Plumbing โ FAQ
What size sump pump do I need for a typical basement?
Most basements require 1/3 to 1/2 HP pumps moving 3,000-4,500 GPH. Our Westinghouse 1/2 HP top pick handles severe flooding, while the 1/3 HP model suits moderate water tables. Calculate your needs based on pit diameter and local water table height.
Can I use a pool pump or aquarium pump as a budget sump pump?
Only for very light duty. Pool pumps like our 1,200 GPH pick handle window wells and minor seepage but lack the power and durability for active basement flooding. Aquarium pumps suit tiny crawl spaces but will burn out quickly under continuous flood conditions.
What's the difference between a vertical float and tethered float switch?
Vertical floats move straight up and down in narrow pits, cycling faster with less hang-up risk. Tethered floats swing in wider arcs, need more pit space, but handle larger water volumes. For most basements, vertical floats offer better reliability.
How long do budget sump pumps typically last?
Budget cast iron pumps last 5-7 years with proper maintenance. Thermoplastic models average 3-5 years. Our Westinghouse pick features cast iron construction typically found in $200+ pumps. Annual cleaning and testing extend lifespan significantly.
What is a piggyback float switch and when do I need one?
Piggyback switches plug into the wall, then your pump plugs into the switch. This lets you replace a failed switch without rewiring. Buy the Little Giant RFSN-9 when your pump motor runs but the original float switch stops cycling properly.
How often should I test my sump pump?
Test monthly by pouring water into the pit until the float activates. Clean the intake screen quarterly. Before heavy rain seasons, run a full cycle test and verify discharge line clearance. This 10-minute routine prevents 90% of pump failures.
