water pump issue?

[ShaunCorbs]

Yes as the hot water circuit eg upto the cylinder is the shortest circuit normally any bleeder / venting points around the cylinder?

hi shaun, just to remind you i don't have a cylinder. you want me to still try?

 

[ShaunCorbs]

How do you have hot water then ?

 

[finest1]

we get domestic water via a " Main Multipoint BF ERP Gas(Natural)Water Heater" in the bathroom which supplies our hot water for bathroom and kitchen

 

[ShaunCorbs]

That’s fair enough so shut all the radiators but the closest one to the pump and then run the system

OK i'll give this a go tomorrow, and i will update you. thanks for your time

thanks

Did you keep bleeding any air off the rad !

dear all, thanks for your advice. i'd like to give you an update:

i called in a CH engineer to help resolve the issue. to cut a long story very short, he did think there maybe 2 issues, airlock, or water pump. he decided to go down the water pump route and said lets see what happens. he changed the water pump and then bled the boiler. so i have no issues there. during the install he had to apply force to remove the pump, that's fine we knew that from the conversation above. so all was fine, everyone happy. however during the install he decided not to change the valves to the new ones. i asked why. he said 1) we would have to drain the system and could cause an airlock 2) the valves are fine, no need changing them if we don't have to. i was surprised by this, and told him so, but took his advice. all good. i went to check the install hours later, and saw the water pump and valves wet. it was almost like it was sweating, but we had to put a container under to catch the drip. i text him and sent a video. he said he will come next day and he did. however, this is the heart of the matter. he tried to tighten it and the weep was still there. he then says to me, "your valves are defective". i reminded him that he confirmed the valves were fine and they didn't need changing, so you cannot tell me that i have defective valves. they weren't defective for over 30 years. he then said there is nothing he can do, he will have to charge me to change them. his job was to change the water pump only, valves wasn't part of the job. i then replied and explained to him that when i booked a job with the office, i said my CH doesn't work, i think its the water pump. during the conversation i told them i have the pump and valves on site. I told him all this when he came to the house, and gave him the pump and valve to hand. he declared its a separate job, nothing he can do and left.

at this point, i think its worth me saying that when i booked the job, i asked the office if the engineer can call me before hand as i will be happy to drain the tank, if that helps save time. the office said that they will get him to ring. he didn't, i didn't hear anything, he phoned me to say he's outside my house. he was two hours early, which i wasn't complaining about.

i lodged an investigation with the firm which, as you can imagine, is slow. promises of "I'll call you back" but never do. the latest conversation is that they are willing to replace the valves but its chargeable.

so i am hoping to get some perspective on this. i feel that the company should replace the valves with no cost as the engineer had caused some damage to it, they don't think so. they're stance is that they were only there to change the water pump.

what do you think?

thanks

The valves are fine did he clean the face up and put new rubber washers on

If he damaged the nuts you can replace these by just using the slots on the underside of them and removing them

Would call them back and say it’s leaking and you want there insurance number as it’s going to cause damage
