Hello so unscrewed the top and wasn't really any hissing at all water started leaking pretty much straight away as you stated tightened back up and still making the same noise you did mentioned to try while CH is off which I did the hot water is set to come on twice a day heating is controlled by thermostat downstairs.

the noise I can hear I hear all the time regardless if heating is on or hot water is being heated so would this definitely point to it being shot?.

I'll try dig out my tape measure my father in law is good with this sort of thing so if it's a straight swap out he could do it.

Does the noise stop completely when both the central heating and the hot water are off?

TBH most central heating pumps make some noise, unless the noise is disturbing you then there may be no need to change the pump in a hurry.  If you can get your F-in-L to come out to replace the pump if it fails completely on Christmas Eve then again you don't really need to rush to replace it.

Sometimes you can get more noise if the impeller (the bit inside the pump which pushes the water round) gets some muck on it.  If he knows what he's doing your F-in-L could try taking the pump apart and see if it needs cleaning.  Although unless the valves either side of the pump still work he'll probably need to drain the system down - and if he does that then just replacing the pump may be worthwhile.

Yeah definitely the pump because when I go to change the speed settings if I like turn it between say setting 1 and 2 and keep it there ticking stops soon as I put it on a setting starts ticking again.

i can't complain 23 years isn't bad it's outlasted the last 5 cars I've had lol appreciate your help I'll give the father in law a ring tomorrow
