Domestic water booster pump quarterly maintenance checklist
A quarterly booster pump set 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, so a drifting setpoint or a lag pump that never comes on is caught before upper floors start losing pressure at peak draw.
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.
Pressure and setpoint
- 2 photos
Suction and discharge pressures read against setpoint
Suction and discharge gauges compared to the target setpoint, transducer reading tracking the gauge, and a top-floor fixture opened to confirm real delivered pressure.
- 1 photo
Set holds pressure through a draw without hunting
Pressure stays inside the control band as a fixture is opened and closed, no rapid hunting or wide swing that points at a tank or transducer problem.
Sequencing
- 2 photos
Lead-lag hand-off observed
Demand raised enough to stage the lag pump in and back out, confirming the controller sequences rather than leaning on one pump.
- 1 photo
VFD ramping smoothly where fitted
Speed ramps up and down with demand instead of snapping between stops, no fault or alarm standing on the drive display.
Leaks and tank
- 2 photos
Seals, fittings and manifold checked for leaks
No weeping at the mechanical seals, unions or the manifold, no puddle or rust trail under the skid.
- 1 photo
Bladder tank pre-charge sound
Tank not waterlogged, no water at the air valve, set not short-cycling on small draws the way it would with a dead tank.
What usually sends this back
The failures are almost always the evidence, not the work
- Discharge pressure read on the gauge and called good while the upper floors are actually starving, because no one opened a fixture on the top level.
- Set runs on the lead pump alone for months and nobody notices the lag pump never sequences in until the lead one trips.
- Bladder tank waterlogged, so the set hunts and short-cycles on every small draw instead of the tank absorbing it.
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 9 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 domestic water booster pump quarterly checklist cover?
- 6 items across 3 sections, covering pressure and setpoint, sequencing, leaks and tank. 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, so a drifting setpoint or a lag pump that never comes on is caught before upper floors start losing pressure at peak draw.
- Why does every item ask for a photo?
- 9 of the 6 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 domestic water booster pump quarterly inspection?
- Discharge pressure read on the gauge and called good while the upper floors are actually starving, because no one opened a fixture on the top level. Set runs on the lead pump alone for months and nobody notices the lag pump never sequences in until the lead one trips. Bladder tank waterlogged, so the set hunts and short-cycles on every small draw instead of the tank absorbing it.
- 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.
