Plumb In The Softener Inlet And Outlet Hoses; Plumb In The Drain; Plumb In The Overflow - European Water Care EWC 10 Manual

(3) PLUMB IN THE SOFTENER INLET AND OUTLET HOSES

Using the hoses provided, connect the softener inlet and outlet to the mains water pipe work,
as shown to the previous diagram.
Note: Ensure that the hoses are connected correctly as per the labels on the back of the
softener cabinet
Pressure drop across the system is rarely an issue for households fitted with cold water
storage tanks. Therefore for most households (with cold water storage tanks) and 15mm by-
pass plumbing, valves etc, the standard hoses provided with the water softener are adequate
to supply all water requirements.
For households with combination boilers i.e. connected directly to the mains water supply
without a cold water storage tank, it would be advisable to disregard the hoses and plumb the
softener directly using all 22mm pipe work valves and fittings etc, especially the non-return
valve. This would give significantly greater flow and less pressure drop across the system
therefore minimizing any low pressure effect on the combination boiler and all the mains
water system through out the house.

PLUMB IN THE DRAIN

The yellow hose provided is used for both the overflow hose and drain hose and must be
trimmed accordingly. Fit the yellow drain hose provided onto the ½ inch hose barb fitting on
the control valve of the water softener using the jubilee clip, then run the hose to a suitable
drainage point i.e. plastic stand pipe.
Please note: Care should be taken to position the hose so that:
(a) It will not kink or fold
(b) It will not freeze
(c) The length of the drain hose is kept as short as possible
(d) It cannot move and become dislodged.
Note: High water pressure may cause the hose to move during the backwash section of the
water softeners regeneration cycle. For this reason, it is advised to fix the hose in place.
Important: A suitable drain air gap should be provided to adhere to local Water Authority
Bye-Laws. The air gap should be at the point of entry from the drain hose into the drain pipe.

PLUMB IN THE OVERFLOW

It is very important that a good overflow system is provided. Connect a short length of the
yellow hose to the overflow elbow at the rear of the water softener. Run this hose into wider
waste piping of at least ¾ inch (22mm) plastic pipe leading to the outside.
