Pressure-reducing valve station maintenance checklists
Pressure-reducing valve station maintenance checklists for the quarterly and annual rounds: 2 free lists, 27 items and 18 photo requirements, each item naming what to look for and the photo evidence it needs. Work is commonly verified against IPC / UPC plumbing codes; the edition in force is the AHJ's call on each project.
The pressure-reducing valve station rounds
Where each walk sits in the schedule
01quarterly
Pressure-reducing valve station quarterly maintenance checklist
Every quarter, and any time upper-floor fixtures start complaining of low pressure or banging, which points back to the station.
Run by: The plumbing or facilities tech on the quarterly round at the PRV station.
02annual
Pressure-reducing valve station annual maintenance checklist
Once a year, when the station can be isolated section by section so the relief, bypass and each parallel valve get exercised.
Run by: The plumbing service tech on the annual station service.
What most often fails on a pressure-reducing valve station
- Downstream pressure read off a stuck gauge that hasn't moved in months, so nobody notices the valve is drifting past its setpoint.
- Strainer never blown down or pulled, so debris behind the PRV throttles flow and gets blamed on the valve.
- Seat wear ignored until the downstream pressure creeps up overnight with no draw, a classic sign the valve is passing.
- Relief valve on the reduced side never lifted, so if the PRV fails wide open the downstream piping has no real protection.
- Bypass valve seized because it hasn't been stroked in years, leaving no way to keep water on during a valve rebuild.
- On a parallel set the lead valve carries everything while the lag PRV is set wrong and never picks up, so one valve wears out early.
Verified against
Families only, never clause numbers. Adoption varies by jurisdiction; confirm the edition your authority having jurisdiction enforces before you run a walk against it.

Pressure-reducing valve station annual maintenance checklist (annual): Once a year, when the station can be isolated section by section so the relief, bypass and each parallel valve get exercised.
- Who runs the pressure-reducing valve station maintenance round?
- The plumbing or facilities tech on the quarterly round at the PRV station. The plumbing service tech on the annual station service.

- Which standards is pressure-reducing valve station work verified against?
- IPC / UPC plumbing codes, published by the International Code Council / IAPMO. Adoption varies by jurisdiction. Confirm the edition your authority having jurisdiction enforces before you run a walk against it.
- Can I run these checklists in RTI?
- Yes. Start a free RTI workspace and load any of the 2 lists (27 items in total). The Photo Gate holds the submit button until every mandatory item is answered and its photos are attached, and approved inspections roll into a branded turnover package with a tamper evident audit trail.
Run these lists with the Photo Gate.
Tag one area, scan it, and the submit stays locked until the photos exist.
