yeah i was going to go with this one:
https://www.supplyhouse.com/Grundfos-99412493-UP10-16-Hot-Water-Recirculating-Temperature-Pump-1-1-4-Union
looks like the check valve is removable.
but might go with this one and also looking at the Taco 003...
Got it. The pump has an internal check valve, should i still install the spring loaded check valve or is that an over kill/cause issues? Also, is this the boiler drain HERE?
Hello,
I'm adding a circulating pump to a dedicated loop line that is Pex A. I don't have the expansion tool so would like to use steel rings since I have the tool for that. My question, since Pex B fittings are smaller in diameter, will the flow restriction be noticeable? Thank you.
Hello All,
I'm trying to add a recirculating pump to my water heater. Dedicated return line already there from builder. Is my placement in the picture below look correct? Am I missing anything? Also, is better or don't matter if I use the cold supply or tank drain to tie the return to? Thank you!
