.
