Black hue to water

Tango One

Hi

I notice the toilet water in my house has a slight black hue to the water in the toilet. I ran a bath and noticed it too. I think it's an internal problem don't notice it in the kitchen sink(main input) but would be harder to see against stainless steel sink.

Not sure if it related but had a leak at the boiler and a plumber put the liquid sealer which stopped the problem. Saying that I did have a leak of really dark black fluid from one of the valves at the boiler in the recent days.

Sounds like a badly constructed tank overflow or a leak in your cylinder coil.

Do you have a sealed system?

1 or 2 tanks in the attic?

One tank in the attic, there was two at one point but about 7 years ago I had the tank move and they didn't see the need for the second tank reducing it to one.

The house was build about 15 years ago and I only had a problem in the last few weeks. Not sure about the sealed system how could I tell.

Sealed system usually would have a red expansion vessel, a gauge and a means of adding water to increase the pressure.

Did plumber identify the place where the leak was?

I don't think it's a sealed system, I seen that red expansion in other houses and mine doesn't have it.

It was on the valves below the boiler. Minor enough of a leak, it was pricey enough to replace the valves and he wasn't sure the valves would match, so went with the sealer instead.

Time to get the plumber back.
