Your mother says the sump pump is working. You can hear a motor during a phone call, and the basement floor looks dry on video. That is useful, but it does not tell you whether the pump starts at the right water level, sends water away from the house, or will receive attention when something changes.

Your job from far away is not to become the basement mechanic. It is to establish what equipment exists, what a successful test looks like, who performs that test, and who gets the first call when it fails. FEMA guidance treats sump pumps and backup power as parts of household flood preparation. The pump manufacturer’s manual supplies the operating and maintenance instructions for the actual unit. St. Louis sewer and emergency agencies supply local information about drainage, sewer problems, and reporting routes. The public-source trail used by this desk is collected on the Sources page.
1. Identify the whole system, not just the pump
Ask someone in the house to photograph the pit with its cover in place, the pump and float inside if they can be seen safely, the electrical plug, the discharge pipe, every alarm or battery box nearby, and the place where the pipe exits the house. Do not ask anyone to reach into water, remove wiring, or open sealed electrical equipment.
Have them photograph the manufacturer label and model number. Look for one pump or two, a separate high-water alarm, and any battery backup. A second device beside the pit may be a backup pump, an alarm, or something unrelated. Confirm it from the label instead of guessing from its shape.
Save the manual that matches the model. The manual should settle which test is allowed, what indicator lights mean, which parts need attention, and who is permitted to service the unit.
2. Trace where the water goes
A pump can run while sending water to the wrong place. Ask your local person to follow the discharge pipe without disconnecting it. You need a photo of the outside outlet and a wider photo showing its position relative to the foundation, steps, walkways, and neighboring property.
Check whether the outlet is attached, unobstructed, and directing water away from the house. Look for crushed extensions, loose joints, standing water beside the foundation, and water returning toward the basement. Do not assume a buried pipe is clear because the visible end looks tidy.
If the discharge appears connected to household plumbing or a sewer line, leave that question for a qualified local contractor or the appropriate sewer authority. Connection rules and site conditions cannot be established from a video call.
3. Define a safe test
Use the manufacturer’s instructions for the specific pump. Some systems can be tested by adding clean water to the pit until the float activates. Others have a test control or a different procedure. Your mother should not perform the test if reaching the pit requires stairs, lifting a cover, carrying water, or balancing near an open hole.
The local tester should observe four separate results: the pump starts, water in the pit drops, the pump stops, and discharged water appears where expected outside. Record a short video that includes the pit before activation, the running sound, the falling water level, and the outside discharge.
A motor sound alone is not a passed test. Neither is a dry pit. Write the successful result in plain language so the next person knows what to reproduce.
4. Give the routine test to one owner
“We check it” is not ownership. Put one person’s name beside the recurring test. That person might be a relative, neighbor, handyman, plumber, or local home-check service. Ask whether they will enter the basement, follow the manual’s test, inspect the outside outlet, and send proof afterward.
Let the manual and local conditions set the testing rhythm. Add an extra check after electrical work, plumbing work near the pit, a long vacancy, or any event that changes the basement. Put the task on a shared calendar with a completion note, not merely a reminder.
If the named person cannot come, name the backup person now. A task without a substitute still belongs to you when the first person is unavailable.
5. Separate backup power from backup pumping
Ask what continues to work when household power is unavailable. A battery box does not prove that the pump has working backup power, and a second pump does not prove that it can run without the outlet.
Photograph the battery label, indicator panel, cables, and any written test instructions. Ask the owner of the routine test to confirm what each light or alarm means and to test the backup only as the manufacturer directs. Record who replaces the battery or services the backup, and where the replacement specification is stored.
If there is no backup, ask a qualified installer to describe the options that fit this pit, discharge route, electrical setup, and expected maintenance. Compare proposals by what will keep working, how it will be tested, what signals a problem, and who will maintain it.
6. Make alarms reach a person
A high-water alarm helps only if someone hears it and knows what to do. Identify whether the system sounds only inside the basement, sends a remote notice, or does both. Test the notification using the device instructions.
Write the alert route as a sequence: who receives the first signal, who acknowledges it, who can enter the house, and which service company is called. If the first person does not respond, the alert should move to a second person without waiting for you to notice a missed message.
Keep the alarm instructions with the model photos. Label notifications with the house address and device name so they are not confused with another sensor.
7. Build the repair call before you need it
Ask a local plumber or pump service what information they require before dispatch. Keep the address, access contact, pump model, pit photos, discharge route, electrical-panel location, and recent test record in one folder.
Clarify who can approve a visit, who will meet the technician, and how the technician will report findings to you. Ask for photographs of the failed part and the completed work. If replacement is proposed, compare the new pump’s fit, power source, capacity stated by the manufacturer, alarm connection, backup arrangement, warranty process, and future test procedure.
Do not let the old pump disappear before its model and failure are documented. That record helps you understand what changed and maintain the replacement correctly.
8. Keep a short proof record
Create one page with the equipment list, model numbers, manuals, named test owner, backup person, service company, access instructions, last completed test, and next scheduled check. Add links to photos and videos rather than scattering them through text messages.
After service, update the page. Record what was cleaned, adjusted, repaired, or replaced, who performed the work, and what the next test should confirm. Ownership means that the record survives a new neighbor, a different contractor, or your own busy week.
If you need someone in St. Louis to make the house check and send back usable proof, start with Local Help for a St. Louis Parent. Define the assignment as a safe inspection and documented test, not a general promise to keep an eye on the basement.
What to do tonight
Ask for six photographs: the covered pit, the visible equipment, every model label, the plug and outlet, the alarm or backup panel, and the outside discharge point. Find the matching manuals. Write down the name of the person who can safely perform the approved test and the person who can enter the house if an alarm sounds. Start the one-page equipment record even if several fields remain blank.
What to leave with the doctor
Leave diagnosis and treatment questions with the doctor. The sump-pump plan belongs with the people maintaining the house. If your mother cannot safely reach the basement, carry water, hear an alarm, use the stairs, or explain what happened, tell the doctor exactly what you observed and ask whether those changes affect the support she needs at home. Do not ask the doctor to certify the pump plan. Ask the local owner to remove your mother from any step she cannot complete safely.
