Does anyone have access to older Potter flow switch info? I have a 3” VSR-D, 80’s vintage to replace with a new VSR-F.
Nothing on their website. Wondering if the hole sizes are the same. Thanks, Thomas Duross The Fire Pump Testing Company 11 Varney Street Jamaica Plain, MA 02130 T 617-971-0700 F 617-524-7171 C 617-592-4236 [email protected]
