Gateway Supply Co: Where to Find Plumbing Parts and Tools in South Carolina

What Gateway Supply Co offers and where to find them

Gateway Supply Co is a plumbing supply distributor with locations across South Carolina that stocks pipes, fittings, fixtures, and tools for both professional plumbers and homeowners tackling their own repairs. They carry brand-name products like Kohler, Moen, and PEX tubing alongside contractor-grade equipment. The company operates multiple locations throughout the state, making it a regional option when you need parts the same day rather than waiting for mail delivery.

Unlike big-box retailers that stock a general selection, Gateway Supply focuses on plumbing-specific inventory. That means deeper stock of specialty items—water heaters, rough-in valves, sump pump components, and professional-grade tools—that you might not find at a hardware store. Staff at each location typically have plumbing knowledge and can help you identify the right part if you bring a photo or describe the problem.

The company also serves as a wholesale distributor for licensed plumbers, which means they may offer contractor pricing on bulk orders or frequent purchases. If you're a homeowner buying one or two items, you'll pay retail prices; if you're a professional, ask about account options.

• The store carries brand-name products and specialty items that general hardware stores often do not stock.

How to find your nearest Gateway Supply location

Gateway Supply operates stores in several South Carolina cities, but the exact number and addresses change over time. The most direct way to find a current location is to search online for "Gateway Supply Co South Carolina" or call their main number to confirm which store is closest to you and whether they have the specific item you need in stock.

When you call ahead, have the product name or part number ready if you know it. If you don't, describe what you're fixing—for example, "I need a replacement cartridge for a Moen kitchen faucet"—and staff can tell you whether they have it and what it costs. This saves a trip if the part is out of stock.

What to bring when you shop for replacement parts

If you're replacing an existing fixture or component, bring the old part with you if possible. Plumbing parts come in many sizes and configurations, and showing staff the actual item you're replacing eliminates guesswork. If you can't remove it, take a clear photo from multiple angles and bring your phone.

For faucets, note the brand and model number if it's visible on the base or handle. For pipes and fittings, measure the diameter and note whether the connection is threaded or soldered. For water heater parts, know whether your tank is gas or electric and its approximate age. These details help staff find the exact match rather than a close approximation that won't fit.

Bring your measurements in both inches and millimeters if you're unsure which standard applies—plumbing uses both, and a quarter-inch difference can mean the part won't seal properly.

Pricing and payment options

Gateway Supply prices vary by product and location, but generally fall between online retailers and big-box stores for common items. Specialty or hard-to-find parts may cost more than you'd pay online, but you avoid shipping delays and return hassles. The trade-off is convenience: you get the part today instead of waiting three to five business days.

Most locations accept cash, card, and checks. Some may offer contractor accounts with net-30 or net-60 payment terms if you're a licensed plumber or run a plumbing business. Ask at the counter whether account options are available in your area.

When to call ahead versus walking in

Call ahead if you need a specific part and want to confirm it's in stock before driving to the store. This is especially important for less common items, seasonal products, or anything you're not 100 percent sure about. A five-minute phone call saves a wasted trip.

Walk in if you're browsing for supplies, need staff advice on what to buy, or are picking up something you've already confirmed is available. The staff can also point you to tools or materials you might not have thought of—for example, the right sealant or wrench for your particular job.

Tools and equipment beyond parts

Gateway Supply stocks plumbing tools and equipment alongside parts: pipe wrenches, basin wrenches, tubing cutters, crimpers, and threading tools. They also carry safety gear, work gloves, and protective equipment. If you're renting tools rather than buying, ask whether the store offers rentals or can recommend a local tool rental shop.

For one-time projects, renting a tool often makes more sense than buying. A pipe threader or crimper might cost $100 to $300 to buy but only $15 to $30 per day to rent. Gateway Supply staff can advise on whether a tool is worth owning or renting based on how often you'll use it.

Working with a plumber who uses Gateway Supply

If you hire a licensed plumber, they may purchase parts from Gateway Supply and add the cost to your bill. Ask your plumber where they source parts and whether you can see the receipt—this shows you exactly what was installed and what you paid for materials versus labor. Some plumbers have preferred suppliers and may get contractor discounts that benefit you.

If you're buying parts yourself to hand to a plumber, confirm the specifications with them first. A plumber knows exactly what will work with your existing system, and buying the wrong part wastes time and money. Text them a photo of what you're considering, or bring them along to the store if you're unsure.

Frequently Asked Questions

Do I need a contractor license to shop at Gateway Supply?

No. Gateway Supply serves both homeowners and professionals. You can walk in and buy one part or a full bathroom's worth of fixtures. Contractor pricing and account terms may require a license, but retail purchases do not.

What if Gateway Supply doesn't have the part I need?

Ask staff whether they can order it and how long it will take. Many distributors can get specialty items within a few days. If you need it urgently, ask for recommendations on where else to look—they may suggest another local supplier or an online retailer that stocks it.

Can I return parts if I buy the wrong size?

Return policies vary by location and product type. Plumbing parts are often non-returnable once opened or installed, so confirm the policy before you buy. If you're unsure about the size, ask staff to double-check before you leave the store.

Do they sell water heaters and major fixtures, or just parts?

Gateway Supply stocks both. They carry water heaters, toilets, sinks, and faucets alongside smaller components. Prices on major fixtures are typically wholesale or near-wholesale, especially if you're a contractor.

What's the difference between shopping at Gateway Supply versus a big-box hardware store?

Gateway Supply specializes in plumbing, so their staff know plumbing better and stock deeper inventory of specialty items. Big-box stores are convenient for quick trips and carry basics, but they often don't stock professional-grade tools or hard-to-find parts. Choose based on what you need and how much time you have.
