Reverse osmosis system maintenance checklists

Reverse osmosis system maintenance checklists for the quarterly and annual rounds: 2 free lists, 11 items and 17 photo requirements, each item naming what to look for and the photo that proves it. Work is commonly verified against IPC / UPC plumbing codes; the edition in force is the AHJ's call on each project.

Where each walk sits in the schedule

Reverse osmosis system quarterly maintenance checklistquarterly
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.
Reverse osmosis system annual maintenance checklistannual
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.

Common questions

Which reverse osmosis system maintenance rounds do these checklists cover?
Reverse osmosis system quarterly maintenance checklist (quarterly): Every quarter, since a loaded prefilter starves the pump and a fouling membrane both show up here before product quality falls off. Reverse osmosis system annual maintenance checklist (annual): 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.
Who runs the reverse osmosis system maintenance round?
The water-treatment or plumbing tech on the quarterly round of the RO skid. The water-treatment service tech on the annual service of the RO system.

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 (11 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.
