Leak from pump valve

[PhilT2000]

Hi,

I'm a complete novice to plumbing, but have a problem i feel could be easily solved - just after some advice.

I'm getting a slow drip from a component below a pump attached to my boiler, that I've identified as a pump valve (ball).

The water is seeping from what looks like an adjustment screw, at the top of the component in the picture attached. I've tried turning this a small amount in both directions - both result in more water!

What I need to know is whether I'm likely to be able to stop the leak using the valve, (eg which way to turn it) or whether I just need to get a plumber in (after the bank holiday weekend!)

Thanks in advance

Phil

needs a new one as its unrepairable.

it shouldnt gush out though so you have time to organise someone.

This a very common fault with these pump valves. I would recommend replacing them both with the gate valve type pump valves.

If you are comfortable with draining and re-filling your system, adding new inhibitor with consequent bleeding of radiators etc. this is a job you could do yourself for about £20/£25

Thanks for the advice, much appreciated.

Can you try a dose of Fernox Internal Leak sealant in the system?

Ideally, gate type valves should be used.

No idea why those awful ballofix valves are still sold (and used).

Never ever had to change a pump and had the valves 'hold', or not leak when opened after closing.
