When something goes wrong under a St. Louis kitchen sink, the person who comes to look at it has to figure out the setup from scratch. A simple home record makes that visit shorter and keeps everyone from guessing. This guide covers what to write down and photograph so your reverse osmosis setup is easy to explain, whether you are calling a service provider, talking with a landlord, or handing the job to another adult in the house.
Start With Photos
Open the cabinet doors, turn on a light, and take clear photos of the whole area. Stand back far enough to show the full unit, then move in close on each connection so the fittings and tubing can be seen. Photograph the storage tank if you have one, the faucet from the front, and the drain connection. Keep the phone steady so any printed labels can be read later. Save the pictures in a dedicated folder and in a cloud account you already use, so they stay available even if the phone is lost or replaced.
Write Down the Basics
A short written note goes a long way. Include the date the system was installed, the date each filter was last changed, and whether the unit has a storage tank or is a tankless design. Note where the home's main water shutoff is and where the unit's own shutoff valve sits. If you do not know what type of pipe feeds the sink, write that down instead of leaving the field blank. A clear list of what you know and what you do not know saves time when someone asks.
Record Your Water Source Information
Most St. Louis homes are served by a municipal water system, and many homeowners receive an annual water quality report from their provider. Keep a copy of the most recent report in your file. Mark any sections you found confusing so you can ask about them later. Also note whether your home has a water softener, a sediment pre-filter, or a whole-house filter, and where each one sits relative to the reverse osmosis unit. The order of equipment matters when someone is trying to understand a drop in flow or a change in taste.
Track Service and Changes
Keep a simple log in a notebook or spreadsheet. Each entry should include the date, what was done, who did it, and any notes about how the water looked, tasted, or flowed afterward. Add filter changes you did yourself. Over time, the log can show patterns, such as a faucet that slows down shortly before a filter change is due. Those patterns are much easier to spot on paper than from memory.
Keep the File Where Others Can Find It
Place a paper copy in a labeled folder near the water heater or the main shutoff, and tell another adult in the household where it is. Renters should keep a copy too and share it with their landlord when reporting a problem. If you use a property manager, ask them to add your notes to their records. A shared file means a repair visit does not depend on one person remembering every detail.
What to Do When a Visit Is Needed
- Pull up your photo folder and written log before you call.
- Describe the symptom in plain words, such as a slow faucet, a leak under the cabinet, or a change in taste.
- Note when the symptom started and whether anything else changed in the house, like a new appliance or recent plumbing work.
- Ask whoever comes out what they found, then write the answer into your log.
Keep It Simple
You do not need a complicated system. A folder, a notebook, and a habit of taking photos whenever you open the cabinet are enough. The goal is to make the next visit faster and clearer for everyone involved, from the person working on the unit to the homeowner trying to understand what is happening in their St. Louis kitchen. Update the file every time something changes, and review it once a year when you check your filters.
