When your basement’s last line of defense fails, MT Dunn Plumbing is the team Hillsboro homeowners call to get it running again.
A structured diagnostic process ensures we fix the actual problem, not just reset the symptoms.
Technicians ask what you’ve noticed, whether the pump isn’t turning on, running constantly, cycling oddly, or making unusual noise, to narrow down likely causes before inspection.
The sump pit is checked for debris, sediment buildup, water level, and visible damage to the pump housing or power cord.
Technicians manually raise the float to confirm it triggers the pump correctly, since a stuck or misaligned float is one of the most common failure points.
Power supply, outlet function, and any tripped GFCI breakers are tested to rule out electrical causes before assuming a mechanical failure.
The check valve is examined to confirm it’s preventing water from flowing back into the pit after each pump cycle.
Technicians check the discharge pipe for clogs, ice blockages, or kinks that could be restricting water flow away from the home.
If the pump powers on but doesn’t move water effectively, the motor and impeller are inspected for wear, jamming, or burnout.
For homes with backup units, battery charge, connections, and automatic switchover function are tested to confirm reliability during outages.
Based on findings, technicians replace the failed component, whether that’s a float switch, check valve, power cord, or full pump unit.
Once repaired, the system is tested through multiple pump cycles under simulated water conditions to confirm consistent, reliable operation.
Most sump pump repairs are completed in under an hour; full pump replacements typically take one to two hours depending on pit access and piping configuration.
Don’t wait for a flooded basement to find out your pump has failed. Call us if you notice:
These are the issues our technicians encounter most often in Hillsboro homes.
From what we’ve seen, the answer depends on your sump pump’s age, condition, and repair history. At MT Dunn Plumbing, we help homeowners make the most cost-effective decision based on the pump’s remaining lifespan, not just the immediate repair.
A sump pump is one of the most important safeguards against basement flooding, but like any mechanical equipment, it won’t last forever. While some problems can be repaired quickly and affordably, older pumps often become less reliable as internal components wear out. Choosing between repair and replacement should always be based on long-term dependability rather than the lowest upfront cost.
We’ve repaired many sump pumps that were less than five years old where the issue was limited to a float switch, check valve, or another replaceable component. In these situations, a targeted repair is usually the most practical and economical solution, allowing the existing pump to continue operating reliably for years.
Once a pump reaches seven to ten years of age or has required multiple repairs, the likelihood of another failure increases, often during the heavy rainstorms when dependable operation matters most.
The cost of replacing an aging sump pump is often far less than the expense of repairing water damage caused by a flooded basement. We think of it as investing in dependable flood protection, especially when a new system is paired with a battery backup to keep operating during power outages.
If your sump pump is older, has needed repeated repairs, or shows signs of declining performance, it’s worth having it professionally evaluated. We’d rather recommend replacement before a major storm than see you deal with preventable flooding after the system fails.
Sump pumps handle groundwater, but they can also collect debris that restricts water flow, damages internal components, or causes complete pump failure. Identifying the source of the clog helps determine the most effective repair.
Type of Debris
Dirt and Sediment
Sand and Gravel
Small Stones

Miscellaneous Household Debris
How It Affects the Sump Pump
Settles in the sump pit and can clog the pump intake or wear down internal components.
Enters through drainage systems and may jam the impeller or reduce pumping efficiency.
Can block the intake screen or damage the impeller during operation.
Forms thick deposits that restrict water flow and make the pump work harder.
Often enter uncovered sump pits and can block the intake or discharge line.
May invade damaged drain tiles or discharge piping, restricting water movement.
Pieces of concrete, drywall, wood, or insulation can clog the pump after renovation work.
Corrosion from aging plumbing components can accumulate and interfere with pump operation.
Moist conditions can encourage biological buildup that partially blocks water flow.
Plastic fragments, paper, or other foreign objects accidentally entering the pit can obstruct the pump.
Keeping the sump pit clean and scheduling routine inspections helps prevent debris buildup, allowing your sump pump to operate efficiently when heavy rainfall or rising groundwater threatens your home.
