Water problems in a rental often start as a passing remark. The tap runs cloudy for a day, the kettle crusts over, or a shower door never looks clean no matter how hard you scrub. In a St. Louis rental, where the water comes from the regional supply and the plumbing may be decades old, these small signs are easy to dismiss. A written record turns them into something a landlord can act on, and it protects you if the issue grows later.
This guide is about the paper trail, not a debate. It covers how to describe what you see, how to put it in writing, and how to keep track of responses. It is a reader resource, not legal advice, and the details of your lease and local rules will matter.
Start with a simple log
Before writing to anyone, keep a short log for a few weeks. Note the date, the room, what you noticed, and what you did about it. Useful details include:
- Color, cloudiness, or sediment in the cold tap or hot tap
- Odor or taste, described plainly, such as metallic, earthy, or chlorine-like
- Stains on sinks, tubs, toilets, or glassware
- Scale on faucet aerators, shower heads, or kettle elements
- Whether the problem happens at one fixture or throughout the unit
- Whether it changes after heavy rain, a water main repair, or work on a neighboring property
Photos help. Take them with a timestamp, and include something for scale, like a coin or a ruler, when you photograph deposits or staining.
Testing before you claim a cause
You do not need to diagnose the water yourself, and you should avoid guessing at what is in it. Simple home test strips can show general hardness, and a certified lab can test for specific substances if a question comes up. Keep results with your log. If a test was done by the landlord, a utility, or a lab, ask for a copy of the full report, not just a summary sentence.
Separate what you observed from what you think is causing it. 'The hot tap runs rusty-colored for about ten minutes every morning' is a useful statement. 'The pipes are corroding' is a conclusion that may need an inspector or plumber to confirm.
Write the request
A written request, sent by email or through the landlord's maintenance portal if your lease uses one, creates a date and a record. Keep it short and specific:
- Your name, unit address, and the date you first noticed the problem
- A plain description of what you see, smell, or taste, and where
- The log dates or photos you are attaching
- What you are asking for, such as an inspection, a water test, or a repair date
- A reasonable response date, and a note that you are keeping copies
Avoid adding opinions about the water's safety or accusing anyone of anything. A calm, factual note is easier to act on and harder to dismiss.
When the answer is that it is a softener issue
Some landlords in St. Louis say hardness is normal for the area and that a softener, filter, or cleaning routine belongs to the tenant. Ask whether a softener or filter is installed, who owns it, and who is responsible for servicing it. Your lease may answer this directly. If it does not, ask the landlord to put the responsibility in writing. Do not start paying for or changing equipment you do not own without a written agreement, and do not move or disconnect anything without asking first.
If the issue affects only one fixture, cleaning or replacing a faucet aerator may solve it, and you can list that as a shared first step in your request.
Keeping the trail going
Save every email, text, and portal message. If a phone call happens, follow it with a short written summary to confirm what was said, such as the date of a visit or the agreed next step. Keep a copy of the lease and any inspection report.
If the landlord does not respond, or the problem continues after a repair, your city or county housing or health inspection office can explain how to file a complaint for your address. Rules differ between the City of St. Louis and St. Louis County, so confirm which office covers your rental before you file. A good log and a clear written request usually make that process faster.
