Hi - I'm hoping you can help me with some advice as I'm fed up with being ripped off by tradespeople who take advantage of the fact that I'm female!
My hot water/central heating pump keeps turning itself on at odd hours (i.e. the middle of the night when it wakes everyone up!) & not in accordance with the thermostat settings - it seems to have a mind of its own. It also makes a loud knocking noise when this happens.
The pump itself is not a new one & I'm wondering whether it should be replaced or the problem repaired and whether a repair might end up costing a great deal more than buying and having a new pump fitted? I'm not sure how long pumps are meant to last but if this one is very old, a new one might be a better option.
I don't know if it's relevant but I have an 18month old boiler (it's not a combi) and it's working fine. Shortly after it was installed (& before it had been used) it failed to work & the tradesperson said the system was full of crap & I paid him to flush everything out & then fill it with an additive that would prevent the crap from forming again (that was how he described it).
Fingers crossed that you can advise me on what's going on, so that when I call up some new tradespeople they are aware that I've done some homework and am not going to be a soft touch...
The pump is red and has the following information on the front:
