Cold water tank in the attic overflowing

[GGg]

Split coil in cylinder or faulty mixer

Mixers are brand new, how would I test a split coil? Wouldn’t the heating tank be draining?

Is your smaller f&e tank above or below the larger cold water tank

Below I think? The plumber bloke tested the “levels” in the tanks and they were fine?

 

[Riley]

If the level of the f&e is above the cwsc then if the coil is split the two will try and level out.

If the level of the f&e is above the cwsc then if the coil is split the two will try and level out.

Ok thanks. Any easy way for me to check the coil?

 

[Riley]

That’s what I just said?? If the f&e is higher than the cwsc then if the coil is split then the water levels in the two tanks will try and level out

 

[Riley]

The test is, is the f&e water level higher than that in the cwsc

 

[GGg]

Sorry. Get you now. Will check.

So. Sat in the attic whilst the mixer taps where tested. Felt the feed at the bottom of the cw tank and it was sucking the water out quite powerfully, nothing being pressed back up?

The valve has now settled and the water is the correct level.

But in a day or so it will be overflowing again. I’m completely baffled. Picture of the F&E tank just in case I’m missing something obvious.

Where’s the f&e tank? Or is that the f&e tank?? I think you’re missing my point where is it in comparison to the cwsc
