About Product Overview

Cast iron housing and a submersible design make this Zoeller sump pump built for the wet, unglamorous work of keeping a basement or crawlspace dry. It draws water in through a bottom suction intake and pushes out up to 80 gallons per hour, with enough lift to handle up to 20 feet of head - plenty for most residential sump pits.

The vertical float switch turns the pump on and off automatically as water rises and falls, so it runs unattended once it's installed. A 1.5-inch discharge outlet fits standard sump pump piping, and the 9-foot cord gives some flexibility in pit placement without needing an extension cord run to the panel.

Backed by a 3-year warranty and CSA compliance, it's a solid pick for homeowners dealing with regular groundwater intrusion or seasonal flooding risk who want a pump they can install once and trust to do its job.

Go ahead. Check.

You're going to price-check us against Amazon, Home Depot, and Lowe's. Everybody does. Good — open all three tabs. We'll wait. Then look hard at what you're actually being handed over there.

On Amazon, start with these four questions before you click buy.

01

Who's actually selling it

The brand name is on the listing. A different company is in the seller field. Those aren't the same thing, and the second one is who you're buying from.

02

Whether the warranty survives

Most manufacturers only honor a warranty when the unit came through an authorized dealer. We're authorized for Zoeller. A third-party marketplace seller usually isn't.

03

Where the box came from

Gray-market stock, returns repackaged as new, and outright fakes move through marketplaces constantly. It all looks identical in the photo. It stops looking identical when it fails.

04

Who you call when it breaks

Ours is a phone number with a person behind it who has held this product. M–F, 6 AM – 5 PM Pacific. (866) 469-8556

The big boxes don't care if your hardware store survives.

Amazon, Home Depot, and Lowe's are built to pull every hardware dollar out of your town. When the local shop can't keep the lights on, the counter where somebody actually knew which part you needed goes with it. We're built the other way: real brands so you're never stuck on a marketplace, and a straight answer to buy it down the street when that's the better call. Support independent hardware — it doesn't restock itself.

Why we tell you to shop local

Shop Local · Support Independent

Every order helps keep your local hardware store on the corner.

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.
