Marble Falls, TX

Plumber in Marble Falls, TX

Knockout Plumbing Services is the Highland Lakes’ trusted licensed plumber, serving Marble Falls homeowners and businesses with honest, expert plumbing service.

Marble Falls is the economic hub of the Highland Lakes, a growing city of approximately 7,000 residents that serves as the commercial and service center for the broader region. As the largest city in the Highland Lakes, Marble Falls has a diverse housing stock ranging from historic downtown homes built in the early 1900s to modern lakefront developments and new construction subdivisions. Each era of construction presents its own plumbing challenges, and Knockout Plumbing Services has the experience and expertise to handle all of them.

Plumbing in Marble Falls: The Hard Water Challenge

Every plumber who works in Marble Falls knows that the water here is different. The water supplied by the City of Marble Falls, drawn from Lake Marble Falls and treated at the city’s water treatment plant, is some of the hardest water in Texas. With mineral content typically ranging from 15 to 25 grains per gallon (GPG), Marble Falls water is two to three times harder than the national average and well above the 10.5 GPG threshold that water quality experts classify as “very hard.”

This hard water is not a health concern, it is safe to drink and use. But it is a significant concern for every pipe, appliance, and fixture in a Marble Falls home. The calcium and magnesium minerals dissolved in the water deposit on every surface they contact, building up over time as the white, chalky scale that is familiar to every Marble Falls homeowner. Inside pipes, this scale narrows the effective diameter and reduces water pressure. Inside water heaters, it insulates the heating element and forces the heater to work harder. Inside faucets and valves, it causes components to stick and wear faster than they should.

For homes built in the 1970s and 1980s, a significant portion of Marble Falls’ housing stock, the hard water has been attacking the copper supply lines for 40-50 years. Copper pipe in hard water conditions deteriorates through a process called pitting corrosion, where the minerals in the water create small pits in the interior wall of the pipe that deepen over time until they penetrate the pipe wall, creating pinhole leaks. Many of these homes are now experiencing their first or second round of slab leaks as this corrosion reaches the pipes embedded in or running beneath the concrete foundation.

Understanding this hard water challenge is fundamental to providing good plumbing service in Marble Falls. A plumber who treats a Marble Falls home the same as a home in Austin or San Antonio, where the water is softer, will make different material choices, different maintenance recommendations, and different repair vs. replacement decisions than one who understands the specific water chemistry of the Highland Lakes. Knockout Plumbing Services is based in the Highland Lakes and understands these conditions intimately.

Marble Falls Neighborhoods and Their Plumbing Profiles

Historic Downtown and Older Neighborhoods

The older neighborhoods of Marble Falls, the historic downtown area, the streets near the original townsite, and the established residential areas that developed through the mid-20th century, contain some of the most challenging plumbing situations in the city. Homes in these areas may have original galvanized steel supply lines that are now 60-80 years old and well past their service life in hard water conditions. They may have cast iron drain lines that are corroded and prone to root intrusion. And they may have been through multiple generations of partial repairs and updates, creating a patchwork of different pipe materials and connection types that require careful diagnosis before any repair.

For homeowners in older Marble Falls neighborhoods, we recommend a complete plumbing assessment to understand the current condition of the supply and drain systems. This assessment, which involves pressure testing, visual inspection of accessible pipe, and a review of any known problem history, provides a clear picture of what needs immediate attention and what can be monitored. It is the foundation for a sensible long-term maintenance plan that avoids emergency repairs and unexpected costs.

Mid-Century and 1970s-1980s Homes

The largest segment of Marble Falls’ housing stock consists of homes built between approximately 1960 and 1990. These homes typically have copper supply lines and cast iron or early PVC drain lines. The copper supply lines in these homes are now 35-60 years old and are at high risk of pinhole leaks and slab leaks in the hard water conditions of Marble Falls. The cast iron drain lines, if original, are also approaching the end of their service life.

Slab leaks are the most common serious plumbing problem in this generation of Marble Falls homes. The combination of aging copper pipe, hard water corrosion, and the movement of the limestone substrate beneath the slab creates conditions where slab leaks are not just possible but expected. We have repaired slab leaks in hundreds of Marble Falls homes and can locate and repair them with minimal disruption to the home.

Lakefront and Newer Developments

Marble Falls has experienced significant growth in recent years, with new residential developments along Lake Marble Falls, Lake LBJ, and in the surrounding hills. These newer homes typically have PEX supply lines and PVC drain lines, materials that are well-suited to the Highland Lakes’ hard water conditions. However, even newer homes in Marble Falls benefit from water softener installation to protect water heaters and appliances from the hard water.

Lakefront properties present some specific plumbing considerations, including the potential for well water service in areas not served by city water, the need for water treatment systems appropriate for the specific water chemistry of the well, and the challenges of plumbing in homes built on rocky lakefront terrain.

Common Plumbing Services in Marble Falls

Slab Leak Detection and Repair

Slab leaks are the most serious and most common plumbing problem in Marble Falls homes built before 1990. We use acoustic detection equipment to locate slab leaks precisely, often to within a few inches, before cutting any concrete. This precision minimizes the disruption and cost of the repair. We offer three repair approaches: targeted under-slab repair, pipe rerouting through walls or attic, and epoxy pipe lining for drain lines. We present all options with honest pricing and let you choose the approach that best fits your situation.

Water Heater Service

Water heaters in Marble Falls typically last 6-8 years without proper maintenance, less than the 10-12 year national average, because of the hard water sediment that accumulates in the tank. Annual sediment flushing and regular anode rod replacement can extend this to 10-12 years. We service all brands and types of water heaters, including tank and tankless systems, and we can advise on the right system for your home and water chemistry.

Drain Cleaning

The combination of hard water mineral scale and the organic buildup from grease, hair, and soap makes drain clogs more common and more stubborn in Marble Falls than in soft water areas. We clear drains with cable augers and hydro-jetting, and we can perform sewer camera inspections to diagnose recurring problems. For main line clogs caused by root intrusion, common in older Marble Falls neighborhoods with large trees, hydro-jetting is the most effective treatment.

Water Softener Installation

A water softener is the single most effective investment a Marble Falls homeowner can make to protect their plumbing system and appliances. By removing the calcium and magnesium minerals from the water before they enter the home’s plumbing, a softener prevents scale buildup in pipes, water heaters, and appliances, extending their service life and reducing energy costs. We install, service, and repair water softeners throughout Marble Falls and can help you choose the right system for your home.
