Signs Your Sump Pump Needs Repair
Most sump pump failures don’t announce themselves loudly. They show up as small changes — a different sound, a pump that won’t stop, a basement that feels damper than usual. These are the signals that mean something is wrong:
- The pump won’t turn on at all. You pour water into the pit and nothing happens. This usually means the float switch has failed, the motor has burned out, or the pump has lost power at the outlet. Each cause has a different repair, and a quick diagnosis separates a $100 float switch fix from a $400 motor replacement.
- The pump runs continuously without stopping. If the pump runs for hours without cycling off, the float switch may be stuck in the ‘on’ position, the discharge line may be blocked so water recirculates, or the groundwater level is genuinely high enough to overwhelm the pump’s capacity. In Aurora’s east side neighborhoods during spring snowmelt, the third scenario is more common than most homeowners expect.
- Water is in the basement despite the pump running. If the pump is clearly operating but water is still accumulating, the discharge line may be blocked, disconnected, or frozen — diverting pumped water back into the pit instead of away from the house. In Aurora winters, discharge lines that run too close to the surface or exit near the foundation freeze regularly and create this exact problem.
- The pump cycles on and off every few minutes. Rapid cycling — turning on and off repeatedly — typically means the pit is too small for the current groundwater volume, the pump is oversized for the application, or the check valve is failing and letting water flow back in after each cycle. Left unaddressed, rapid cycling burns out the motor faster than normal use.
The pit that houses your sump pump and the line that carries water away from your home are as important as the pump itself. When either fails, even a perfectly functioning pump can’t do its job.
The discharge line carries pumped water from the pit to a point outside the home — typically a storm drain connection or a drainage area in the yard. Two problems cause most discharge line failures in Aurora:
- Frozen discharge line. Aurora’s winters bring sustained below-freezing temperatures from November through March. Discharge lines that exit near the foundation or run along the exterior wall at shallow depth freeze during cold snaps, blocking water flow. The pump runs, but water stays in the pit and eventually backs up into the basement. MileFlow inspects the discharge line path and recommends insulation solutions and rerouting where needed.
Blocked or disconnected line. Roots, sediment, or physical disconnection at a joint can stop the flow. We clear or repair the affected section, confirm flow is restored, and test the full discharge path before closing the job.
A battery backup sump pump is a secondary pump that activates automatically when the primary pump fails or when the power goes out. It runs on a charged battery rather than household current, and it’s the single most effective way to protect your basement during the scenario where your protection matters most — a storm.
MileFlow installs and services two types of backup systems:
- Battery-powered backup pump. An independent pump unit sits above the primary pump in the same pit. When water reaches its float trigger — because the main pump failed or power is out — it activates and pumps water through a separate discharge line. Battery capacity typically provides 6–10 hours of protection depending on water volume. We recommend testing the battery annually before storm season.
- Water-powered backup pump (city water pressure). Uses incoming municipal water pressure rather than electricity or battery power. No battery to maintain or replace. Works as long as city water supply is active, which it typically is during power outages. The trade-off: it uses 1 gallon of city water for every 2 gallons of sump water pumped, which increases your water bill during extended activation.
If you already have a backup system installed, MileFlow services it: battery replacement, float switch testing, activation test, and discharge line inspection. We recommend servicing backup systems every spring before the season starts.

How Tankless Water Heater Installation Works
No surprises, no mystery. Here's what happens from the first call to the final test.
Free In-Home Assessment & Sizing
A technician visits your home to measure your household's peak hot water demand: how many fixtures run simultaneously, water flow rates, and your current gas or electrical capacity.
Permit & Aurora Building Code Compliance
Most tankless installations in Aurora require a building permit, especially when gas line work or new venting is involved. We pull the permit before work starts.
Removal of Your Existing Unit
We disconnect and remove your old water heater, including draining the tank and disposing of it properly. The area is left clean before installation begins.
Installation, Venting & Utility Connections
The new unit gets mounted, connected to your gas line or electrical panel, and vented to the exterior. Tankless systems require direct venting, a specific type of sealed exhaust that prevents backdrafting.
Testing, Calibration & Walkthrough
Before we leave, we run the system through full operating conditions: hot water at multiple fixtures simultaneously, temperature stability under load, and a check for any gas or water leaks.

Frequently asked questions
A float switch repair or check valve replacement typically takes 1 to 2 hours from the time the technician arrives. Discharge line repairs run 1 to 3 hours depending on the location of the blockage or damage. Motor replacement or full pump replacement takes 2 to 4 hours. We give you a time estimate before starting so you can plan your day. Most residential sump pump repairs are completed in a single visit.
Before calling, check three things: 1) Confirm the pump is plugged in and the outlet hasn’t tripped—GFCI outlets near water sources trip easily, and a tripped outlet is the most common cause of a suddenly ‘dead’ pump. 2) Pour a bucket of water into the pit and watch whether the float rises and triggers the pump. If the motor hums but nothing pumps, the impeller may be jammed. 3) Check the discharge line exit point outside your home — if it’s blocked by ice, debris, or soil settlement, the pump may be running, but water is recirculating. If none of these resolve it, call MileFlow at (720) 601-4450. If there is water on your basement floor already, move valuables off the floor while you wait for the technician.
Repair makes sense when the pump is under 7 years old, the problem is a specific component (float switch, check valve, discharge line), and the motor is in good condition. Replacement makes more sense when the pump is 10 or more years old, the motor has burned out, the pump has required repairs twice or more in the past 12 months, or the existing pump is undersized for your property’s groundwater volume. MileFlow gives you a written assessment of both options during the inspection — we do not push replacement if a repair is the right call for your situation.
An annual inspection is the standard recommendation. In Aurora specifically, the best time to schedule it is March — before the spring snowmelt season begins in April and May, when groundwater levels typically peak. The inspection should include testing the float switch activation, checking the discharge line for winter freeze damage, cleaning debris from the pit, and testing the check valve. If your property is in a low-lying area near Tollgate Creek, Cherry Creek, or the Aurora Reservoir, or if your basement has flooded before, semi-annual checks in March and October are worth the cost.
