Has my hot water cylinder coil broke?

[Dave18183]

Left it again for most of the day and perhaps it back to a littler dirtier

 

[Dave18183]

I just feel like I could be slowly replacing the dirty central heating system with clear water from tank refills, and this isnt the behaviour of the coil being intact and slowly flushing the hot water tank clear.

Nope that’s water board dirty water

 

[Dave18183]

Ok. Thought I feel like I’ve smelt chemicals when it was at its strongest. Dirty boardwater have a smell?

Can I ask how you can tell the difference between dirty board water and radiator water?

And why would the tank keep filling and then running clear. the cold supply from the water board is running clear now, and has been for three days, so if this is dirty board water in the system how many tank full do I need to clear it. 13 bath fulls i.e 13 full tank empties and refills And still going

Yes as they’ve probably cleaned the pipes

radiator water will be black

your cylinder is full would get the plumber back to drain it and refill

When you say cylinder is full you mean full of crap? By drain it and refill do you mean more a back wash to clear it out.

I feel I have already been draining and refilling it about 13 times. Same hot water tank (150 litre I think mine is) fills the bath with hot water (all those dirty bath picture are hot water) and is running cold by the end (so I feel the tank is emptied each time, apprecaite it is refilling as it empties mind

Yes you won’t fully empty the cylinder

also did you have a letter off the water board stating there going to be doing work etc ?

you can phone them up and request a visit from one of there engineers as you’ve got discoloured water since they’ve done the works

No letter. As I think I said in my first post, there was a leak a few streets down the hill which affected our supply (it was leaking up through their pavement). And when it can back on there was a lot of noises from the tank/airing cupboard (air and water sounds not clunking sounds)

Change the cylinder if you want to, but if the coil had gone your heating would be at the same pressure as your cold main so the gauge would be over 3 bar all the time and your boiler PRV would be passing water all the time.

Ok, thanks. Boiler gauge hugs 2bar at times but not seen go higher last
Few days

is a tank flushing the only way im
Going to clear the water? I guess if the coil hasnt gone there is no real worry, it’s just a Little dirty and will eventually clear/settle down?

As mentioned in the original post
I do have a drip from (I assume) a PRV flowing through the tundishh and out to a drip outside external to the downstairs toilet. I had read that was a symptom of a broken coil. Any idea what the cause of that might be? Thanks.
