Commercial Drain Cleaning in McAllen, TX

Every commercial drain slows down eventually. What matters is whether you catch it as a sluggish sink or discover it as water spreading across the floor during a lunch rush. Reliable Plumbing provides drain cleaning in McAllen for businesses of every size, from single storefronts to multi-tenant buildings, and blocked lines are part of the commercial repairs we answer 24/7.

  • Leaks and Supply Lines

    Supply lines carry pressurized water to every fixture in the building. A pinhole leak behind a wall, a cracked fitting above a ceiling tile, or a worn connector under a sink can waste water for weeks before anyone notices a stain or a soft spot in the drywall. Repair means finding the source, isolating it, and replacing the failed section or fitting.

  • Valves and Shutoffs

    Isolation valves let you cut water to one area without shutting down the whole building. When those valves seize, drip, or will not close fully, a simple fixture repair becomes a building-wide shutoff. Replacing them restores that control.

  • Restroom and Kitchen Fixtures

    High-traffic fixtures wear out faster than residential ones. Flush valves that run constantly, faucets that will not shut off, loose wall-mounted toilets, and leaking sink drains are common calls in offices, stores, and restaurants.

  • Damaged Pipe

    Corrosion, shifting slabs, and physical damage during other work can crack or separate pipe. Some of these failures are visible right away. Others only show up as a pressure drop, a water bill that jumps, or a drain that starts acting up.

When the problem turns out to be a blocked line rather than a broken one, our commercial drain cleaning service takes over. If hot water is the issue, it moves to water heater repair in McAllen.

Where Commercial Drains Clog

Different parts of a building clog for different reasons. Where the backup happens usually says a lot about what is causing it.

  • Kitchen Lines

    Fats, oils, and grease leave the sink as a warm liquid and cool into a solid inside the pipe. Food particles stick to that coating, and over months the opening narrows until water barely moves.

  • Restroom Lines

    Paper towels, feminine products, and wipes are the usual problems here. In a public or employee restroom, you have little control over what gets flushed, so these lines need attention more often than you might expect.

  • Floor Drains

    Mop water, dirt, sand, and debris tracked in from outside settle in floor drains in kitchens, garages, and warehouses. Many of these drains also sit unused for long stretches, which brings its own problems with odor.

  • Main Lines

    The main line carries everything from the building to the city sewer. When it blocks, the clog is no longer one fixture's problem. Several drains back up at once, often starting at the lowest point in the building.

Business Acquisition Financing

Commercial real estate financing allows businesses to purchase, refinance, or expand the property they operate from instead of continuing to lease. This financing builds long-term equity while spreading the purchase cost over a manageable term. Owner-occupied and investment property options are both available.

Business acquisition financing helps buyers fund the purchase of an existing business, franchise, or ownership stake. This financing is structured around the value and performance of the business being acquired, alongside the buyer's qualifications. It's commonly used for franchise purchases, independent business acquisitions, and partner buyouts.

A business line of credit provides ongoing access to funds up to a set limit, with interest charged only on the amount drawn. This flexibility makes it a practical tool for managing cash flow gaps, unexpected expenses, or time-sensitive opportunities. As funds are repaid, the available credit typically replenishes for future use

Commercial Plumbing Repair

Plumbing Repair Icon

Leaking supply lines, failing valves, broken fixtures, and damaged pipe all fall under general repair. Our commercial plumbing repair service covers the day-to-day failures that keep a building from running normally, including emergency calls at any hour.

Water Heater Repair

Restaurants, salons, gyms, and offices depend on steady hot water. When a unit stops heating, leaks at the tank, or cannot keep up with demand, water heater repair gets it back into service.

Grease, food waste, paper products, and sediment build up in commercial drains faster than in a home. Drain cleaning clears floor drains, sinks, restroom lines, and main lines so water moves the way it should.

Clearing the Line Versus Scouring It

Most clogs can be opened with a drain cable, a rotating cutter fed through the pipe to break through the blockage and restore flow. That is the right tool for a single obstruction.A cable opens a path, though. It does not remove the layer of grease or scale lining the pipe walls. When a kitchen line or main line has years of buildup, hydro jetting for commercial lines cleans the full interior of the pipe with high pressure water instead of punching a hole through the middle.

If the same drain keeps backing up after cleaning, the cause may be inside the pipe rather than in it. A camera inspection of the line shows whether you are dealing with buildup, roots, or a damaged section.

Keeping Drains Moving Between Visits

A few habits make a real difference in how often a commercial drain needs service.



Scrape plates into the trash before washing, and keep grease out of sinks entirely. Fit hand sinks and floor drains with strainers or screens, and empty them regularly. Post a sign in restrooms asking people to flush only toilet paper. For floor drains that rarely see water, pour a bucket down them every week or two to keep the trap filled.


None of this replaces cleaning, but it can stretch the time between calls.

Drain Cleaning FAQ

  • Why does a floor drain smell like sewer gas?

    Every floor drain has a trap that holds a small amount of water to block sewer gas from rising into the room. When a drain goes unused, that water evaporates and the seal disappears. Pouring about a gallon of water into the drain refills the trap. If the smell returns quickly, the trap may be cracked or the drain may need cleaning.

  • Why are several drains backing up at the same time?

    When more than one fixture backs up, the blockage is almost always downstream of all of them, usually in the main line. Water rises first at the lowest fixture, such as a ground floor floor drain or toilet. Stop using water in the building as much as possible until the line is cleared.

  • Are chemical drain cleaners safe for commercial plumbing?

    They are a poor choice. Caustic and acid-based products can damage older pipe and fittings, they rarely dissolve grease fully, and they leave a hazard for whoever opens the line next. If a product has already been poured into a drain, say so when you call so the plumber can take precautions.

  • Can flushable wipes cause clogs?

    Yes. Wipes marketed as flushable do not break apart in water the way toilet paper does. In commercial lines, they tend to combine with grease and other debris into dense masses that block the pipe, especially in main lines and at bends.

  • Will a cleaned drain clog again?

    It depends on what caused the clog. A one-time obstruction, like a dropped object, usually does not return. A line with heavy buildup on the walls, root intrusion, or a sag where waste collects will keep clogging until that underlying condition is dealt with.
