Water Leak.

[aryan57]

Can anyone offer information about water meters please?

My last quarterly bill was over double that of the previuos three months so I decided to look for any leaks. My water meter has a small black cog in the middle under the glass. I pressume that if this continues to go around when nobody in the house is using water, then it means that there is a leak somewhere. When I turn off the house stopcock, then the meter cog also stops going round. So the leak must be in the house somewhere. I have been unable to find any major leaks.

My question: How sensative is the little black meter cog? The movement of the little black cog reminds me of watching the second hand on an electric clock ticking over.

In terms of water loss, what would the movement represent?

They are very sensitive.

Most likely a loo overflowing internally.

If you have an internal stopcock then turn that off and if it is still going round then that means your leak is underground between your water meter and internal stopcock.

Thank you, gentlemen. I have today found 2 taps leaking gently underneath a hand basin plus a weep under a radiator valve pipe. Now the little black cog remains stationary. It does indeed seem to be very sensative. Thanks again.
