Reverse osmosis system maintenance checklists
Reverse osmosis system maintenance checklists for the quarterly and annual rounds: 2 free lists, 29 items and 27 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 reverse osmosis system rounds
Where each walk sits in the schedule
01quarterly
Reverse osmosis system quarterly maintenance checklist
Every quarter, since a loaded prefilter starves the pump and a fouling membrane both show up here before product quality falls off.
Run by: The water-treatment or plumbing tech on the quarterly round of the RO skid.
02annual
Reverse osmosis system annual maintenance checklist
Once a year, when the skid can be taken down for the clean-in-place or membrane change and the storage tank can be drained and re-charged.
Run by: The water-treatment service tech on the annual service of the RO system.
What most often fails on a reverse osmosis system
- 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.
- Membranes replaced or cleaned but the storage tank's air charge never checked, so short-cycling and poor draw-down carry on.
- Flush or clean-in-place cut short before the rinse runs clear, leaving cleaning chemical in the vessels to reach the product line on restart.
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.

- Which standards is reverse osmosis system 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 (29 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.
