Primary pumps + battery & water-powered backups. Complete basement flood protection for Riverdale homes.
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.
Complete system from pit excavation to discharge piping, check valve, and dedicated electrical circuit.
Full evaluation of existing pit and discharge before installing the new pump.
Runs on municipal water pressure during power outages — no battery required.
Automatic activation with marine-grade batteries and alarms for power outages or pump failure.
Float switches, check valves, debris removal, and full system testing.
Installed during rough-in phase for optimal integration and lowest long-term cost.
Suitable for low-risk, unfinished basements with reliable power.
Ideal for finished basements and areas with frequent outages.
Excellent for municipal water homes wanting maintenance-free backup.
Maximum redundancy for high-value finished basements and vacation homes.
"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."
— David W., Riverdale homeowner
"They quoted me for a pump replacement and explained that my existing pit was actually too small... The honest assessment won me over."
— Linda K., Riverdale homeowner
We measure pit fill rate and select capacity well above peak inflow for your specific Riverdale basement.
For finished basements or valuable contents, backup capability is almost always worth the investment.
Most residential sump pumps in Riverdale last 7 to 12 years. Pumps over 10 years old are on borrowed time.
Standard pumps do not. Battery or water-powered backups are essential during storms.
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.
Protect your Riverdale basement before the next storm. Get an honest evaluation of your current setup and the right configuration for your risk level.
