Pumps Guide

Submersible sump pumps last 7-10 years on average. Pedestal pumps can last 15-25 years since the motor stays above water. Replacement should be proactive — don't wait for failure during a storm. Mark the installation date on the pump.

If your area experiences power outages during storms (when sump pumps are needed most), a battery backup is essential. Even a brief power loss during heavy rain can lead to flooding. Battery backup systems provide 5-12 hours of pumping depending on inflow rate.

1/3 HP handles most residential applications with moderate water inflow. 1/2 HP is recommended for homes with frequent or heavy water intrusion. 3/4 to 1 HP is for high water table areas or large homes. Oversizing is better than undersizing.

Frequent cycling is usually caused by a failed check valve (water flows back into the pit after each cycle), an undersized pit, a high water table, or a stuck float switch. Check the check valve first — it's the most common cause and cheapest fix.

In most jurisdictions, discharging sump pump water into the sanitary sewer is illegal because it can overwhelm the treatment plant during storms. Discharge must go to the yard surface, a storm drain, or a dry well — check your local building code.

A hot water recirculation pump circulates water through your hot water pipes so you get instant hot water at every faucet without waiting. It reduces water waste (saves 10,000-15,000 gallons/year for a typical home) but adds a small amount to your energy bill.
