Cold Bath Tap

I'm a confident DIYer & in the process of updating the bathroom & therefore changing all fitments. They have all been removed. However during the process of removing the bath I went through the following process.
1. Main house stopcock turned off
2. Both red stopcocks on the hot water tank turned off
3. Ground floor(kitchen) hot & cold taps opened.
All flow through all taps stopped with the exception of the bath cold tap which had a small constant flow of water. This flow was not under pressure.
Bath has been removed OK and taps replaced back onto pipes as a temp measure. My question is where is this water coming from?. When I come to refit the taps I would prefer to have NO water running out of this cold pipe for obvious reasons.

could be you've got a cold water tank feeding the bath ?

If you can't manage to work out where it's coming from, you could install a full bore isolating valve. Should be easy enough to do even if there's a slight trickle of water, and won't restrict the flow/reduce pressure.

Thanks for the quick replies. Unable to trace source last night other than the flow is gravity fed. I must add that the flow is NOT a drip but a slow constant feed.
ChrisOxford it was my intention to use flexible connectors with built in iosolating valves rather than a straight isolating valve. Can I therefore take it that providing I use plenty of towels during the fitting of the connector that this will be ok

Probably.

If you have the flexi's valve open and direct the other end of it into a bucket while you're attaching it, should be OK.

Note that flexis will restrict the flow from gravity-fed supplies, so you might want to think again!

Flow reduction. Is this due to the flexi's having a smaller bore Will both cold & hot feeds be affected if I use them
