Hot water recirculation pump quarterly maintenance checklist
A quarterly recirculation pump 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 IPC / UPC plumbing codes, manufacturer's published instructions. Confirm the edition your authority having jurisdiction has adopted.

Who runs it
The plumbing or building maintenance tech on the quarterly mechanical round.
When in the schedule
Every quarter, paired with the water heater check since a dead recirc pump shows up first as slow hot water at the far fixtures, not at the heater.
The checklist
Every item, and the photo that proves it
The photo count on each row is what RTI would require before the item can be submitted. Copy the list as is, or load it into RTI and let the gate enforce it.
Leaks and operation
- 2 photos
Seal, flanges and body checked for leaks
No weeping at the pump seal, isolation flanges or unions, no rust trail or drip under the circulator, motor and body dry.
- 1 photo
Pump running and moving water quietly
Circulator energized when the controls call, running without growl, cavitation gurgle or excessive vibration, a temperature rise felt across the pump confirming it is actually moving water rather than dead-heading.
Check valve and controls
- 1 photo
Check valve holding against reverse flow
With the pump off, the return line does not thermosiphon hot the wrong way, and with it on the flow is in the intended direction, no sign of a check stuck open or chattering.
- 1 photo
Aquastat, timer and controls set as intended
Aquastat setpoint and any recirculation timer schedule confirmed against the intended settings so the pump maintains the loop through occupied hours rather than sitting idle.
Delivered temperature
- 1 photo
Return temperature verified on the loop
Actual return-line temperature measured near the pump and compared to the setpoint, confirming hot water is being carried back rather than the loop running cold between calls.
What usually sends this back
The failures are almost always the evidence, not the work
- Pump seized or tripped and nobody notices, because the slow hot water at the far rooms gets blamed on the heater instead of the circulator that stopped moving water.
- Check valve stuck open, so hot water thermosiphons the wrong way through the loop and the return leg reads cold even with the pump running.
- Aquastat or timer set so the pump almost never runs, so the return temperature is read once, called fine, and the loop sits cold for most of the day.
Run it with the Photo Gate
A checklist nobody can submit half-finished
Load this list into RTI, stick a QR tag on the area it covers, and the submit button stays locked until every mandatory item is answered and the 6 required photos exist. Approved walks roll into a branded turnover package with a tamper-evident record behind every line.
Submission state
The gate is enforced on the server, so it holds even if the phone is offline when the walk happens.

Common questions
- What does this hot water recirculation pump quarterly checklist cover?
- 5 items across 3 sections, covering leaks and operation, check valve and controls, delivered temperature. 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 building maintenance tech on the quarterly mechanical round.
- When in the schedule should this walk happen?
- Every quarter, paired with the water heater check since a dead recirc pump shows up first as slow hot water at the far fixtures, not at the heater.
- Why does every item ask for a photo?
- 6 of the 5 items call for photo evidence. 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 hot water recirculation pump quarterly inspection?
- Pump seized or tripped and nobody notices, because the slow hot water at the far rooms gets blamed on the heater instead of the circulator that stopped moving water. Check valve stuck open, so hot water thermosiphons the wrong way through the loop and the return leg reads cold even with the pump running. Aquastat or timer set so the pump almost never runs, so the return temperature is read once, called fine, and the loop sits cold for most of the day.
- 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.
