## Basement & Crawlspace Flood Defense

In Western Washington and the Puget Sound basin, seasonal rainfall and high winter water tables place immense hydrostatic pressure on residential foundations, basements, and crawlspaces. A reliable sump pump system is the primary line of defense against structural mold, rot, and flooded living spaces.

### Sump Pump Solutions Installed by AYSP

#### 1. Primary Cast-Iron Submersible Sump Pumps
* Engineered with heavy-duty cast iron housings for superior heat dissipation and continuous motor operation.
* Non-clogging vortex impellers capable of discharging up to 4,000+ GPH of groundwater.
* Solid-state or mechanical vertical float switches designed to eliminate switch hang-ups.

#### 2. Dual Battery Backup Sump Pump Systems
* **The Problem:** Severe Pacific Northwest windstorms often knock out neighborhood electrical power exactly when rainfall is at its peak.
* **The Solution:** A dedicated secondary 12V DC pump paired with a maintenance-free marine deep-cycle battery and smart charging controller.
* **Redundancy:** If the primary pump fails or grid power goes out, the backup pump automatically activates, providing up to 48–72 hours of continuous groundwater pumping.

#### 3. Sump Basin Maintenance & Check Valve Upgrades
* Installation of silent, anti-water-hammer spring-loaded check valves to eliminate pipe thumping.
* Basin sediment removal and discharge line freeze-protection checks.
