Will be returning
The dielectric sleeves are brittle plastic. They broke upon installation. I'm returning them and will try webstone.

Best Option
You need flanges....you know you will need to replace the pump in the future...why the heck would you not use isolation flanges to get the job done right next time.
I also like the fact that I can trim down on the discharge side of the pump to calm down the noise the pump may make in a small system.

The valves work fine but ...
These valves work fine but....If you need to replace a gasket when you change a circulator - they are hard to find and non standard.

Usual high quality from Grundfos
Purchased to pair with a Grundfos hot water re-circulation pump Alpha 15-55sf. Top quality works smooth.
