Advice on white staining on brass stop tap

[Ozzpala]

Hi all just after a bit of advice, been in the subfloor to run wires and found stop tap coming in from the mains supply. We’ve been here 2 years and nothings leaking, we’ve found white deposits around this fitting. We’re presuming this is old or someone else previous may have got this fixed? The grounds dry and nothings wet. Insulation is also dry around the pipe and water meter hasn’t moved for 3 hours.

Is this one of them things you’d leave alone? This pipe runs downwards so the right side is higher than the left. It’s in the subfloor so it’s not exactly easily accessible so if I leave it I probably won’t be down here for another year or so

Just looking for somebody that may have a bit of knowledge on it

Thanks again

Looks like an historic small leak at the washer above has left a limescale deposit. If there is no sign now of moisture there I'd leave it alone.

Hi Alex thanks for that was thinking the same thing with it been historic don’t think I’m going to touch it. When you say it’s leaked from the washer above where do you mean ?
