Reverse osmosis system quarterly maintenance checklist
A quarterly reverse osmosis system 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 manufacturer's published instructions, IPC / UPC plumbing codes. Confirm the edition your authority having jurisdiction has adopted.

Who runs it
The water-treatment or plumbing tech on the quarterly round of the RO skid.
When in the schedule
Every quarter, since a loaded prefilter starves the pump and a fouling membrane both show up here before product quality falls off.
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.
Prefiltration
- 2 photos
Sediment prefilters checked and pressure drop noted
Cartridge or housing condition checked, inlet-to-outlet pressure drop across the prefilters read and compared to a clean set.
- 1 photo
Carbon stage condition and interval verified
Carbon cartridge or bed within its service life, no channeling or bypass, dechlorination stage protecting the membrane confirmed in place.
Membrane performance
- 2 photos
Operating and permeate pressures read at the gauges
Feed, concentrate and permeate pressures read off the skid gauges and compared against the unit's normal operating range.
- 2 photos
Permeate flow and product-quality reading observed
Permeate flow and the product-quality meter observed and logged as displayed, trended against the last visit — the reading is recorded, not judged against an invented limit.
Pump and leaks
- 1 photo
High-pressure pump running normally
Pump holding pressure without cavitation noise, vibration or overheating, no cycling on a starved inlet.
- 1 photo
Skid, housings and fittings checked for leaks
No weeping at housing seals, membrane vessel end caps or fittings, no moisture tracking under the skid.
What usually sends this back
The failures are almost always the evidence, not the work
- Prefilters run past their change interval, so the high-pressure pump pulls against a starved inlet and the whole skid loses output.
- Product-quality meter glanced at but the reading never logged, so the slow climb that signals a failing membrane is invisible.
- A carbon cartridge left in past its capacity, letting chlorine reach and damage the membrane it was there to protect.
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 reverse osmosis system quarterly checklist cover?
- 6 items across 3 sections, covering prefiltration, membrane performance, pump and leaks. 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 water-treatment or plumbing tech on the quarterly round of the RO skid.
- When in the schedule should this walk happen?
- Every quarter, since a loaded prefilter starves the pump and a fouling membrane both show up here before product quality falls off.
- 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 reverse osmosis system quarterly inspection?
- Prefilters run past their change interval, so the high-pressure pump pulls against a starved inlet and the whole skid loses output. Product-quality meter glanced at but the reading never logged, so the slow climb that signals a failing membrane is invisible. A carbon cartridge left in past its capacity, letting chlorine reach and damage the membrane it was there to protect.
- 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.
