Key to increase pressure

[Android 07]

My ye old Vailant combi boiler sometimes loses pressure. I then have to increase it before there is combustion and I get hot water / heating.

A muppet plumber I called last year or so broke the turning key that let me do this. I watched some Youtube videos and could not turn the switch with any of my flat head screwdrivers. I called a boiler and he charged me £50 for a minute's work. The guy had one of those multi-head screwdrivers.

Can I buy a key that I can insert and turn the pressure switch in the future?

This is what my boiler looks like ( I put the green arrow ) :

There will come a time when that's so deformed that you won't be able to use it. Fit an external filling loop.

Would I be able to do it myself?

Not difficult to do If you have basic plumbing skills and a few tools. Can you solder copper pipe and fittings ?

Erm..... no. I think that answers that question then lol

You could use compression fittings if it's just the soldering that you can't do.

is that square 5mm ? a radiator bleed Key - Square may fit , so you are turning the whole square and not using a screwdriver which will disform

Sorry for the loooooooong delay in getting back to you.
It looks like a diameter of 1cm.

As Terry advised, by far your best option here is to have an external filling loop fitted

Roughly, how much would that cost, muggles?

 

[muggles]

Probably no more than £100

If fitting an external loop get a decent one not the cheap crap that are available
