About Product Overview

Star Water Systems built this 1 HP sprinkler pump for homeowners who need to pull water from a well, pond, or lake and push it through an irrigation system with enough force to reach every zone. The cast iron housing stands up to the corrosion that kills lesser pumps, and the self-priming design means you're not fussing with manual priming every time you switch it on. A pressure switch handles the on/off cycling automatically, so the pump only runs when your system calls for water.

With a 1-1/2 inch discharge and the ability to push water up to 25 feet of head, it's sized for typical residential lawn and garden sprinkler setups. It runs on either 115 or 230 volts, giving you flexibility on wiring, and it's CSA and UL listed for safety compliance. Backed by a 2-year limited parts and labor warranty and assembled in the USA.

Price check

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 Star Water Systems. 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.

Ask our counter. Or theirs.

Most hardware stores can do more than you think. If we can't help you, the folks down the street probably can — just ask at the counter.

Their Counter
Try local first · we'll wait

The stores we send you to are local and independently run — often for generations, the kind of place where someone behind the counter knows the regulars. We don't own them. We just think they deserve the foot traffic. They can put most of what we sell on their next truck. Ask there before you check out here.

About our directory. National Hardware Group is an independent retailer and directory. The local stores we list and link to are separately owned and operated — we have no ownership stake in any of them, and most pay us nothing to be included. That includes plenty of stores flying a familiar banner that people don't realize are locally owned and run, not operated by a corporation. Store owners can choose to upgrade their listing for an enhanced presence or pickup features, but the base directory is free, and inclusion is never a paid endorsement.
