When I unscrewed it earlier I stuck some wire through it. So I don’t think it’s blocked, sadly that would’ve been to easy haha

Ah sorry my fault, I didn’t explain very well. So earlier I unscrewed the hose but from the other end, then I turned the water on and it came out. This time I was going to unscrew the hose but this time from the check valve itself giving me access to the inside of the valve if that makes sense...

Thank you very much, I appreciate all help this afternoon. I wasn’t going to remove the check valve itself, I was thinking of unscrewing the silver hose from the valve itself and maybe seeing if I could ‘clean it out or reset the spring’. Was worried if I took the hose off, water might spray...

Oh dear, that doesn’t sound good. Do you think it will be difficult to replace? I was going to get another 15mm one. Also, if I unscrew the filling loop, will water come out or do I need to shut of my mains supply first.

Apologies these were the best I could get. Hope they help, the hose has a width of 12.5 mm, so yeah about 1/2 inch.

@terryplumb Haha indeed. Last question I promise, any idea what size it might be, bearing in mind the boiler is probably 15-20 years old, I’m thinking probably 15 mm. @CBW Thanks, I’ll check that out, I’ve never checked before.

This should be fun to access, there is literally no space on either side One thing after the other.

Thank you Terryplumb, this is probably a really stupid question. But which one precisely is the check valve, I will try and buy a replacement before I call out an engineer. Just want to make sure I get the exact right part. Thank you.

I have attached the underside of The boiler and the other end of the filling loop. I hope they are clear enough.

So, done that, and after barely opening the valve water started literally gushing out. Turned the valve back off and reconnect the filling loop. Guess it’s the non return valve as you suggested. Can this be unjammed or does it need replacing? Thanks for your help this afternoon.

Hi Jurassic Sparkk, thank you. Just to be clear (so, knowing me I don’t do anything stupid) should I unscrew one or both ends of the silver hose and then slowly turn the valve through 90 degrees? And see if water begins to flow or have I misunderstood? Thank you, sorry for the silly questions.

Thanks CBW, I typically would repressurise 2 maybe 3 times a year, keeping it around 1.5 Bar. So they weren’t frequently used. Would this be something I could fix or at least look at? I was thinking of unscrewing the braided silver hose and trying to clean that out, see if it was full of...

Hi Everyone, was just hoping for some advice regarding pressurising a boiler. I have a Vaillant Turbomax, not 100% sure exactly what model but it’s about 20 years old now. My boiler pressure has reached 0.5 Bar so I thought I should open the internal filling loop and repressurise. However when...
