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

I have header tank and cold water tank, both full.

Also now can't get the cap off to fit Immersion heater. Omfg

What tool are you using to try and remove it?

Sounds like air in the system, try bleeding all radiators and any manual / automatic vent points. If no air comes out I'm afraid you'll have to hire another plumber or get the first one back, I hope you haven't paid him!

I would never leave a customer like this

32mm socket and wrench as that fits the blanking cap a treat

We have paid him as it was working. Albeit was only £240 but it's the time frame.

The smaller of the 2 tanks, what was the condition of the water like, did you try pushing a screwdriver or something into the tank outlet to make sure it was clear?

 

[jpbroad1970]

The water was,is dirty. It was a bit caked up but free flowing now, rads have bled and you can tell when the pump kicks in as it increases the pressure of water coming out the rad.

 

[Aire]

What do you mean by was caked up but free flowing now?

It had some crusty bits just inside the outlet

 

[jpbroad1970]

I have given up , plumber booked ran out of ideas and patience.

 

[jpbroad1970]

Thanks everyone for your input, I'll post up results when mended.

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.
