max.rohr In reply to My Caleffi pressure regulator by David Sowar October 14, 2022 Hello David, I would check on the expansion tank. Double check that it also pressurized to 15 psi, when not in-line, and make sure it isn't waterlogged. Give us a call, if you want help walking through the steps. 414-238-2360 Reply
