Water Heater Recirculating Pump Stopped Working


water heater recirculating pumpA water heater that uses a recirculating pump delivers hot water faster than a water heater without one. The pump pushes water through a loop installed throughout the house and allows hot water to be delivered to the fixtures much faster. The upside is that you don’t let a lot of cold water run down the drain, and the downside is that the heated water can give off a lot of its heat during it’s trip throughout the house. The water ends up back in the water heater at a lower temperature than when it left. I’m sure there are studies that say the water heater tends to run more due to this.

Anyway, if you’ve noticed that you are no longer getting near-instant hot water, check the pump. You might be thinking that the pump needs to be replaced, when the problem may be an easy fix. Certainly check to see that the outlet that the pump is plugged into is getting power. If it is not, it may just be a tripped GFI outlet that needs to be reset. The other possibility is that your pump may have a timer on it that is not set correctly. If there was a power outage your pump will be off for the amount of time that the power was out. Resetting the GFI outlet and checking the timer may solve your problem.



Hey Mike, 
nice blog.  
Another problem with circulators is aeroation. The pumb draws air into the line. Often, the air is introduced through valves that utilize a seat, cup and spring. What happens is the cup is actually drawn toward the seat of the valve and air is pulled in. Some times it sounds like gravel in the pump. That is actually the air bubbles collapsing against the surface of the gears used to pump the water. 
Im searching to build a network of bloggers I can add to my side bar, in exchange for my adding your blog, will you add mine to your side bar? I don't see that you have such a list. Please email back or leave a comment on my blog. Thanks Jim

How can I check to see if my hot water heater has a recirculating pump installed on it? If not how hard is it to install to an existing system?
