    We are getting a noise behind the bathtub taps. We have recently had real cold weather (-17 degrees), and the noise became apparent then. It doesn't sound like running water to me - although my wife disagrees. To me it sounds more like water pressure of some sort. There doesn't appear to be any water leaking anywhere - the mains taps are in a bedroom cupboard...there is no leaking water in there. The noise is there whether the mains are on or off - we have tried it both ways.

    Also, the water meter appears to have stopped regulating the water flow.

    Can anyone shed any light on this?

    Thanks,

    Steve

    With all taps off in the house, look at the water meter, note the reading, then wait an hour or so to see if it moves. You may have a small leak.

    The water meter only measures the flow, it does not other function. Not sure what you mean about 'stopped regulating the flow'. There may be a valve near the water meter, and depending on the type and its status, it may no longer turn the water off. This can be a pain, and that valve may need to be replaced. Depending on its location, and how things were plumbed, you may need to get the utility to shut your water off at the street to effect a repair.

    Keep in mind that when you shut the water off, the system is still under pressure until you open a valve to relieve it. There still could be a small leak.

    Do you get flow from all of your faucets? Did any of them stop during the cold snap? If they did stop, it's likely things froze. That often will cause a leak when the ice melts.

    When it gets cold mice and similar critters look for a warm place. Sometimes they will go in holes around pipes and make a nest. You may need to seal those areas up with metal flashing. Moth balls may discourage them.

    It could be expansion sounds from a vent pipe or drain pipe pressing against a tight hole. Hard to tell. I did a poor job of drilling a 2" vent line hole and listen to clicking sounds for 2 years before I busted open the wall and opened up the hole for the vent line.

    Do you access to a thermal camera. You might rent one to put the worst case scenario possibility to bed.

    Look for images like this....

    This picture shows leaking and water concentration between the sheets of the backer board. Most likely 3'x5' cement board shown. You might need to look below your room for a leak if it is inside rthe wall.

    Maybe an image like this will help you find the problem quickly

    It turns out it was a leaking pipe outside - underground. We have got a company coming out on monday to repair it. $2700. At the moment we have got water seeping out above ground. The local utility company said we are losing about a gallon a minute. We are getting it fixed soon.

    I guess good news and bad news all at the same time.

    How did you find the leak? Did you end up using a thermo imagining camera?

    Thanks for the news update. What did they charge you to find this leak? I would love to know more about the service they offered....

    Did you see them use a thermal imagining camera or moisture probe sensor?
