DIY Scale Centurion Whole House Fitting

Installing a Whole House Filter DIY

One of our clients who bought a Standard Size Whole of House Water Filter with Scale Reduction sent us this message recently

Following receiving the filter we got a quote from a plumber and I also looked into self-installing.

I decided to self-fit using plastic piping and fittings. It was only a 2 hour job.

Here is a simple pipework diagram + example of parts required for DIY installation.

This was a very straightforward job once I’d worked out what was required.

Thanks!

Here's what you'll need - please ref the picture below. The same principle applies to any of the whole house filters and anti-scalers

All code items are John Guest parts. You can simply Google them to find a local supplier

A) Assuming your in/out pipework is 22mm get John Guest PEM062215WP / Straight reducers 22mm x 15mm / Quantity 2

Or if you have 15mm pipework get 2 x PEM0415WP / Straight Coupler 15x15mm (See Note 1)

B) JG 15BPEX-41640 PE-X / Pipe 15mm / Quantity 3 meters

C) JG 15ESOTP Shut off tap / Quantity 3

D) PEM0215WP / Equal T White 15x15x15mm / Quantity 2

E) Connecting to water filter (22mm pipe) - on both sides - is PEM0322WP / 22mm stem elbow / Quantity 2

These go into PEM062215WP / straight reducer 22 x 15 / Quantity 2

Note 1 Becuase the filter has 22mm male piping, if your pipework is also 22mm you can simply make everything 22mm. Simply Google for John Guest equivalents to the 15mm sizes above.
