In response to Re: Recirculating pump-not circulating?
The water should be circuling through whatever section of piping it is attached to. But, unless they piped the hot water system to all the areas in a loop the pump will just keep those faucets in the loop hot. Any faucets that have their supplies piped to the loop or directly to the water heater will take longer to get hot water. It is also possible that there is an air bubble in the circulating piping that needs to be purged. The pump will not circulate if the pipe is not full of water.

: We just recently move into our new home. We have a recirculating pump on the hot water heater. It is a 2 story, approx. 3100 sq. ft. I had the plumbing contractor replace the first pump, as it wasn't working. The new pump is a few days old, and doesn't work that great at all. The contractor said this is the best it will do. So much for the "instant hot water" that they said it would give.....The closest sink to the hot water heater takes 25 seconds, and the farthest faucet takes 1 1/2 minutes. I thought that the hot water was constantly cycling through the plumbing. Am I right? Or is does this sound normal?
