A sump pump isn't glamorous. But when water starts creeping in, it's the single most important piece of equipment standing between your basement and thousands of dollars in damage. Let's make sure yours is up to the job.
Our Sump Pump Services in Longmont, CO
From a quick repair to a complete system upgrade, EP Plumbing, Heating & Air handles every part of sump pump care. Below is a closer look at what we do and why it matters for your home.
Sump Pump Installation
A good installation starts long before the pump goes in. We evaluate your basement's drainage needs, look at how groundwater moves around your foundation, and figure out the right pump size for your space. Undersized pumps burn out fast. Oversized ones cycle too often. We get it right the first time.
Our sump pump installation in Longmont covers the full job:
- Installing or upgrading the sump pit in the lowest point of your basement
- Routing the discharge line so water flows safely away from the foundation
- Fitting a check valve to keep water from flowing back into the pit
- Calibrating the float switch so the pump turns on and off at the right levels
- Testing the whole system before we leave
- Making sure everything meets local plumbing code
We handle sump pump installation in basements across Longmont CO, from finished basements in Prospect New Town to older homes near Downtown Longmont, plus new construction and crawl spaces where they make sense. The goal is always the same: protect your foundation from groundwater intrusion.

Sump Pump Repair
When a pump acts up, you usually notice at the worst possible time. Common problems we fix include:
- A pump that won't turn on
- A sump pump running constantly or cycling too often
- Float switch failure
- Motor burnout
- Clogged or frozen discharge lines
- Worn check valves
- Electrical faults and excessive vibration
We diagnose the actual cause instead of guessing, then give you honest options. If a sump pump repair makes sense, we fix it. If not, we'll tell you straight.

Sump Pump Replacement
Every pump wears out eventually. Most last around 7 to 10 years, and older units start to struggle right when the water table rises. If your pump keeps failing, runs nonstop, or can't keep up during snowmelt, a sump pump replacement in Longmont is often smarter than another repair.
We help you compare submersible and pedestal units, match capacity to your needs, and install a system that'll keep working for years.
Sump Pump Maintenance and Inspections
Most basement floods trace back to a pump nobody tested. Routine maintenance is cheap insurance. During an inspection we clean the sump pit, test the float switch, check the discharge line, confirm the check valve seals, and run the pump under load. Regular service extends equipment life, improves reliability, and helps you avoid emergency repairs down the road.
Battery Backup Sump Pump Systems
Storms and power outages tend to arrive together. A battery backup sump pump in Longmont keeps your basement protected even when the electricity goes out or your primary pump fails.
With a primary and backup pump setup, the system switches over automatically the moment the main pump stops. We handle battery backup sump pump installation from start to finish, then show you how to test it so you're never caught off guard.
