What does this backflow prevention assembly quarterly checklist cover?

13 items across 4 sections, covering visual condition, enclosure and freeze protection, signage and access, records and reporting. Each item spells out what the person walking the job is actually looking for, not just a box to tick.

Who should run this inspection?

The plumbing or fire protection service tech on the contracted quarterly visit.

When in the schedule should this walk happen?

Every quarter, with extra attention to freeze protection when the assembly is exposed and winter is approaching.

Why do these items ask for a photo?

7 of the 13 items call for photo evidence, 8 photos in all. A checklist answer without the photo is a claim; the photo is what makes the record worth something in a dispute and lets a reviewer approve work without re-walking the job.

What most often fails a backflow prevention assembly quarterly inspection?

Test cocks left weeping for months because 'it's always done that' without anyone tracing the cause. Enclosure heater found unplugged or tripped going into winter, risking a freeze split. Shutoff valves found only partially open with no one noticing the reduced flow.

Can I use this checklist in RTI?

Yes. Start a free RTI workspace, build this list as a checklist, and the Photo Gate holds the submit button until every mandatory item is answered and its photos are attached. Approved inspections roll into a branded turnover package with a tamper evident audit trail.

Backflow prevention assembly quarterly maintenance checklist

A quarterly backflow preventer round is short on purpose: it catches the wear items that fail between annual services. This checklist is sized for a tech with a phone. Every item says what to look at and the photo that proves the round happened. Work is commonly verified against the local water authority requirements, ASSE guidance. Confirm the edition your authority having jurisdiction has adopted.

The checklist

Every item, and the photo evidence it needs

The photo count on each row is what RTI would require before the item can be submitted. Work the list here and watch the gate hold, or load it into RTI and let it enforce the real thing.

Visual condition

Shutoff valves confirmed fully open
Both upstream and downstream shutoffs fully open and free to operate, not partially closed.
Assembly and test cocks checked for leaks
No dripping or weeping at test cocks, relief port or body seals.
Relief port watched for spitting or steady discharge
On reduced pressure assemblies the port stays dry at steady flow; intermittent or constant discharge is reported for the certified tester.
No photo
Drainage below the assembly checked clear
Air gap funnel, floor drain or grade below the assembly open and flowing, so any discharge leaves the room or pit without flooding it.
Assembly supports and piping alignment checked
Assembly carried on its own supports, no sag or strain at the flanges or unions, and no impact damage from traffic or equipment.

Enclosure and freeze protection

Enclosure or pit condition inspected
Cover secure, drainage clear, no standing water or debris around the assembly.
No photo
Heater and insulation checked in cold-weather locations
Heater plugged in and functioning, insulation intact, no exposed piping ahead of a freeze.
No photo

Signage and access

Identification tag and signage present and legible
Tag shows assembly identification, size and last test date, still readable and attached.
Access for testing confirmed clear
Test cocks reachable without moving stored material, ladder or panel access unobstructed.
Assembly nameplate matched against the building records
Make, model, type, size and serial number cast or tagged on the body match the backflow records held for the building.
Next test due date checked with the owner
Last test date compared with the water purveyor's schedule, and an overdue or soon-due annual test reported to the owner for booking.
No photo

Records and reporting

Latest certified test report confirmed on file
The most recent annual test report and its submission to the water purveyor are in the building records, or the gap is reported.
No photo
Quarterly findings reported to the owner
Leaks, relief discharge, freeze risk and access problems written up for the owner, with anything needing the certified tester flagged.
No photo
