How should all the boiler taps look when in correct, normal position

[Wantstoknow]

Good evening,

Last time I contacted my landlord re; boiler noise & pressure she sent a plumber out who was lovely & said that one of the little black taps had been left in the wrong position when I topped up the pressure. Landlord was very angry & said next time I would be charged for the call out if the plumber wasn't "required"

Here's my question, if anyone could help. Why is my pressure rising up to 2.5+ every time I fire up the heating or turn on the hot water? I've got a main combi eco elite boiler & was wondering if anyone could tell me how each of the little black taps should be facing, for normal, day to day use?

Many thanks in advance and happy 2023 when it comes

Post a pic of the wee black taps and the valves, the normal position to be off would be 90deg to the valve it's sitting on

@Madrab Thank you so much for replying to me. I've a pal who's a plumber on TIKTOK but his messages are stopped cos he's been swearing.

Obviously I don't want to me messing with the boiler if it needs a plumber but don't want to be charged for a wee tap in the wrong position

I will reply as a non-heating engineer, and let the experts come in with corrections and technical stuff later.

Presuming your system is in good order, the pressure will rise when the boiler fires. Because water expands when heated.

This is normal.

Sorry, I should have stated that it's rising higher than 2.5 & I've bled all radiators

Re: the taps / valves.

This might be "the filling loop".
Via this, (mains) water can be added to the heating system (which is otherwise a closed loop i. e. sealed).
Usually when the system is being refilled after works on it.

The pressure will also rise if mains water is being added to the system via the filling loop too.

 

[Brigadier]

If the valve / tap on the filling loop is letting (mains) water through, and there are no leaks in the system, the pressure will continue to rise.

I'm past my knowledge now, so post pics as madrab suggests, and I'll sit back and be educated too

It's all over my head. I've a feeling that one or more of the taps are facing the wrong way & if someone can tell me how to correct them, ie point that one the other way, I think I can just about manage that. All the 90 degrees is over my maths level

 

[Madrab]

The black handle in the red box to the right should be at right angles (90Deg) to the valve it is part of, at the moment that valve (CH system end of the filling loop) is open

the black valve in pic above is 90 deg/right angle to the valve its on and that shows the valve is shut off

I need to check what the position of the valve in the left hand box (cold mains end of the filing loop) needs to be to shut that valve, though I suspect it should be vertical.

You will then need to open a rad valve and bleed the system pressure out until the pressure on the boiler drops to 1 bar.

@Madrab is correct, but if you dont want to bleed a rad to lower the pressure once the filling loop valve is closed, at the top RH of your pic there is a cut out with a small white handled tap , this is the boiler drain tap and will be a lot easier and quicker than a rad air bleed point

If there is air in the system, this compresses quite easily. Pressure rises are therefore less pronounced.
By bleeding the radiators, water has now replaced the air. Water is not compressibleressure rises when the water is heated are much more pronounced.

Don't be downhearted. Just looking at those taps gave me an attack of the vapours!
That's why good heating engineers are so valued

Rubbish the pressure is rising because the filling loop has been left turned on

Done as told with right hand one and the pressure isn't rising up now when I turn the hot water on

The one on the left is currently facing the one directly in front of it
(Tech is another foe of mine and I can't seem to delete the extra quoted post from you @Madrab )
