Larry's Plumbing offers a complete range of residential and commercial plumbing services to homeowners and businesses in Rockwall, TX. Our licensed technicians handle everything from a dripping faucet to a full-building commercial plumbing installation.
Drain Cleaning in Rockwall, TX
Clogged drains are the most common plumbing service call in Rockwall. Whether it's a slow bathroom sink, a backed-up kitchen drain, or a completely blocked main sewer line, Larry's Plumbing clears it fast and completely.
What we use:
- Flex-shaft drain machines — the most effective mechanical drain cleaning method available, physically removing blockage material from pipe walls
- Hydro-jetting — high-pressure water scour for grease-heavy kitchen lines and severely scaled pipes
- Camera inspection — for recurring clogs, we scope the line to find root intrusion, bellied pipe, or structural damage causing the problem
Rockwall, TX homeowners with older homes (pre-1990s) often have clay sewer lines or cast iron drain pipes that are especially vulnerable to root intrusion and buildup. If your drain clogs keep coming back, a camera inspection will show exactly why.

Water Heater Repair and Replacement in Rockwall, TX
Water heater problems show up in predictable ways: no hot water, lukewarm water that runs out fast, rust-colored water, popping or rumbling sounds from the tank, or water pooling at the base of the unit.
Rockwall, TX's moderately hard water accelerates sediment buildup inside water heater tanks — shortening their effective lifespan compared to areas with softer water. Annual flushing extends tank life significantly.
Our Rockwall water heater services include:
- Standard tank water heater repair (all major brands)
- 40, 50, and 75-gallon tank replacement
- Tankless water heater installation and service
- Expansion tank installation (required by Rockwall code for closed plumbing systems)
- Anode rod replacement and annual maintenance
Most water heater replacements in Rockwall, TX are completed in 2–3 hours. We haul away the old unit.

Leak Detection in Rockwall, TX
Rockwall, TX sits on expansive clay soil that swells when wet and contracts during drought — causing constant, subtle movement under slabs and around foundations. This foundation movement stresses underground water supply lines, making slab leaks unusually common in Rockwall-area homes.
Signs of a slab leak or hidden pipe leak in your Rockwall home:
- Your water bill has increased without explanation
- You hear water running inside walls or under floors when everything is off
- Hot spots on your floor (warm slab from a hot water line leak)
- Cracks appearing in your drywall or flooring
- Your water meter is moving when all fixtures are off
Larry's Plumbing uses non-destructive leak detection methods — electronic listening equipment and pressure testing — to pinpoint exactly where a leak is before any cutting or opening begins. We don't tear open walls to go looking.
Once located, we provide options: spot repair (opening only where the leak is), reroute (running a new line through the attic or walls to bypass the damaged section), or full repipe (for homes with widespread pipe deterioration).
