Thanks for the advice. Am I within my rights to ask for him to fix this FOC?

Hi, I had a gassafe plumber come and change my heating pump recently and after he'd finished it I noticed an electrical crackling sound which at first I thought was coming from the pump. The sound got worse and worse with some loud pops happening. After a while the plumber realised it was the...

The boiler requires a pump overrun connection but it is not wired up yet because the more I learn, the more I notice other stuff that needs changing like that valve. I'm not sure if it would be better just to connect the overrun wiring and open up that gate valve a little or leave it as it is...

Makes perfect sense, thanks for the explanation. I can't decide if what the Honeywell does is good or bad but it was certainly bad for my diagnostic efforts in this case.

Don't think so (well maybe pump motor). The system 3A fuse if blowing soon after there is any demand and I'm not getting enough time to see what's happening in the cabinet with the pump and the valves so I was hoping to manually operate one of the valves to see what happens with the pump. I...

Its on the only pipe out from the pump which doesn't run through a 2-port valve and runs back up through the roof (I assume to he boiler return flow) and branches into the water cylinder primary return.

Ok, that explains it thanks m8. I thought it was a physical relay so thought it would connect the pump and boiler circuit. But its a Honeywell.

Hi, Should opening a zone valve manually normally start the boiler and pump or just open the valve so water can pass?

Hi Agile, yes that's what we are talking about. Thanks for the further confirmation :)

I assumed that was a typo - pretty sure he just wrote pump twice by accident.

] Thanks Bernard, that was just what I was looking for - some confirmation that I am thinking in the right direction. Maybe I just need to separate out the pump from the other feeds and connect only to the dedicated boiler feeds. I'll study the thing a bit more first. While I was fixing it...

Hi, yes I have the installation manual which shows the boiler side of the wiring which is simple. I'm just wondering if on an s-plan system normally the only wires going to the pump would be from the boiler side L,N,E or if it's normal to have L, N,E from other places sharing the same connection...

Hi, This is a follow on from my thread earlier this year: http://www.diynot.com/diy/threads/am-i-being-harsh-on-this-plumber.428970/ This is where a plumber installed this boiler but said there was no wiring for a permanent live connection or pump overrun. He only connected 3 wires/cores to...

But not careful engineers deserve to be fried? :shock:

I just have too much stuff to do. I bought a house that was a repossession and am spending most weekends and evenings doing DIY already. The only sure fire way to lay the cable I know involves taking up flooring and floorboards and it would take me ages and can't have unboarded floors for a...

Yes, I totally regret it. The fan failed (according to the same plumber who did the new install so it probably wasn't that) and I was quoted £250 to replace the fan. So I took the opportunity to fit a new condensing boiler obviously having bought into all the government A rated, efficiency...

Does that sort out the permanent live problem, frost protection etc?

Sounds like it doesn't it? I've already told him that if it can be done for a low price like he suggests I won't be going down the court route. I'm not convinced I've seen any evidence in this thread that a low price option exists which would satisfy the warranty in any case. I think the...

He is proposing to leave a hole. He actually left the old boiler out in the rain in the middle of the front lawn and Gypsys got it about a day later.

The boiler is on the ground floor at the back of an integrated garage at the left side of the house. It looks like existing pipework runs from the boiler across the width of the garage ceiling (2.5 meters) across the top of a stud wall above the living room which is behind the garage (not sure...
