Water, wells, and septic

Map every home water-treatment device and filter stage

A home may have a refrigerator cartridge, under-sink stages, whole-house housings, a softener, reverse osmosis, UV, or well treatment, each with a different part, date, and safety boundary.

Homeowner guidance with clear stop points

When it usually needs attention

Usually repeats every 1 year

Domoranda uses a yearly stage-inventory review so added cartridges, bypasses, refrigerators, or service changes do not disappear from the care map; record changes sooner whenever the system changes.

When this guide applies

Applies when any whole-home or under-sink water-treatment equipment is confirmed.

What to do

Trace only safely visible treatment equipment and record each device, cartridge, membrane, lamp, tank, or service point as its own home item with a location. Link stages to parent equipment when known and leave brand or model blank when unknown.

Applies when: Applies when any whole-home or under-sink water-treatment equipment is confirmed.

Who should handle it: Residents may document safely visible labels and locations; owners, plumbers, certified treatment providers, laboratories, and utilities control pressure, sanitation, treatment claims, and internal service.

Tools

  • Phone camera
  • Flashlight
  • Existing treatment diagram, water report, or service record if available

Parts and supplies

  • No cartridge, salt, lamp, membrane, sanitizer, or test chemical until the exact stage and instructions are confirmed

Safety gear

  • None for ordinary visible documentation; stop instead of opening pressurized or energized equipment

Before you start

  • Keep drinking-water and medical-use needs in mind
  • Treat every replaceable stage and refrigerator as a separate location

Power, water, or fuel shutoffs

  • Identify safe water and power controls from documentation, but do not operate an unfamiliar bypass, valve, pressure vessel, UV unit, or pump solely to map it

Cleaner or chemical limits

Do not open, sanitize, descale, or add bleach, vinegar, solvent, degreaser, or another generic chemical while mapping the system.

Stop and get help when

  • Stop for leaks, pressure, wet electricity, UV exposure, contamination concern, sewage, damaged housing, unknown chemical, or a treatment claim you cannot verify
  • Do not open a well cap, pressure vessel, service panel, membrane housing, or stuck filter housing

Who to call: Use a qualified plumber, certified water-treatment provider, laboratory, utility, public-health authority, or well professional appropriate to the equipment and concern.
