Well Pump Repair & Installation in St. Louis
Your well pump is what pushes water from hundreds of feet underground into your home. When it stops working, everything in your house stops too — no showers, no laundry, no flushing. At Well Drilling St. Louis, we get to St. Louis homeowners fast and get their water back on.
Pump failures in the St. Louis area tend to spike in two seasons. Summer heat and dry spells put heavy demand on wells — pumps that run harder in drought conditions wear out faster. Then again in winter, hard freezes stress pressure tanks and above-ground components. St. Louis winters can drop well below freezing. If your pump quits in January, your family can't wait three days for a technician. We prioritize emergency calls.
We service all types of well pumps — submersible pumps, jet pumps, and booster pumps. Whether your pump needs a fast repair or a full replacement, our licensed technicians show up with the right equipment to get the job done.
We also install new pump systems for newly drilled wells and upgrade aging systems to modern constant-pressure technology.
Signs Your Well Pump Needs Repair
No Water at All
Turn on a faucet and nothing comes out. The pump may have failed, the pressure switch may be stuck, or there is an electrical issue feeding the pump. Call us — we find the cause fast.
Low or Fluctuating Pressure
Pressure drops when you run two faucets at once, or bounces throughout the day. This usually points to a failing pressure tank, a worn pump, or a waterlogged tank — a tank that has lost its air cushion and can't hold pressure.
Pump Runs Continuously
A pump that never shuts off is burning itself out. It usually means a leak somewhere in the system, a bad pressure switch, or a check valve that isn't holding. Left alone, it will fail completely.
Sputtering or Air in Lines
Air blasts from the faucet mean the pump is pulling air instead of water. That can happen when the water level in the well drops below the pump intake, when there is a crack in the drop pipe, or when the pump itself is failing.
Dirty or Sandy Water
Sand or grit in your water can mean the pump has slipped too low in the well, the well screen is torn or clogged, or the well casing itself has a crack letting sediment in. Get it checked before the pump wears out from running dirty.
High Electric Bills
A pump that clicks on and off constantly — short-cycling — draws more electricity than normal. You'll see it in your bill. A properly sized pump and pressure tank run efficiently and quietly. We fix the cycle issue and lower your energy cost.
Our Well Pump Services
Submersible Pump Repair & Replacement
Submersible pumps sit hundreds of feet down inside your well — you can't see them or reach them without the right equipment. When they fail, we pull the pump from the well, diagnose the problem, and repair or replace it. A typical submersible pump lasts 8 to 15 years. Hard, mineral-rich water like what is common in the St. Louis area can shorten that lifespan if the pump is not properly sized.
Pressure Tank Replacement
Your pressure tank is a buffer between the pump and your plumbing. It stores pressurized water so the pump does not kick on every time you turn on a faucet. When the tank goes waterlogged — meaning the air bladder inside has failed — the pump short-cycles and wears out early. You get your water back with steady, even pressure and a pump that lasts.
Constant Pressure Systems
A constant pressure system uses a variable frequency drive — a controller that adjusts your pump speed in real time. Instead of the pump switching on at 40 PSI and off at 60 PSI, it ramps up and down to hold steady pressure no matter how many showers or faucets are running. You get smooth, consistent pressure like city water, but from your own well.
Pressure Switch & Controls
Not every pump problem is the pump. Pressure switches, control boxes, and wiring fail too — and those repairs are faster and less expensive than pulling the pump. We check the electrical side first. If that is the issue, you get your water back the same day.
Well Pump Repair Cost in St. Louis
Pump repair costs in the St. Louis area vary by what failed. A pressure switch or control box fix costs far less than pulling and replacing a submersible pump from 150 feet down. We figure out the root cause first, then give you a clear written estimate with exact costs before we start any work.

Frequently Asked Questions
How long do well pumps last?
Submersible pumps typically last 8 to 15 years. Hard, mineral-rich water — common in the St. Louis area due to the limestone geology — can shorten that if the pump was not sized correctly. Usage patterns matter too. A pump running constantly during a summer drought wears faster than one running normally.
Can you repair my pump the same day?
We prioritize emergency calls. A family without water can't wait. Simple repairs — pressure switches, control boxes, wiring — are often done the same day. Pulling and replacing a submersible pump takes more time but we typically complete those jobs within 24 to 48 hours.
Should I repair or replace my well pump?
If the pump is under 8 years old and the problem is electrical or mechanical, repair usually makes sense. If it is 10 or more years old, has failed before, or your water is hard and minerally — which accelerates pump wear — replacement gives you better long-term value and a pump you can count on.
What is a constant pressure system?
A constant pressure system uses a variable frequency drive — a controller that ramps your pump up and down to hold steady pressure in real time. No more pressure drops when someone showers while the dishwasher runs. You get smooth, consistent pressure at every fixture.
