I've got a Wellmate SP-9 Hydropneumatic pressure tank to replace my older galvanized Hydropneumatic tank.
The plumbing directions that came with the new tank state that a check valve should be installed before the inlet of the pressure tank before the pressure switch and other items.
My current galvanized tank does not have a check valve installed and is using the (I'm guessing) 50yr old plumbing. I also heard from a local (Milwaukee area) plumber that it is against code to have a check valve installed. If there were a problem with the line running from the well to the tank, it could allow leeching into the line since there would be no pressure.
That didn't quite make sense to me though as there would be a foot valve at the pump effectively checking the system correct?
I'll admit that I'm not real knowledgeable about these systems. Not sure what sort of device I have in the drop line letting air into the system if that makes a difference.
What is the correct way to install this tank?
Thanks.
