Ideal Boiler Filling Loop Issue

[Arrivalist]

Hi,

I have an Ideal combi boiler (Vogue 40) and I noticed low pressure today. Went to use the filling loop and water will not enter the boiler. Water side is fine and when I take off loop and open the boiler side, water comes out. So assume inlet valve stuck?

Any idea on a quick fix or do I need a trusty plumber?

Cheers!

You sure there isn't an isolator on either ends of the filling loop?

The loop tube is just an open tube, if that’s what you mean.

Something like this?

Indeed. The water starts to flow when opening the blue side BUT it will not enter the boiler. It’s as though there’s a blockage beyond the black tap.

Have used it many times before so assume a failure of something.

Are you sure the valve moved when you turned the handle? Those crappy valves can get stuck and the handle then twists without operating it.

Alternatively is there a non return inline that might be stuck?

If it's just a ball valve and nothing else you might be able to stick a screwdriver up it to poke any blockage. Obviously being ready to shut the valve before getting too wet.

I undid the filling loop from the cold water and turned it on and water goes into my bucket. If I take the filling loop off of the boiler side and open that valve, then water comes out of the boiler. So basically there doesn’t seem to be a problem with the loop itself. I think it’s the non-return of valve on the boiler side that is knackered.

I could fart around with a screwdriver BUT I seem to have just enough pressure for the boiler to work at present so not keen on losing any more water from the boiler which is registering pretty much zero at the moment.

I think the non-return valve will need replacing anyway so have a plumber coming on Monday.

Thanks both of you for trying to help.
