Low pressure but where’s filling loop??

[Siobhan]

Hi all and thanks so much in advance for any advice! My boiler’s pressure is below 0.5 but I can’t see where the filling loop might be. In the photo below I though perhaps I should attach one to what look like valves on the two identical pipes on the left, but these both carry hot water so I guess that’s not it. Excuse the beginner’s ignorance but I’m trying to get a grip on the basics here to maybe avoid having to pay for a plumber (if I can even get one) at this time of year! Also including photos of the hotvwater tank. Last 2 photos show the pipes leading into a pump for showers, don’t think this has anything to do with boiler pressure but including them just in case. Any advice would be much appreciated!

Tell us what type and model of boiler and the set up. Then we will guide you to where and how to give your system a squirt. centralheatking

Thanks for replying, it’s a Vokera Minute 35HE Gas boiler- does that help?

It’s a system boiler by the way with hot water storage tank upstairs in the hot press

I like all the compression fittings next to and above electrical components.

I can't see a filling loop in any of those pictures I'm afraid. You are looking for something that most likely looks like this - https://www.wolseley.co.uk/wcsstore...roof-pdp-w/std.lang.all/12/91/171291_wpdp.jpg

I just checked your boiler it does not have an internal filling set up. So hopefully somewhere you will find
two x shut off valves a bit like washing machine isolators , even with a shiny silver flexy connector.
Now normally they are close together and under your boiler, but you might find them in a utility cupboard...sometimes and often the loop is missing or lost ...so look around for what Stigster has put up...and report back...we will get you there ...centralheatking

That’s what I thought, do you think that means I’ll have to get the plumber in?

Could it possibly be fed from a (the) tank in the attic with a NR valve, this would give the minimum required pressure of 0.5 bar if the boiler is on the ground floor, it should have its own dedicated tank for this but I think shortcuts (wrongly) are sometimes employed where it is taken from the cold water storage tank, if so then the NRV may be sticking.
It is often teed into the cylinder coil.

It's a system boiler and unvented cylinder Jong.G. shouldn't be any thanks in loft.
