Searching for reliable plumbing in Rockwall, TX? Whether you're dealing with a stubborn clogged drain, a water heater on its last legs, a slab leak threatening your foundation, or a burst pipe at 2 a.m., Larry's Plumbing has served Rockwall, TX homeowners and businesses since 1970 — three generations, one local family, zero franchises. This guide covers every major plumbing service available in Rockwall, TX, what each one costs, and how to know when to call.
Full-Service Plumbing in Rockwall, TX: What We Do
Larry's Plumbing is a full-service plumbing company based in Rockwall, TX. Our licensed master plumbers handle everything from routine maintenance to complex commercial installations. Here's a complete breakdown of what we offer:
Drain Cleaning & Hydro-Jetting
Slow drains are the most common plumbing call we receive in Rockwall, TX. Hair, grease, soap scum, mineral scale from hard water, and tree root intrusion all cause blockages that household chemicals can't touch. We use three professional-grade methods:
- Hydro-jetting: High-pressure water (up to 4,000 PSI) scours the pipe interior clean — roots, grease, and scale removed completely. The gold standard for recurring drain problems.
- Flex-shaft drain cleaning: A rotating cable system that cuts through soft blockages quickly without damaging older pipes.
- Camera inspection: Before recommending any invasive repair, we send a waterproof camera down the drain to see exactly what we're dealing with. No guesswork, no unnecessary digging.
Rockwall, TX's hard water is particularly tough on kitchen drains — calcium and mineral deposits build up inside pipe walls over time, reducing flow to a trickle. Annual professional drain cleaning is one of the best investments a Rockwall homeowner can make.
Water Heater Repair & Replacement
Water heater issues are the second most common plumbing emergency in Rockwall, TX. Cold showers, rusty water, leaks, and strange rumbling noises all signal a system in distress. Our water heater repair in Rockwall, TX service covers:
- Thermocouple and gas valve replacement (gas heaters)
- Heating element replacement (electric heaters)
- Anode rod inspection and replacement
- Full tank flush to remove sediment buildup
- Pressure relief valve replacement
- Full tank replacement (40-, 50-, and 75-gallon units)
- Tankless water heater installation and conversion
Rockwall's hard water is notoriously hard on tank-style water heaters — sediment builds up faster here than in most Texas markets, reducing efficiency and shortening lifespan. We typically recommend annual tank flushing for all Rockwall, TX water heaters.
Leak Detection
Hidden leaks are expensive. A slow leak inside a wall cavity or beneath a concrete slab can go undetected for months, causing structural damage, mold growth, and water bills that climb 20–40% above normal. Our Rockwall, TX leak detection service uses:
- Electronic acoustic detection to listen for water escaping under pressure through pipe walls
- Thermal imaging to identify moisture patterns behind walls and under flooring without demolition
- Pressure testing to isolate sections of the plumbing system and confirm leak location before any cutting begins
Slab leaks are particularly common in Rockwall, TX due to expansive clay soils that shift with seasonal moisture changes, stressing pipes embedded in the foundation. If your water bill has spiked without explanation, call for a leak detection inspection before the damage compounds.
Emergency Plumbing — 24/7 Response
Plumbing emergencies don't follow business hours. A burst pipe, a sewage backup, a water heater that's flooding your utility room — these situations demand an immediate response. Larry's Plumbing provides true 24/7 emergency plumbing service throughout Rockwall, TX and surrounding communities. No answering service. No next-day callbacks. A licensed plumber answers the phone.

Commercial Plumbing in Rockwall, TX
Larry's Plumbing serves restaurants, retail spaces, office buildings, and industrial facilities across Rockwall, TX. Commercial systems operate at higher volume and under tighter code requirements than residential plumbing — our licensed master plumbers are equipped for both.

- Commercial water heater installation (including large-capacity and tankless systems)

Backflow Testing (TCEQ-Certified)
All commercial properties in Rockwall, TX with irrigation systems or other potential cross-connections are required by the Texas Commission on Environmental Quality (TCEQ) to have their backflow prevention assemblies tested annually. Our Rockwall, TX plumbers hold TCEQ-certified backflow tester credentials — we handle the test, the paperwork, and the city filing.
Whole-House Water Filtration
Rockwall, TX sits in one of the hardest water markets in North Texas. Municipal water in Rockwall typically measures 15–25 grains per gallon of hardness — aggressive enough to scale water heaters, clog fixtures, and reduce the life of every water-using appliance in your home. We install and service:
- Halo 5 whole-house water treatment systems — our most popular whole-home solution, addressing hardness, chlorine, and contaminants at the point of entry
- Salt-based water softeners
- Reverse osmosis drinking water systems
