About Product Overview

The Little Giant SUB UTIL PUMP 1/15HP 500 is built for jobs that need constant manual control rather than automatic float-switch operation - think draining a flooded basement floor, pumping down a window well, clearing a low spot in the yard, or keeping water out of a boat bilge. At 1/15 HP it moves up to 500 GPH and pushes water up to 17.3 feet of head through a 1/2" discharge, and being self-priming means it gets to work fast even in shallow, low-water conditions.

The aluminum housing resists corrosion, so it holds up to repeated exposure to standing water without breaking down over time. It's a switchless design, meaning you control on/off manually - useful when you don't want a pump kicking on and off automatically. Runs on standard 115V AC power and carries UL compliance for added confidence, backed by a 1-year warranty from Little Giant.

Go ahead. Check.

You're going to open the other tab. Everybody does. We'd rather say so than pretend otherwise — so open it. We'll wait.

When you're over there, check four things 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 Little Giant. 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

We're not always the cheapest.

Sometimes you'll find it for less. Sometimes you'll find it for more. On a lot of brands the number is identical everywhere it's sold legitimately — the manufacturer sets a minimum advertised price and every authorized dealer holds it. When a price sits well under that, it's worth asking why before it's worth celebrating.

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.
