What a sump pump does, and what keeps it working
A sump pump sits in a pit that collects water, and a float switch starts the motor as the level rises. The pump sends the water through a discharge pipe to a point away from the house.
Power and the discharge pipe decide whether it works in a storm. A power cut stops it unless it has a battery backup, and a blocked discharge pipe keeps the water from leaving.
Texas sump pump install: our estimate
Installing a sump pump comes to $675 to $2,100 installed on our model, an estimate and not a quote. The model rests on 3 national published ranges and Texas plumber pay. No permit is added, because permit rules vary by city.
| Item | Figure | What it is |
|---|---|---|
| Estimated range, not a quote | $675 to $2,100 installed | Built from 3 national published ranges, adjusted by the Texas plumber wage ratio (0.84). Four Texas plumbing companies publish a price we could count on their own websites; where five or more price the same job, the range is the middle half of their prices, and where two to four do, the estimate is widened to take them in. Coupons, specials and figures a page gives as an average are not counted. Basis: no state company sample (no counted Texas company price for this job), national estimate only. |
| Plumber wage, Texas mean | $29.22 an hour | Texas plumbers' average hourly pay in the BLS May 2025 survey; not what a company charges. |

Repair the pump, or replace it?
A pump that fails the bucket test can be a stuck float, a clogged intake or a dead motor, and a company can tell which in one visit. Ask what the repair costs next to a new pump before agreeing to either.
- The float is stuck or tangled and the motor runs when freed.
- Debris is clogging the intake or the pit.
- The motor won't start with power and a free float.
- The pump keeps failing the bucket test after a repair.

Where the pumped water goes
The state plumbing rules on this page don't say where a sump pump may discharge, so ask your city's public works office before the pipe is routed.
Sump trouble that can't wait
- Water is entering faster than the pump removes it.
- Standing water has reached an outlet or the electrical panel.
- A pump that runs more often than it used to but keeps the pit down.
- A noisy motor in a dry pit.
Check the pump before the next storm
- Pour a bucket of water into the pit and watch the pump start, empty the pit and shut off.
- Look at the discharge pipe outside and confirm it's open and carries water away from the house.
- Check that the cord reaches a working outlet and that the pit has no debris in it.
- Ask a company whether a battery backup fits your pump.
Will your city want a permit for a sump pump?
Texas has no state plumbing permit. Waco's undated inspection schedule lists $10 for each sump pump, grinder pump or lift station, and your own city's permit office can tell you whether it permits one and what it charges.
Before any work starts, ask for the license number of the company's Responsible Master Plumber and search it on TSBPE's public license search.

How do I test my sump pump?
Pour a bucket of water into the pit and watch it empty. Water in the pit should raise the float, start the motor and empty the pit before the pump shuts off. If it doesn't, check the outlet and the float before you call.
Can my sump pump drain into the street?
Ask your city's public works office first. Ask the city's public works office before the discharge pipe is pointed at a street or a storm drain.
