Details to Provide When Scheduling

• Serial or model number visible on the backflow preventer body or adjacent shutoff valves.
• Approximate static pressure reading taken at an outdoor hose bib if a gauge was used.
• Which fixtures show reduced flow after the main isolation valve or pressure reducing valve.
• Whether the water heater is tank or tankless and its distance from the backflow assembly.

Steps to Protect the Supply While Waiting

• Leave all test cocks and isolation valves in their current positions so hydraulic pressure across the checks remains stable and no reverse flow path opens to the potable line.
• If active leakage occurs at the relief port, place a bucket beneath it rather than attempting to adjust the downstream shutoff, preserving the air gap that prevents backsiphonage.
• Clear any stored items from the device area to allow direct access to the number two check valve and relief valve without moving hoses or creating new cross connections.
