Plumbing – Replacing leaking Scalemaster scale inhibitor

boilerplumbingwater

I've just discovered that my "Scalemaster Electrolytic Speedfit Scale Inhibitor" has a pin prick leak in it.

This device is sat between a copper pipe going to the combi boiler (I have assumed)

I've ordered a replacement with the intention of replacing it myself as it looks dead simple to do. However, I know absolutely nothing about plumbing.

Are there any pitfalls I could run into when attempting to replace it? Is there going to be an "air lock" situation?

My plan is simply to:

  1. Turn off the water (which I've tested does stop the leak)
  2. Take off the scalemaster
  3. Put new scalemaster on
  4. Turn the water on.

Is there anything I should be aware of? Am I incorrectly assuming it will be this simple?

Here is the knackered one:

Your plan is decent, but I'd amend it slightly:

  1. Turn off the water
  2. Take off the scalemaster and throw it away
  3. Replace with a couple couplings and a regular piece of pipe
  4. Turn the water on.
  5. Be happy you saved your money by not buying a pointless device
