How much pressure are you planning to put on it? -Kyle M @ Aero
From: [email protected] <[email protected]> Sent: Tuesday, November 4, 2025 8:18 AM To: [email protected] Subject: [External][Sprinklerforum] fire pump underground valve is leaking We want to try to fill the suction side of Pump #1 with water and if the suction pressure gauge at the suction shows holding pressure, it is basically closed. If it loses pressure, it’s open to some degree. Any risk associated with filling pump this way. See pic.
