I had new water heater installed last month along with a 2 gallon thermal expansion tank which something I didn't have before. The plumber said that the tank was required by code. Ever since the installation I've noticed that the water continues to run slowly at the meter sometimes for several minutes after the water is turned of at the fixture. Longer after heavy usage. This is something that wasn't happening before. I contacted the plumber, State water heater company and the water company none of them offered any helpful answers. I just replaced the the water pressure reducer valve because I had a leak at the pressure relief valve on the water heater. This stopped the leak but I still have the water continue to run at the meter after water usage. The only way I can get it to stop is if i shut off the valve above the expansion tank and water heater. Then, the water shuts off right away but as soon I open that valve the water continues to run. The expansion tank is a Wellsaver LPT-2 2 gallon tank and it is installed right above the water heater right after the shutoff valve. Can anybody tell what is going on here and is this something I should be concerned with? I can't find much information on the tank. Do they require regular maintenance? Is there anyway to check if it working properly?
thanks
