water help no hot water

[jpbroad1970]

hi we have an issue with our heating and water system . new flow switch and new pump , system bled , all done by a professional but still no hot water or heating. when the plumber left yesterday we had boiling radiators and some hot water although the heating was switched off. my suspicion is diverter valve but unsure as to why nothing is working again now. boiler tries to kick in but says FD error (flow)

would be really happy for some advice as we have been 4 weeks without hot water no and the Mrs isn't happy.

thanks in advance
John

Ok am I doing something wrong, this is the tap the plumber drained the water out of the system with above the boiler. In my little mind I thought if I opened that valve/tap water should come out, am I wrong do I have to open anything else. I don't want to completely drain everything down just view the water or make sure it's making it to the boiler and it's not just air pushing around.

Yes that’s the drain cock and is used for draining purposes.

So I should have water come out of that?

Water will come out so long as the washer isn't stuck or the valve blocked. If the plumber recently used it then it should be fine. What I would do is attach a hose, open the valve and then go in the loft to check that the water level in the tank drops and refills. This will prove if the cold feed is blocked or not.

Nothing comes out when I undo the square bit, do I have to push or press anything, it opens very easily but not even a drip out of it when square bit fully open.

If it was me, I'd slightly unscrew the circular nut that the square nut passes through, don't take it all out but it will allow you open the drain valve further, this can sometimes free off the washer in the valve. Be warned though, if the washer is knackered you could find the valve won't re seal. Personally I'd wait till tomorrow till shops are open to get a replacement if needed.

I Agree with Craig, best wait til tomorrow 🙂

I've given up properly now.

That lock ring thing was quite loose.

My partner said she saw the the plumber draining water out there with hose attached with clear water running through, again in my head the colour of water in header tank how can it be running clear.

 

[jpbroad1970]

I think it's beyond my knowledge understanding. I can see how it all works but I'm not a plumber and I think it's best left to the professionals, just not the same one we had before.

Thanks again for all the advice.

No worries, it’s why we’re here. I hope you get sorted, can you let us know how you get on? 😉

Well another 5 hours with a different plumber and guess what, no hot water or heating. I'm at work but the Mrs has said they have replaced a load of pipework in the airing cupboard and got some sludgy water out. But it's still coming up flow error. Going to have to come back another day, dread to think on cost of this little lot. Sad times.

When you get home take a pic of the new pipe work, just to keep us updated.

Will do no problems. They were on about new radiators and all sorts Mrs is leaving piles of brown poo everywhere

Why New radiators? If they're sludged up just take them off, give them a flush with hose pipe outside and they'll be fine.

Did you ever contact @Brambles about the work? You initially told him you would give your original plumber another chance first but obviously he's been sacked off now.

 

[jpbroad1970]

I haven't yet no, we got the other plumber to fit the 3 way valve then paid him as it was ok for a couple of days then we went away . The Mrs then called the people that service our boiler yearly and to be fair they turned up as promised, even put a job off to do ours. If it's just a case of flushing the rads with a hose pipe that's something I can do easy enough, had rads off before and fitted new ones so sure I can manage that.

If it is sludge will a powerflush not help?

 

[jpbroad1970]

I think that's what it's looking like. They drained water off as per pic.no real metal bits just sludge and mucky water. Their opinion and that's all it is at the moment is as soon as the pump starts to drawer water it's drawing sludge slowing everything down to a stop.

Tall glass what they fetched off

Small glass what I've just drained out of tap off the top of the boiler pipe
