Dielectric Union?

If you do decide to use this system be sure to replace your supply lines under the sink with the braided style supply lines. You will need 4 for each bypass valve. If you don't, I guarantee they will leak!!! Also, the pump comes with only one bypass valve (it is only about 1" X 3" in size). You will need one more bypass valve for the other run.

Thanks for the info Jason. Very helpful.
Have you ever seen the passive (no pump) type used?
The wife keeps telling me it takes to long to get Hot to the fixtures so I guess I better get busy on this litle project.

No I have not. I will have to check into them. Any idea of where I can look for them on-line?

The Grundfos Retro-fit system works well though. I have installed it for a customer and I even went back to the customer to find out how it has been working out for them. They praised it.

The customer had a 16' tall ceiling in their 80' long walk out basement. I didn't want to deal with moving a large ladder that much.

JustRight makes one. It does require a recirc line from the farthest fixture though. I thinks NIBCO sells them.
