In your diagram (dedicated return line example) it is not clear where the water reenters the tank after the pump. It just shows a pipe going behind the thank. I have seen examples where the water is returned to the tank via the drain outlet at the bottom. However, your example doesn't seem to be done this way. What is your recommendation for connecting the return line to the tank? Thanks!
Hello there! Our pumps will always require connection to the return line. They can be placed in two different locations - either connected to the drain outlet or piped up to the cold water line. The main requirement is to have the pump hooked up to the return line close to the water heater.
I wanted to have the Alpha 15-55 HWR-D installed at my residence, but the plumber I contacted said that it is no longer available for sale in the US. Is this true? Thank you.
It is a product that is no longer being manufactured, that is true. There is some inventory still out there, at Supply House for example: gfos.ly/6050sT7YQ We recommend the new ALPHA HWR 15-58, however if you're needing the on-demand feature, you will need to look at the pump above.
@ Thank you for responding. I have just repiped and improved an existing dedicated hot water recirculating loop. I am looking for an “on-demand” system.
I have an older Type UP15-18 B5 pump with a timer on my dedicated 1/2 inch copper return line, unfortunately it no longer works. I would like to replace it with the same or similar pump, which one is the closest model?
Hello Colin, you can still find this pump in stock at some distributors. There is a link that will allow you to find a place to purchase on this page: gfos.ly/6055T4vuF Hope that helps! -Ty
I bough 595916 - Comfort System Hot Water Recirculation Pump - 3/4" NPT 115 Volt , my home have a dedicated return line, can I install it and not install the bypass valve. Thanks ! Paul
We're thinking that it's likely on 100% mode. Depending on your model, you can limit the pump running based on timer, temperature sensor, or AutoAdapt learning. Running on 100% is usually not a concern for this pump as it doesn't really use that much energy compared to things like a lightbulb. If you still have a concern, please feel free to get in contact with our support team: gfos.ly/6053r63WZ Hope that helps! -Ty
Hey there! It's not necessarily a newer pump, they are just different depending on the installation needs, such as sizing and if the application has a dedicated return line or not. The Comfort 10-16 is for systems with a dedicated return line, whereas the Comfort System (GRU-595916) is for retrofit applications that do not have a dedicated return line. Hope that helps! -Ty

Hello there, yes you can install that pump without the bypass valve!
What causes the pump to keep running. The motor is getting warm.

How does the Comfort 10-16 shown in this video compare to the Grundfos GRU-595916 product? Is the Comfort 10-16 newer?
