I'm hoping that someone can provide me with a flash of inspiration!
I am getting high TVC (out of spec) results at 22°C and 37°C from water samples, the high results have all come from handwash sinks with mixer taps.
The taps are clean, the water temperature coming out of the taps is >35°C, the water pressure is good.
There is a water storage tank but I have had this purged and treated a couple of months ago and the issue went away.
I'm at a bit of a loss; has anyone had similar issues?
Many thanks :)
