Boiler water fill Location

[Brian Murray]

I put my water fill on my new buderus boiler on the return side. My pumps and expansion tank are on the supply side. Should I move this to the point of no pressure change on the tank. I have low water cut off enabled so plan on shutting the valve on final fill.

What are your thoughts?

Ex tank and fill need to be on suction side of the pump. If fill valve is on a water regulator I'd wait a day or two before valving it off to get all the out of the system.
