First of all, great site! I found this forum some years ago when I started having to trouble shoot my Grundfos VFD due to the shortsighted engineered obsolescence of this type of system (I fell victim to the promises of greater efficiency with VFD when my conventional well pump failed after some 20 years). After 2 CU301 controllers failed (the first being replaced under warranty), I converted by system over to one utilizing a CSV, and never looked back.
Today, my 4.4gal pressure tank has become water logged (the tank that was gleaned from the Grundfos VFD system when I converted my system over). My local plumbing supply house has an Amtrol ProFlo thermal expansion tank (water heater safety tank) that sure seems like it can be used for my application. I mean, logically, it does what I need it to do. It operates in the same pressure ranges as my old tank, it has a bladder with air on one side and water on the other, what else is there? Amtrol customer (no)service was no help. I've poured over this site, and the internet, to determine if there's any reason why I CAN'T use this tank, to no avail. Just looking for verification from those in the know....
