Gateway Supply: A Plumbing Retailer in South Carolina

What Gateway Supply is and where to find it

Gateway Supply is a plumbing and HVAC distributor with locations across South Carolina. Unlike big-box hardware stores, Gateway Supply serves both professional contractors and homeowners, stocking specialized plumbing parts, fixtures, and tools that you might not find at a general retailer. The company operates multiple locations throughout the state, making it a regional option for plumbing materials and advice.

Gateway Supply's model centers on serving the trade—plumbers, HVAC technicians, and builders who need reliable stock and fast turnaround. But homeowners tackling their own repairs or renovations can also shop there. The stores carry everything from basic PVC and copper pipe to water heaters, faucets, valves, and diagnostic equipment. Many locations offer same-day or next-day availability on common items.

Key Takeaways

• Gateway Supply stocks both common plumbing materials and specialized parts that general hardware stores may not carry.
• The company operates multiple locations across South Carolina, so you can find a branch near you rather than ordering online.
• Staff at Gateway Supply locations typically have trade experience and can answer technical questions about pipe sizing, material compatibility, and installation.
• Homeowners and contractors both shop at Gateway Supply, though the business model prioritizes serving professional plumbers and HVAC technicians.

Types of products Gateway Supply carries

Gateway Supply stocks the full range of plumbing materials: copper and PVC pipe in various diameters, fittings, valves, shut-offs, and connectors. You'll find water heaters from major manufacturers, faucets for kitchens and bathrooms, and replacement parts for existing fixtures. The inventory also includes water treatment equipment, backflow preventers, and rough-in supplies for new construction or major renovations.

Beyond pipe and fixtures, Gateway Supply carries tools and diagnostic equipment: pipe wrenches, crimpers, cutters, leak detection kits, and pressure gauges. They stock solder, flux, tape, and other consumables that plumbers use daily. Many locations also carry HVAC supplies—ductwork, refrigerant, thermostats, and furnace parts—since the company serves both trades under one roof.

How to locate a Gateway Supply branch near you

Gateway Supply operates branches in major population centers and along the I-95 corridor in South Carolina. The easiest way to find your nearest location is to visit the company's website or call their main number to ask for the branch closest to your address. Most locations are open during standard business hours, with some offering extended hours for contractors who work early or late.

When you visit, bring the model number or description of what you're looking for—a faucet model, water heater size, or pipe diameter. If you're unsure what you need, bring a photo or the old part itself. Staff can often match it or suggest the right replacement. For large orders or specialty items not in stock, many locations can order and hold items for pickup within a few days.

Pricing and payment options

Gateway Supply's pricing reflects its role as a trade distributor. Prices are generally lower than big-box retailers for the same items, especially on bulk orders or contractor-grade materials. However, you may not see the rock-bottom prices of online-only retailers, because you're paying for local inventory, same-day availability, and staff expertise.

Most Gateway Supply locations accept cash, card, and check. Many offer contractor accounts with net-30 or net-60 payment terms for businesses that buy regularly. If you're a homeowner making a one-time purchase, you'll typically pay at the register. Ask about any current promotions or bulk discounts if you're buying multiple items for a larger project.

When to shop at Gateway Supply versus other retailers

Choose Gateway Supply when you need a specific part quickly, want to talk to someone who understands plumbing, or are buying materials for a substantial project. If you need a 1-inch copper coupling today and your local hardware store is out of stock, Gateway Supply likely has it. If you're replacing a water heater and want to compare brands and sizes in person, the staff can walk you through the options.

Shop elsewhere if you're looking for the absolute lowest price on common items, prefer to order everything online, or need supplies outside plumbing and HVAC. Big-box stores often undercut on price for basic PVC and fittings. Online retailers offer convenience and sometimes lower costs, but you wait for delivery. Gateway Supply's advantage is immediacy, expertise, and selection in one place.

What to bring when you visit

Bring the old part if you're replacing something—a faucet cartridge, valve stem, or fitting. Bring the model number if you know it, or a photo. If you're planning a project, bring measurements or a rough sketch of what you're trying to do. Write down the size and type of pipe you have (copper, PVC, galvanized steel) if you're not sure how to describe it.

If you're buying for a contractor or builder, bring any job specifications or blueprints that show what materials are needed. Gateway Supply staff can help you calculate quantities and suggest alternatives if something is out of stock. For water heater replacement, know your current tank size and fuel type (gas, electric, tankless) so staff can show you comparable options.
