Signs You Need Service
Watch for these common issues indicating professional attention is needed.
What Is Behind These Problems
Mechanical Float Switch Failure
Possible causes: Float switches wear out or become hung up on debris, preventing the pump from turning on or shutting off.
What to check: Inspect basin float to see if it moves freely up and down.
When to call a plumber: When the pump won't activate despite high water levels.
Failed or Missing Check Valve
Possible causes: A missing or stuck check valve allows pumped water in the vertical discharge pipe to fall back into the pit, causing continuous cycling.
What to check: Check vertical discharge pipe for an operational inline check valve.
When to call a plumber: When the pump short-cycles every few seconds after pumping.
Clogged Impeller or Air Lock
Possible causes: Small gravel, mud, or air bubbles trapped in the pump volute prevent water from moving through discharge lines.
What to check: Look for an air-bleed weep hole drilled in the discharge pipe.
When to call a plumber: When the motor hums loudly but water level in the pit does not drop.

Denver Property & Plumbing Notes
Local conditions in Denver affect how plumbing systems operate over time.
Front Range Freeze-and-Thaw Cycles
Denver's extreme autumn and winter temperature swings place tremendous thermal stress on exposed pipes, hose bibbs, and exterior water lines. Disconnecting garden hoses early and winterizing unheated spaces is critical.
Expansive Bentonite Clay Soils
Much of the Denver metro area sits above expansive clay soils that swell when wet and contract during dry spells, shifting underground water and sewer laterals and stressing foundation pipe penetrations.
Historic Housing Stock & Service Lines
From Victorian brick homes in Capitol Hill to mid-century ranches in Park Hill, older properties frequently feature aging galvanized water supply pipes, cast iron waste lines, or active Denver Water lead service line replacements.

Denver Sump Pump Repair Questions
How long do sump pumps typically last?
Most residential submersible sump pumps have an operational lifespan of 7 to 10 years. Because they protect against catastrophic flooding, proactive replacement at 8 to 10 years is strongly recommended.
Why is my sump pump running continuously even when it isn't raining?
A continuously running pump usually has a stuck or tangled float switch, a broken check valve allowing water to fall back into the pit, or a high seasonal water table constantly feeding the basin.
Do I need a battery backup sump pump system?
Yes, absolutely. Severe storms that cause basement flooding often knock out electrical grid power. A battery backup pump ensures your basement stays dry even when grid electricity fails.
Why is my sump pump making loud thumping noises when it shuts off?
Loud thumping or clunking sounds indicate 'water hammer' caused by an old gravity check valve slamming shut. Installing a modern spring-loaded 'silent check valve' eliminates this noise completely.
How can I test my sump pump to make sure it works before a storm?
Slowly pour a 5-gallon bucket of water into the sump pit until the float rises. The pump should turn on smoothly, pump the water out within seconds, and shut off automatically.
