Bath cold water supply

[suse71]

Wonder if anyone can help. fitting a new bath. Isolated hot water and cold is not rising main although this is OFF. GATE valve has a label saying that it isolates bath cold water. This is also off

Water just keeps coming out. Yesterday it was a eventually down to a slow dribble. I put the taps into the pipes without the bath so I could at least get in without it dribbling constantly.
Came back to it today and water is coming out again but more this time. Where is the water coming from?

No water coming from any other taps. Throwing down with rain. Beginning to think I’m bathing in rainwater

Have you looked in the loft?

Gate valve not closing fully?

I think the gate valve must be faulty. But I don’t understand how the tank in the loft is being filled if the ruin main is off?

anyway. Sorted now. Just had to work around the dribbles. Buckets and towels!!

domestic gate valves can't be relied on to give a totally watertight seal, but they are good enough to stop the flow while you work. Their big advantage is that when fully open, they don't obstruct the flow of water.

If the loft tank was still filling, then most likely the stopcock you found did not cut off the incoming supply. Where was it?

Or maybe you did not fully drain the tank before closing the gate valve.

Stopcocks are designed to be very reliable, though they can seize if the are not wound open and closed from time to time. When you open your valves, wind them fully open, than half a turn closed. This reduces the risk they will seize.

Hi. The stop cock was next to the downstairs toilet and stopped the flow to all the other taps in the house. But. Thinking about it I don’t know if there wasn’t a little bit of flow as the cold water tap in the kitchen ran for a bit this morning even though the stop cock was off for 24 hours.

Stopcock could be passing.
