This is a completely new installation. I know that circulators should be mounted such that the shaft is horizontal. I know where in the plumbing to install the pump (pumping away). How does one actually install the plumbing around a pump? Do I bolt the pump to the flanges (with the o-rings) and then install it as a unit already bolted? Obviously the spacing between the flanges has to be right. It seems like I don't want to tighten the bolts after the plumbing is installed and apply the torque on the plumbing forever, though the require movement ought to be very slight.
Thanks for any comments!
