Pump runs constantly but pit stays full
We test the check valve and float switch with a pressure testing gauge. Most of the time, a failed check valve lets water drain back into the pit. We replace the valve and verify the pump holds pressure.

About this service
Sump Pump Leak Detection in Houston: What It Is and Why It Matters
Sump Pump Leak Detection in Houston is a diagnostic service that locates water escaping from your sump pump system, its discharge line, check valve, or the pit itself. We use acoustic listening devices, thermal imaging cameras, and moisture meters to trace hidden leaks without tearing up your floor. The work covers the pump housing, float switch, PVC pipe fittings, and the point where the discharge line exits your foundation. Most jobs take two to four hours from arrival to repair.
Houston's flat terrain and clay-heavy soil push groundwater toward foundations after every heavy rain. When a sump pump leaks, that water has nowhere to go but into your basement, crawlspace, or slab perimeter. We see this most often in older Spring Branch and Oak Forest homes where original cast-iron drains have corroded. If your pump cycles every few minutes or your water bill jumped $80 last month, a hidden sump pump leak is the likely culprit.

What's included
What Our Sump Pump Leak Detection Service Includes
Every sump pump leak detection visit includes a full diagnostic, leak isolation, and a repair plan with upfront pricing. We do not charge extra for the inspection if you approve the repair. Here is what you get.
✓
Full System Inspection
We inspect the pump housing, float switch, check valve, discharge line, and pit walls. We use a moisture meter and thermal imaging camera to find hidden moisture. The inspection takes 30 to 45 minutes and covers every component that can leak.
✓
Electronic Leak Isolation
We use acoustic listening devices and a pressure testing gauge to isolate the leak. If the discharge line holds pressure, the leak is in the pump or valve. If it drops, we trace the pipe with a pipe inspection camera to find the crack.
✓
Same-Day Repair
We stock check valves, PVC pipe fittings, Teflon tape, and replacement pumps on every truck. That means we fix 9 out of 10 sump pump leaks on the first visit. If we need a specialty part, we tell you the cost and timeline before ordering.
✓
Pump Cycling Test
After the repair, we fill the pit with water and cycle the pump three times. We verify the float switch triggers correctly, the check valve holds, and the discharge line moves water away from your foundation. You see the pump work before we leave.
✓
Written Leak Report
You get a written summary of what failed, what we fixed, and what to watch for. If you need to file an insurance claim, the report includes photos and part numbers. We email it to you before we pack up.
How it works
Our Sump Pump Leak Detection Process
01
Phone Triage
When you call, we ask three questions: how often the pump runs, whether the pit stays full, and if you see water outside the discharge line. That tells us whether you have a check valve failure, a cracked discharge pipe, or a failed float switch. We schedule a same-day visit for most Houston addresses.
02
On-Site Inspection
A licensed technician arrives with an acoustic listening device and thermal imaging camera. We inspect the pump housing, float, check valve, and every PVC pipe fitting from the pit to the exterior discharge point. The visual and electronic inspection takes 30 to 45 minutes.
03
Leak Isolation
We use a pressure testing gauge and hydrostatic test pump to isolate the leak. If the discharge line holds pressure, the leak is in the pump or check valve. If it drops, we trace the pipe with a pipe inspection camera to find the crack or failed joint. This step takes 20 to 40 minutes.
04
Repair and Replacement
We repair or replace the failed component on the spot. That means a new check valve, a section of PVC pipe, or a pump replacement if the motor is shot. We use Teflon tape and pipe sealant on every threaded joint, and we solder copper connections where required. Most repairs finish within two hours.
05
Testing and Verification
Before we leave, we fill the pit with water and cycle the pump three times. We verify the float switch triggers correctly, the check valve holds, and the discharge line moves water away from your foundation. You get a written summary of what failed and what we fixed.
Tools & methods
Tools and Methods We Use for Sump Pump Leak Detection
Purpose-built equipment, used by trained technicians — so the job is done accurately the first time.
Acoustic Listening Device
Amplifies the sound of water escaping under pressure. We use it to pinpoint leaks in discharge lines and check valves within inches, even through concrete.
Thermal Imaging Camera (FLIR)
Shows temperature differences caused by leaking water. We use FLIR cameras to spot hidden moisture behind walls and under floors without demolition.
Pressure Testing Gauge
Isolates the sump pump discharge line and pressurizes it. If the gauge drops, we know the line leaks and can trace it with a pipe inspection camera.
Pipe Inspection Camera (RIDGID)
Goes inside discharge lines and drain pipes to find cracks, root intrusion, and failed joints. We use RIDGID cameras because they fit tight bends in PVC pipe.
Moisture Meter (General Tools)
Measures moisture content in walls, floors, and pit walls. We use it to confirm whether a leak is active or has already dried.
Tracer Gas Detector (Sewerin)
Finds leaks in buried discharge lines by injecting a safe tracer gas and detecting where it escapes. This avoids digging up your yard.
Hydrostatic Test Pump
Fills the sump pit and discharge line with water under controlled pressure. We use it to verify repairs hold before we leave your property.
Real results
Before and after.
Failed Check Valve in Spring Branch
Before
A homeowner in Spring Branch called us because their sump pump ran every 10 minutes and their water bill had climbed $90 in one month. The pump was only two years old, so they thought it was defective. We found a failed check valve that let water drain back into the pit after every cycle.
After
We replaced the check valve with a new brass unit and tested the line with a hydrostatic test pump. The pump now cycles twice a day instead of every 10 minutes. The homeowner's next water bill dropped by $85, and the pump motor is no longer overheating.
Cracked Discharge Line in The Heights
Before
A property manager in The Heights had two rental units with water seeping from the sump pit onto the basement floor. The tenants complained of musty smells. We used a thermal imaging camera to find the leak and a pipe inspection camera to confirm a cracked PVC discharge line at the foundation exit point.
After
We replaced the cracked section of PVC pipe with new Schedule 40 PVC and flexible couplings to absorb soil movement. We sealed the pit walls with epoxy pipe repair and dried the area. Both units passed a 15-minute pressure test, and the musty smell was gone within 48 hours.
Clogged Discharge Line in Memorial
Before
A Memorial homeowner called at 11 p.m. during a storm because their basement was flooding. The sump pump was running but water was not moving. We found a clogged discharge line blocked by root intrusion from a nearby oak tree. The pump was pushing water against the blockage and overflowing the pit.
After
We cleared the roots with a pipe inspection camera and cutting tool, then replaced the damaged section of PVC pipe. We installed a new check valve and tested the system three times. The pump moved water normally, and the basement was dry by 1 a.m. The repair cost $380.
Problems we solve
Sump Pump Problems We Solve for Houston Homeowners
A leaking sump pump shows up in different ways. Here are the most common problems we fix in Houston and what happens if you ignore them.
Ask a pro →↗
Water pooling around the pit or basement floor
We use a moisture meter and thermal imaging camera to trace the water source. If the pit itself is cracked, we seal it with epoxy pipe repair. If the discharge line leaks, we replace the failed section of PVC pipe.
Musty smell in basement or crawlspace
We find the leak with an acoustic listening device, repair it, and dry the pit area. We also check the discharge line for root intrusion, which is common in older Houston neighborhoods with mature trees.
High water bill with no visible leak
We isolate the sump system from your main water line with a hydrostatic test pump. If the gauge drops, we know the leak is in the sump system and trace it with a pipe inspection camera.
Transparent pricing
Sump Pump Leak Detection Pricing in Houston
$89 diagnostic (waived with repair) - $180 to $450 for most repairs
We charge $89 for the diagnostic, and we waive that fee when you approve the repair. Most sump pump leak repairs in Houston run $180 to $450 total in 2026. The price depends on what failed, how hard it is to reach, and whether we need to replace the pump. We give you the full price before we start, so you never get a surprise bill.
Fixing a sump pump leak early costs $180 to $450. Ignoring it can lead to a flooded basement, mold remediation at $2,500 to $6,000, and foundation repairs that start at $8,000. The math is simple.
01Leak Location
A check valve leak at the pump is easy to reach and costs $180 to $250 to fix. A cracked discharge line under a concrete slab takes longer to trace and repair, pushing the cost to $350 to $450.
02Parts Needed
A new check valve costs $45 to $85 installed. A replacement sump pump runs $250 to $600 depending on horsepower and brand. We stock the most common parts on every truck.
03Access Difficulty
If your sump pit is in a finished basement with limited access, we may need to move furniture or cut a small access panel. That adds $50 to $150 to the job.
04Emergency Timing
Calls between 10 p.m. and 6 a.m. or on major holidays add a $75 after-hours fee. We still answer the phone 24/7 and dispatch a technician within 90 minutes.

“We manage six rental properties in The Heights, and two had sump pump leaks after the May storms. Their technician came out on a Saturday, found cracked PVC discharge lines on both, and repaired them before the next rain. The tenants stopped calling about musty smells. Worth every penny.”

“I called at 11 p.m. when my basement started flooding during a storm. They had a technician at my house in 75 minutes. He found a broken float switch and a clogged discharge line. By 1 a.m. the pump was cycling correctly and the water was gone. That is real 24/7 service.”

✓ VerifiedMost sump pump leak detection jobs in Houston cost $89 for the diagnostic, which we waive if you approve the repair. Total repair costs run $180 to $450 depending on whether we replace a check valve, a section of PVC pipe, or the pump itself. Emergency calls after 10 p.m. add a $75 after-hours fee.
The most common cause is a failed check valve that lets water drain back into the pit, causing the pump to cycle constantly and overflow. Houston's clay soil also shifts with wet and dry cycles, cracking PVC discharge lines at the foundation exit point. A worn float switch or a corroded impeller can also cause leaks.
