Step 2 - Check your water pressure
Incoming water pressure should be tested prior to
installation. You can do this using a mains water pressure
gauge (available online or at a local plumber's merchants).
Your standing water pressure can increase dramatically
overnight by an additional 2- 4 bar when water usage is
low.
The best way to control high pressure is to install a pressure reducing valve
(PRV). These take a high pressure at the inlet, then the valve reduces it to a lower
pressure at the outlet as required. Installing one protects all the appliances and
plumbing in the property. Increases or spikes in water pressure can and do happen
which can cause filter systems and other plumbing to leak therefore we always
recommend fitting a PRV in your property if you do not already have one.
Step 3 – Sourcing the plumbing parts
Once you have located space to fit the product and tested the water pressure the
next step is to source the necessary plumbing parts that you will need.
If installing the product yourself then you will need to source the necessary
compression or other fittings required to connect the product to the existing
pipework. For high quality plumbing parts and pressure reducing valves we
recommend you shop at Screwfix. If you are having the system professionally
installed by a plumber please provide them with the product information prior to
installation.
The system comes with 3/4" and 1" BSPP Female connectors.
The MaxiSOFT is designed to be fitted on 22 mm pipework, maximum
water pressure: 12 Bar
PRV's are sized based on flow rate and application e.g.
residential, commercial. Sizing a PRV incorrectly can
cause several problems so it is always best to consult
your plumber prior to installation.
