hi guys, replaced a combi swap a few months ago and customer has contacted me, saying sometimes when they open kitchen cold tap the boiler makes a noise but doesn't fire up?
I connected hot and cold correct way if your asking lol.

The mains pressure is very high could this be causing problems when kitchen cold tap is closed after it's been turned on? Back pressure?
I installed boiler to the mi.

Have you put a PRV &/or shock arrestor inline with oncoming mains as that may be a contributory cause to issue

I went to see it today. When you open a cold tap the pressure on boiler slighter rises with a noise?.
When tap is closed the pressure goes back to normal.
It's like a surge of pressure that is doing it? What if I put a shock arrestor on the cold pipe going into the boiler?

Did you check the filter on the cold water inlet, I assume the beta com has one... most boilers do

There's already a strainer on the cold supply going to the boiler. It's only 4 months old.

The heating pressure goes up when a tap is opened?
