If a toilet is overflowing or the water heater has quit, our 24/7 dispatch line takes the call and sends a licensed plumber from Maryland Heights. Same-day appointments are offered when available across Hazelwood, from the streets around City Hall on Elm Grove Lane to the blocks near Lindbergh Boulevard.
While you wait, close the shutoff valve behind a running toilet or the main valve if water is spreading. Do not run the dishwasher or washer if drains are slow. If you rent, tell your landlord or property manager right away, because they often need to place the call.
Hazelwood has a large renter population and a lot of working commercial land, and both shape the problems we see. This page starts with the problem, then covers who pays, who calls and what the work involves.
Plumbing problems that cannot wait in Hazelwood
Dispatch runs around the clock, so you do not have to wait for morning to reach a person. These four calls are the ones that most often justify a night visit.
Overflowing toilet
When the bowl keeps rising, shut the valve behind it. If the water is not clean, keep people away and call.
Clogged main drain
Several slow fixtures at once, or a gurgle in the tub when the toilet flushes, point to the main line.
No hot water
A tripped limiter, a failed element or a leaking tank are different problems. Describe what you see to the dispatcher.
Water under a sink
Close the shutoff valves under the cabinet and put a bucket beneath the trap until we arrive.
Most of these start with drain cleaning or toilet repair, and a camera follows if the same fixture backs up again. If the unit is the problem, water heater repair comes first.
Renters, landlords and the city's registration program
Hazelwood runs a Rental Registration Program through City Hall at 415 Elm Grove Lane, and Code Enforcement handles building codes and permits. If you are a landlord, a registered rental that has an unresolved plumbing complaint is a problem you want to fix quickly. Call us the same day the tenant reports it.
Tenants should report a leak or a backup in writing as well as by phone, and take dated photos. For a property with several units, tell the dispatcher which unit is affected and whether neighbors share the drain, because a blockage upstairs often shows up below.
Water heater: repair or replace?
Many Hazelwood homes and rental units rely on one tank water heater. This table helps you decide before the technician arrives.
| Symptom | Often means | Usual direction |
|---|---|---|
| No hot water, tank is dry on the outside | Failed element, thermostat or igniter | Repair |
| Water pooling at the base of the tank | Corroded tank wall | Replace |
| Rust-colored hot water only | Tank interior corroding or anode spent | Inspect, often replace |
| Tank is old and repairs keep recurring | Wear throughout the unit | Replace |
A leaking tank cannot be patched, so water heater replacement is the path once the tank wall fails. Ask about the energy and venting options when you choose a new unit.
What a sewage backup visit looks like
Backups are the most urgent call we take, so we move in a set order.
Stop adding water
We confirm every tap, washer and dishwasher in the building is off.
Open the line
A cable machine at the cleanout or the nearest fixture opens the blockage.
Check the pipe
A camera shows roots, cracks and sags so we know whether it will return.
Test and advise
We run water through the lines and tell you whether jetting, repair or monitoring is next.
Before we arrive: what to do at a rental or a home
Whether you own or rent, these steps keep the situation from getting worse.
Shut off the right valve
Fixture valves sit under sinks and behind toilets. The main valve is where the water line enters the building.
Warn the floor below
In a multi-unit building, tell the neighbors underneath so they can move things away from the ceiling.
Reach the landlord
Message the property manager now so approval does not slow the repair once the plumber is on site.
Photograph and wait
Take a few dated pictures, then keep the area clear for the crew.
Where we cover in Hazelwood
Hazelwood's ZIP code is 63042, and the city lies north of Lambert airport along I-270, I-170, Lindbergh Boulevard and Highway 370. Our crews approach from Maryland Heights, which keeps one dispatch zone for the whole area.

The Ford site, Aviator Business Park and commercial calls
The Ford plant closed in 2006 after 58 years and about 1,400 employees, and the site is being redeveloped as Aviator Business Park. Newer commercial space in and near Hazelwood means offices, warehouses and light industrial units with restrooms and break rooms. That is where commercial plumbing calls come from, and they are often scheduled outside business hours.
Hazelwood is also close to Earth City, 63045, which we serve from the same zone. Nearby Bridgeton and St. Charles are on the dispatch map too.
Codes and rules to check in Hazelwood
Hazelwood sets its own permit rules, and the International Plumbing Code (IPC) is a model that the city may adopt with its own changes. Ask the city which jobs need a permit, since a like-for-like repair and a replacement are often treated differently.
Water heaters made to the ANSI Z21.10.1 standard need a relief valve and a drain pan where a leak could reach finished floors. Ask the plumber to show you where the discharge pipe ends before the job is closed out.
