Plumbing Services We Provide in Flower Mound

At Horizon Plumbing, we cover the plumbing issues Flower Mound homeowners deal with most, from a clogged drain to a full sewer line repair, with a clear explanation of cost before we start.

Drain Cleaning. Slow or backed up drains usually trace back to grease buildup, soap scale, or root intrusion narrowing the pipe. We use hydro jetting and camera inspection to clear the line and confirm the cause instead of guessing.

Leak Detection. Hidden leaks behind walls or under slabs waste water and quietly damage a home’s foundation. Our leak detection equipment pinpoints the source without tearing out drywall or flooring to go looking for it.

Water Pressure Testing and PRV Service. Pressure that runs too high stresses every fixture in a home even when nothing looks wrong. We test static pressure at the meter and install or repair the pressure reducing valve when a reading comes back above code limits.

Water Heater Repair and Installation. Whether a tank unit is leaking, short cycling, or simply old, we repair or replace it with equipment sized correctly for the household. As a certified Rinnai ACE dealer, we service tankless units alongside traditional tank models.

Sewer Line Repair. A sewer line that backs up into the house is not a problem to wait out. We locate the failure point with a camera first, then walk homeowners through trenchless or traditional repair options.

Slab Leak Repair. A slab leak needs a plumber who can find the exact point of failure before cutting into concrete. We locate the leak precisely, then walk homeowners through repair or reroute options based on the plumbing’s age and layout.

Fixture and Faucet Replacement. Running toilets, weak flushes, and dripping faucets waste water every day they go unaddressed. We repair or replace fixtures with water saving models, including sink and faucet upgrades, when it makes sense.

Emergency Plumbing Service. A burst pipe or failed water heater does not wait for business hours. We keep technicians available 24/7 for calls that cannot wait until morning.

Why Flower Mound’s Elevation Changes Push Water Pressure Past Code Limits

Flower Mound sits on rolling terrain anchored by the 50 foot rise the town is named for, and elevation swings like that change what a home’s fixtures experience at the tap. Municipal systems are built to guarantee adequate pressure at the highest points they serve, which means homes sitting lower in that system, closer to a pump station or lower on the grade, often receive static pressure well above what residential fixtures are designed for.

Flower Mound has adopted the 2024 International Plumbing Code as its official plumbing code, and that code sets a hard limit here. Under IPC Section 604.8, where water pressure inside a building exceeds 80 psi static, an approved pressure reducing valve conforming to ASSE 1003 must bring the building’s distribution piping down to 80 psi or less. Most plumbers then set that valve closer to 60 to 70 psi, building in a margin instead of running at the ceiling.

Where a home lacks a PRV, or an existing one has failed open unnoticed, that excess pressure works on every joint, gasket, and appliance connected to the supply line around the clock. Supply lines develop pinhole leaks earlier than they should, fill valves and washing machine hoses fail without warning, and a water heater’s relief valve can begin weeping as it compensates for pressure it was never sized to handle.

We at Horizon Plumbing test static pressure at the meter on service calls across Flower Mound rather than assume a home’s pressure falls in a safe range. When a reading comes back above 80 psi, we install or replace the pressure reducing valve and recheck before considering the job finished, instead of treating only the symptom that brought us out.

What Flower Mound Customers Say About Horizon Plumbing

A Pressure Problem Traced Past the Obvious Fix

A homeowner had lived with weak, inconsistent water pressure for some time, unsure whether the fixtures themselves were to blame or something further back in the system.

“For quite some time, we had a problem with low water pressure. Lane to the rescue!!! He not only solved the problem with a new pressure release valve, but he also correctly found a way to install our water turn shut-off valve in our garage (it was poorly installed in the front yard, go figure) with minimal upheaval in terms of dry wall cutting.”

Lane Copeland’s approach reflects how our technicians handle pressure related calls generally: find the actual cause before assuming it is the obvious one, and stay on the job until every downstream symptom gets resolved. Read Susan’s full Google review.

A Leak Found on the First Visit After Years of Frustration

Another homeowner had grown skeptical of plumbers after years of repairs that never quite stayed fixed, and needed someone to actually locate the leak rather than patch around it.

“In 25 years I haven’t been able to find a plumbing service that I would call back to do another repair but I have found one now. Jose did a great job tracking the source of the leak, and fixing the problem. His communication and professional were fantastic.”

Jose Castro’s diagnostic approach is standard practice on leak calls: locate the actual source before opening a wall or slab, so the repair addresses what actually failed. Read Jeff’s full Google review.

Frequently Asked Questions About Plumbing Services in Flower Mound, TX

How do I know if I need a plumber in Flower Mound? 

Warning signs include water pressure that feels unusually strong at every fixture, a water bill that has crept up without an obvious reason, a toilet that runs long after flushing, or any damp spot on flooring, drywall, or ceiling that was not there before. Any of these on their own is worth a call before the underlying problem gets worse.

Do you test water pressure and check for leaks before starting a repair? 

Yes. We check static pressure at the meter and, where a leak is suspected, use leak detection equipment to locate the source before recommending a fix, so the repair addresses the actual cause instead of the symptom.

Is there a trenchless option for repairing a damaged sewer or water line? 

In many cases yes. Depending on the extent of the damage and the layout of the line, we can often repair or reline a section without excavating the entire yard, which we confirm once we have located the exact point of failure.

How do I decide between repairing my water heater and replacing it? 

If the unit is younger than eight years old and the failure is isolated to one part, such as a thermostat or heating element, repair usually makes sense. Units older than ten years or showing multiple issues at once are typically more cost effective to replace.

What causes plumbing problems specifically in Flower Mound? 

Flower Mound’s rolling terrain means static water pressure varies significantly across town, and homes without a properly functioning pressure reducing valve can run well above the 80 psi limit set by the plumbing code. Over time that excess pressure stresses supply lines, fixture connections, and water heater relief valves in ways homeowners do not notice until something fails.
