In response to Re: Water Lines Constant Running and Hot Water Backflow
: Recently we noticed the constant sound of running water in the bathrooms, but have found no evidence of leaks in or under (crawl space) the house. We did locate a leak in the main water line coming to the house (underground) and had it repaired, but this has not stopped the noise of running water. We have also noticed that both water lines to/from the hot water heater are hot when no hot water is being used. We turned off the water heater overnight, but the noise still occurs. The water heater is 12 years old. Are we dealing with a water heater problem, or do we still have a leak somewhere?

Problem solved: Actually two problems. The cold water line to the hot water heater runs under a 4' section of concrete. Even though there was no evidence of leaking, we bypassed that section of pipe. We ran new pipe from the hot water heater back to the existing exposed pipe in the crawl space. The sound of running water stopped which indicated a broken pipe under the concrete. The second problem was a bad thermostat in the hot water heater. It was replaced.
