Re: Recirculating Pump
That sounds like a retro fit pump on a system that was not built with a return line when the home was built. The best type is one that has a return line that returns the water to the cold water line. This would then leave the drain port open for use.
As for draining the WH. Folks still do that? Honestly I have never drained a water heater in any of the homes I have owned over the past 25 years. Never had a problem with sediment building up and my gas water heaters have been lasting about 12-15 years before they need to be replaced. I know that some folks swear by draining water heaters every year, I just have not seen the need to do it.
I guess if you ever did need to drain a WH that has a recirculating pump on it you could just disconnect it.
This is a diagram of a typical system that you are talking about.
