there you go, a "plumber" who didn't know what he was doing & fitted totally the wrong boiler for your house, if the builder told him to do it then he is equally responsible & i would be asking for the boiler to be replaced with a conventional system at his cost.

my builder didn't tell him too!!

My builder told him to change the stop tap and the pipe connecting to that, to see if it would provide enough pressure/flow etc to fit a combi. The plumber was supposed to test this & then only put in a combi if it was suitable.

I will not be out of pocket on this, my builder is dealing with the plumber and sorting out the payment/lack of payment etc.

Luckily my builder is excellent (and also feels embarrased about recommending the plumber who is being awful) and will make sure it is sorted for me.

oh and the pump didn't work. the mains supply is too weak.

when the pump was on the bath taps ran for say 20 seconds then all water stopped for around 20 secs. it did that continous.

i told the plumber who said that's because its sucking out all of the water from the mains (therefore it would take all my neighbours water too) and to contact the water board.

the water board had been out previously and say they are meeting the minimum requirements, albeit only just.

Think you've just answered your own problem there!!...

Hi.

OP you should have listened to your own advice and fitted the new roof tank cylinder option.
You clearly didn't have the pressure or flow to support the combi. (as posted by yourself previously)

Your options now are to:
Get the above pump.
Have a new main supply fitted.
Use a gravity system.(tank in roof).

Really, really poor advice from the 'plumber'

Given the extremely poor pressure/flow I'm not sure the pump will work in your case as it's a shared supply.

Yes I was going to get a conventional.

It was when the floor was dug up and we saw that it was old metal pipe onto the newish blue main supply pipe that there was the possibility of getting a combi.

I said, yes if that is changed and the flow/pressure increases enough then a combi would be good. But only if the flow etc increased enough.

The plumber screwed up and I will be getting a conventional fitted now.

Yeah. I just thought a registered installer/plumber would only have fitted the bloody combi after testing once the new stop tap & pipe was fitted.

we agreed conventional. it was only when the floor was dug up and my builder saw the the blue plastic supply pipe was laid but connected to the old pipe and old stop !!!!, that he said to the plumber change the pipe and stop tap and if its then good enough fit a combi.

So the builder has to take some (albeit small) responsibility for this situation. Sorry to say this but its getting more complicated by the minute and it looks as though it might be going to cost you some money.

A conventional system was clearly the right way to go in the first place.

Is any of this written down in the way of a contract?

if the water board say the pressure is the min they will be allowed to provide then that isn't suitable for a combi boiler installation, yes the boiler will work (maybe) but what you now have is the whole house hot & cold running off of whatever water you have coming into the house so no i would have never fitted a combi, if the pressure in the road is at min then changing your pipe wouldn't make any difference to the pressure you have & at those low pressures a bigger pipe wouldn't help much either.

there are only two ways to sort it, the water board up's the pressure in the rd (unlikely) or the boiler is changed, have you checked the plumber was gas safe reg ?

i hope your builder is as you say but looking at the way the drylining was done & the way the ceiling was plasterboarded i doubt it very much.

Hi.

666.

You might want to view the Salamander video on the website.

Pay particular attention to the orientation of the pump.

As said I would still be wary of using it on a shared supply such as yours.

GSR.

What about a CWST tank in the roof fed from the mains with output via pump to DHW inlet to the combi and thence to hot taps? That gets around not directly pumping mains, dispenses with the problem of the shared supply and doesn't mean changing the combi for another boiler. Not convinced about that Salamander device tbh.

Cheers

Edit: OK now I've read it and seen the vid I might be being a bit harsh about it.
