Sump Pump Installation Union

Primary pumps + battery & water-powered backups. Complete basement flood protection for Union homes.

SCROLL TO LEARN MORE

Picture the scenario. A heavy storm rolls through. Power goes out. Your sump pump stops running. Water keeps coming into the pit. The basement floor starts collecting water.

Or maybe the pump has been running fine for ten years and suddenly fails with no warning. Or a piece of debris jams the float switch.

Three different failure modes. Three different ways a basement floods. A single sump pump is a single point of failure. The right installation accounts for what happens when the primary fails.

Customer Reviews From Union

"Alliance installed a primary with both battery and water-powered backups. Last fall we had a major storm with a six-hour power outage. Basement stayed completely dry."

— Linda K., Union homeowner

Frequently Asked Questions

How do I know what size sump pump I need?

We measure pit fill rate and select capacity well above peak inflow for your specific Union basement.

Do I really need a backup sump pump?

For finished basements or valuable contents, backup capability is almost always worth the investment.

How often should a sump pump be replaced?

Most residential sump pumps in Union last 7 to 12 years. Pumps over 10 years old are on borrowed time.

Do sump pumps work during power outages?

Standard pumps do not. Battery or water-powered backups are essential during storms.

Why Sump Pumps Fail at the Worst Possible Moment

Most basement flooding happens during heavy storms that cause both water entry and power outages. A standard pump stops when power goes out. Redundancy decouples you from these failure modes.

Schedule a Sump Pump Assessment

Protect your Union basement before the next storm. Get an honest evaluation of your current setup and the right configuration for your risk level.
