Worcester Boiler Pressure Help

[AlistairMacEvely]

Hi,

As you can see, my water pressure is pretty low on my Worcester Boiler.

The engineer left the flexible filling loop on 6 years ago. Yesterday I had no hot water and an error 227 ignoring ionisation fault. After switching the switch off the boiler overnight, it's now working again, but the pressure is low. Once I turn the tap off, the temperature seems to increase and stay there, currently it's OK 62 degrees. I saved it on 45.

In order to increase the pressure, do I switch the boiler off first before I turn one or both of the black nozzles? Which one do I turn on first?

A step by step guide will be much appreciated.

Thanks guys.

Turn both black levers to on, in any order. Turn both off once pressure is topped up ,which should be done when boiler is cold. Boiler can be electrically on or off.

Does the flexible filling loop need to be taken off after or can it stay on?

It should be removed,and the two caps ( hanging off the filling loop in your pic) fitted to blank off .
In reality,very few people can be bothered to do this !!

The engineer who installed it left them on but I did hear recently that there's some anegcy standard thing that says they must be removed. If you don't mind me asking, can you elaborate on this please? I.e. why this is a must, I'm trying to work out why the engineer left them on in the first place.

Engineer left the flexi attached because we get a million calls a day fro people who, despite being shown, are unable to top up their boilers, if we leave hose on, there's a small chance we can talk people through it over the phone.

The reason it should be disconnected is because of water regs, there's a (slim) chance dirty system water could backflow into clean mains water sytem.

Do you mean you haven't needed to top up the pressure in 6 years? Good going!
