Problem with a water leak in a cold water supply line which is proving quite hard to find. It has resulted in two consecutive water bills of $400.
Closing the main valve where it enters the house, the noise of the leak stops. The city water meter stops as well.
It appears likely that it's the cold water line because placing your ear to the hot and cold pipes at various places in the crawl space, the leak noise is noticeably louder with the cold pipe.
There is no obvious water or moisture collecting in or under the house. There are no drips in the crawl space, that we have seen.
There seems to be no apparent leak at any toilet or faucet. We are aware of the food coloring test. There is no leak at the vertical stand pipe or vertical tube in any toilet.
It is dry around the base of the water heater. The water heater pop off is not leaking.
No exterior bibs are leaking per a visual check.
There is no pool or sprinkler system.
Done the screwdriver to ear, listening test, at all fixtures and can't really tell where it's louder.
The hot water heating system is supplied with a 1/2 water line. There are no leaks apparent on the boiler and no leaks apparent in the baseboard radiator piping. When you shut off the valve supplying the boiler, the leaking noise continues. The boiler pop off is not leaking.
Obviously we have missed something, because we still have a leak!!
If worse come to worse, we may have to resort to tracing the supply line around the crawl space and cutting and capping off the supply line until the flow stops. Though that would result in possibly quite a few couplings being installed. Naturally we'd prefer to avoid that.
Any suggestions would be appreciated!
