Help! I’ve over pressurised my boiler

[Mrsfrumble]

Yes, I’m an idiot, I know…

In my defence it’s in a rental flat and I’ve never repressurised it before. I did it this morning to 1.5 bars, but obviously didn’t close the valve tightly enough, and next time I looked at the gauge to check the pressure was holding it had crept up to 3 bars. Valve is now tightly shut, and I’m bleeding radiators to see if it will help. Has anyone done this before? Do I need to bleed every radiator in the flat? How long will it take to get the pressure down? Please help me 😬😬😬

I’m off to get my second vaccine this afternoon so could have done without this.

Okay, so the valve was not closed!!

It is now closed a quarter turn, at a right angle to the pipe. I bled the radiator again and the pressure is down to 1.5 bars and holding.

Thank you, @PigletJohn and everyone else, for teaching me what a quarter turn valve is and another valuable lesson in adulting. Tomorrow I will find out where the stopcock is too.

Moving every couple of years and having a letting agency handyman coming round to sort stuff out has clearly deprived me of some valuable skills, but I can now add repressurising a boiler and bleeding a radiator to fixing a dishwasher, washing machine and coffee machine, all of which I had to do for myself during lockdown. Maybe there’s hope for me after all…

And thank you @Hannahcolobus for coming back! Pretty sure it’s sorted now.

All's well that ends well!

Stop cock is normally under the sink and should be turned off and on regularly so it doesn't sieze up and not work in an emergency. (And there endeth my plumbing lessons).

Well done for filling it and fixing it.

I remember reading an article once about how never having the chance to learn DIY skills was a genuine problem for “generation rent”. Apparently I’m living proof!

Thank goodness for Mumsnet hey!

Hooray :)

it all makes sense when you know

incidentally, yellow is usual for a gas valve, and blue for a cold-water valve (the same colours as are used to identify plastic pipes buried in the ground). I expect your fitter just had a yellow one handy, so you can't trust the colours for certain.

the silver one is a very cheap type, and can leak at whim.

even better pic

I did exactly the same! Glad it’s sorted
