Plumbing 

Plumbing problems disrupt daily life fast. Whether it’s a cold shower, a slow drain, or an unexpected slab leak, skilled plumbing service protects your home, health, and property value. Local conditions like hard groundwater, seasonal temperature swings, and expansive clay soils mean common plumbing issues require timely, experienced attention. This page explains the residential and commercial plumbing services available, common problems you’ll see in the area, how professionals diagnose and repair them, and what warranty and maintenance expectations you should have. Contact Roadrunner Plumbing & Air today for plumbing services.

Common Plumbing Problems And Service Types

Most service calls fall into predictable categories. Understanding these will help you recognize issues early and choose the right solution.

  • Water heater repair and installation (conventional and tankless).
  • Kitchen and bathroom plumbing: faucets, sinks, toilets, shower valves, bathtub drains.
  • Drain services: clog removal, hydro jetting, recurring slow drains.
  • Slab leak detection and repair.
  • Whole-home repiping (copper, PEX, CPVC).
  • Gas line services and safety inspections.
  • Backflow testing and replacement for irrigation and commercial systems.
  • Water softener and filtration system installation and maintenance.
  • Sump pump inspection, repair, and replacement.
  • Emergency plumbing response for burst pipes, major leaks, or sewer backups.
  • Commercial plumbing systems including grease traps, floor drains, and large-capacity water heaters.

Why These Problems Are Common Here

San Antonio area water tends to be hard, carrying minerals that cause scale buildup inside water heaters, fixtures, and appliances. High summer water use increases the strain on water heaters and supply lines. Older neighborhoods may have galvanized or corroded piping, and the local soils can shift with wet-dry cycles—raising the risk of slab leaks. Seasonal storms can overwhelm drainage and sump systems. Understanding these local drivers helps prioritize repairs and upgrades that deliver long-term reliability.

Diagnostic Process: How Pros Find The Real Problem

Accurate diagnosis is critical to avoid unnecessary work. Typical diagnostic steps include:

  • Visual inspection of fixtures, vents, and visible piping for corrosion, leaks, and improper venting.
  • Pressure testing to isolate leaks and confirm integrity of gas or water lines.
  • Electronic leak detection and acoustic listening devices for slab leak location.
  • Thermal imaging to find hidden temperature differences indicating leaks.
  • Sewer camera inspection to evaluate sewer lines for tree root intrusion, collapsed pipe, or blockages.
  • Water testing to determine hardness, contaminants, or pH that affect appliances and piping.
  • System performance checks on water heaters, sump pumps, and water treatment systems.

These tools let technicians propose targeted repairs, replacements, or preventive upgrades rather than guessing.

Repairs And Solutions Explained

Below are common solutions explained in everyday terms, so you know what to expect.

  • Water heaters (conventional vs tankless): Conventional tank heaters store and heat a volume of water; they’re simple to service and repair. Tankless models heat water on demand, reducing standby heat loss and saving space. For both types, technicians remove scale, replace failed components, and evaluate venting and safety devices. When replacement is recommended, installers size the unit to household demand and local gas or electric supply conditions.
  • Kitchen and bathroom plumbing: Repairs range from replacing worn cartridges in faucets to reconstructing poorly sloped drain lines. For persistent leaks or recurring clogs, evaluating and replacing corroded supply lines and drain segments can prevent repeat visits.
  • Slab leak repair: Because leaks under concrete can cause serious structural damage, professionals locate leaks using non-invasive methods (acoustic sensors, thermal imaging) and determine whether repair can be made from access points or requires localized slab cutting. Prompt repair minimizes foundation and flooring damage.
  • Whole-home repiping: When interior copper, galvanized, or polybutylene lines fail or corrode, full repiping with modern materials (commonly PEX or copper) restores consistent water quality and pressure. Technicians map the system to minimize disruption and recommend durable routing and shutoff placement.
  • Backflow testing and replacement: Backflow devices protect potable water from contamination. Testing confirms valve operation; replacement is required when devices fail to meet code or no longer seal reliably.
  • Drain and sewer services: Simple snaking works for many clogs. Hydro jetting clears grease, roots, and scale from sewer lines. Video inspection informs whether repair or pipe replacement is necessary.
  • Gas line work: Gas systems require certified inspection, pressure testing, and safe appliance connection. Any suspected leak requires immediate isolation and professional remediation.
  • Water treatment: Hard water and sediment reduce appliance life. Water softeners and point-of-entry filtration systems are sized to household consumption and local water chemistry to improve taste, extend fixture life, and reduce scale inside heaters.
  • Sump pumps: Pumps are inspected for float operation, check valves, and electrical reliability. Backup options (battery or secondary pumps) are recommended where frequent storms or low grades threaten basements.

Emergency Response And Timelines

Plumbing emergencies—burst pipes, active slab leaks, sewer backups—demand rapid stabilization. Expect emergency crews to isolate water or gas, perform temporary stop-gap repairs to prevent further damage, document conditions for insurance, and provide a clear plan for permanent repair. For non-emergency issues, same-day diagnostics and transparent repair options are the norm in established service areas.

Warranties And What To Expect

Reliable plumbing work comes with workmanship and parts warranties. Typical workmanship warranties range from short-term coverage for minor repairs to longer commitments for complex projects. Manufacturer warranties cover replacement parts and appliances; these vary by brand and component. Ask for a written summary of what the warranty covers, any maintenance required to keep it valid, and expected timelines for service requests under warranty.

Maintenance And Prevention Tips

Proactive maintenance reduces emergency risk and extends system life:

  • Flush and inspect water heaters annually to remove sediment
  • Install or maintain water softening if local water hardness is high
  • Use drain strainers and avoid flushing grease or fibrous materials
  • Test sump pumps before storm season; consider a battery backup
  • Schedule periodic sewer camera inspections for older trees or known root issues
  • Have backflow devices tested annually if required by local code

Regular inspections catch small problems before they become costly repairs and protect your home’s structure and investment.

Plumbing requires solutions tailored to local water quality, soil conditions, and home age. Clear diagnostics, appropriate materials, and prompt, warranty-backed repairs restore comfort and protect your property for years to come.

    Chris, Roberto, and Joey from San Antonio Roadrunner Plumbing and Air were absolutely top-notch! They were professional, respectful, and got the job done at a very reasonable price. They replaced my AC coil, and now my air conditioner is working like new! Before finding them, I was stuck dealing with First American Home Warranty, and it was a nightmare. The contractor they sent out, Extreme Air Experts, was anything but expert. Total waste of time.I’m beyond grateful I found Roadrunner — they’ve earned my trust, and I’ll be using them for all my future HVAC needs. Highly recommend!

    I have used Roadrunner Plumbing for over 10 years and always get prompt, professional service and repairs. They communicate clearly and deliver a high quality result for a fair price. I wouldn’t trust anybody else. Here’s some pictures of the pressure reducing valve they replaced. The plumber Jonathan Evans showed up on time and was done in about an hour. First class operation and plumbers.

    Luis Rico with Roadrunner Plumbing & Air came out last week to evaluate a list of issues that needed some attention in my home. I was given 2 estimates with different options, which i appreciated. He was able to come back the following day with all the replacement items, and along with an assistant, Chance, completed all the work in about 4 hours. Luis & Chance were polite, knowledgeable and efficient, and I will be using Roadrunner again for any future plumbing needs. Thanks guys!😊
