Siting the softener
This should be as close to the rising main as possible. Allow hard water take off points for a drinking
water facility and /or an outside tap
if required.
With modern softeners this is not essential, due to the
quality of the resin.
For easy DIY installation we recommend the fitting of a hard or filter water kit. If the stopcock is located in
a difficult position to create a hard water supply, you can fit a Reverse Osmosis system.
The distance between the waste and the softener should be as short as possible.
Ensure that both the waste and overflow are not subject to excessive temperatures
(freezing or over 120°
F).
If you are siting the softener in a cupboard, ensure that the base of the cupboard is adequately
supported.
If the softener is being installed in a loft, it is recommended that you place the softener within a well
insulated 25-gallon tank. The overflow on the tank should be below the softener overflow and be a
minimum of ¾” in size.
Non Return Valve
In single dwellings, a single check valve should be fitted. This is supplied with our 15mm installation kits and
can be ordered separately.
Check list
If you purchased an EMWC fitting kit with your softener, all valves required for installation will be included.
Combi boilers require a
Combi Kit.
Pressurised systems require a
22mm Fitting Kit.
Check you have ordered
the correct fitting kit for your installation, before you start.
Water Pressure Test
It is important that you carry out a pressure test. High and low water pressure can result in damage to/failure of
the softener. Although the softener is tested to a pressure of 8 bar we recommend the fitting of a pressure
limiter should your pressure exceed 5 bar (70 psi). We also recommend that any household appliance using
Planning your installation– the plumbing part.
Always observe the water bylaws. Make sure there is only one rising main and that you are allowing space for access to
the unit, for filling with salt and possible maintenance in the future.
