Thanks for that. I believe you are right because this has happened previously. I can find a brass
object with a red plastic cap on. Is this what I am looking for? I can't find anything that looks like the images on the internet ie a red circular casing!
If this is what I need how do you get the cap off?
Thanks for your response. Found it recharged it as instructed. Hot water still ok. Central heating on pressure climbs rapidly to vent still?
Thanks for your help any further suggestions welcome.
Thank you. A plumber has just been and confirmed your diagnosis. The pump is knackered. A pump is for sale on e bay for 57.00.
He says its not worth it and is quoting for a new boiler. Is it such a big job to replace a pump? How much should it cost for labour? You will already have a positive feedback thanks again for your help.
