Radiators not heating up after new pump installed

[Sjcoff]

What is the PC number? (on the right.)

You say it is lying on the ground; but is it sticking up in the air with the data label at the top? A more general pic, so we can get our bearings, would help.

Hi have attached a clearer picture and the PC number is 1817, it is flat on the ground with label at top as shown.

The piping comes from boiler on the left into it and then goes off to the right and to the radiator in sitting room .

Once the heating comes on the pipes in the bedroom next to hot water cylinder make quite a racket and you can hear water like gurgling in them .

I can't see any feed/expansion pipes coming off the primary circuit to the cylinder. Is your "expansion tank" a cold water storage cistern with one vent over it from the top of the cylinder ? Meaning you have a primatic cylinder.

Hi yes that is exactly how the black plastic tank is, have attached image.

Which pic's would yous want?

Would draining the system down again and refilling it again do any good? As the radiators where working fine before pump went.

1817 means it was made in 2018 week 17. It looks as if it's lying on a floor board, with the body sticking up. If so this is all wrong as the shaft is vertical: it must be horizontal. Was the previous pump installed the same way, and had it failed? It needs to be rotated so the connection box is on the top; this may mean cutting away some of the floorboard.

@Sjcoff, that all needs sorted out, as I mentioned before. The system needs setup properly again and it really needs someone that has one pipe experience as they are difficult to setup properly. It take time, perseverance and it is a farf to get it right. All rads off, find the sequence, fill each one in turn and then balance. That's at least a days work and it then usually needs a 2nd/3rd visit to bleed and fine tune.

There was no need to drain down in the first place though, the rads should have been locked off and the f&e cistern bunged so draining the system could have been avoided and you wouldn't be in the situation you are just now.

#madrab it was an engineer from SSE that done the replacement pump and drained system. I will be calling them back out as have a service plan with them, but though I could of just done it with bleeding radiators .
Also when you mention all rads off fill one by one, do mean turn off at both ends then open and bleed one then close that one off then move onto next one?

 

[Madrab]

Unfortunately the engineer probably had no experience with a one pipe system. In a normal 2 pipe system bleeding would usually take care of it but then they should have done all that and left the system nice and hot before they left & not left it to you to sort out. You need to specify you have a one pipe system and it needs setting up properly, when you call them. You also need to point out that you have been in touch with the pump manufacturers and they have stated that the pump should not be installed the way it has been and that need corrected as well.

You wish to be assured that the system will be left fully working and all rads are fully hot before the engineer goes anywhere.

Thanks Madrab, will get onto them 1st thing Monday and explain all that so hopefully they can send someone with bit knowledge of the 1 pipe system, as the young lad that came had to ring someone a few times .

One pipe or not, he should still have been able to mount the pump in the correct orientation, use the correct cable, fit the gland properly and make sure it was all working satisfactorily before he left.

it was an engineer from SSE that done the replacement pump and drained system.

Then SSE should be taken to task about it. I thought some guy from down the pub had done it as a favour for a pint.

SSE are extremely poor for any work in any way, definately wouldnt use them for anything

 

[Madrab]

One pipe or not, he should still have been able to mount the pump in the correct orientation, use the correct cable, fit the gland properly and make sure it was all working satisfactorily before he left.

That reference was specifically to do with setting up a one pipe system and nothing to do with the pump (mis) install that was covered in the previous comments.

 

[Sjcoff]

Update on this problem, had SSE out today and this what he said to son as Ibeasntv in.

Pipework leaking from LHS pump valve, cut and replaced.

Head pressure from boiler side of cut pipe but only trickle from pump side.

Unable to remove airlock advised customer unable to do anything else and after speaking to manager advised that system and pipework need replacing.

All was working fine till pump failed and they drained system to replace pump.

 

[ianmcd]

you will never learn , you got SSE in ??? its a wonder they just didnt give you a quote for a power flush, stop wasting money and get a decent independent experienced installer , ask friends or neighbors for recommendations, post where in the country you are and someone on here might be able to recommend someone near you

 

[Sjcoff]

Only had SSE out as have full boiler cover with them and obviously its not worth it. In Newcastle, getting mates friend round to see what he says, he says it is probably a blockage caused from the tank being drsined
