Coupland is a small, unincorporated community in Williamson County, and that rural, farming-town character shapes the plumbing work we do here every day. A lot of properties in and around Coupland are older farmhouses and acreage homes built on private well and septic systems rather than city water and sewer. That means the plumbing challenges look different than what you'd find in a dense Austin subdivision — well pressure tanks that need attention, septic lines that have to be treated carefully, and original pipe materials that have been in the ground for decades.

Since our own shop sits right here at 116b Hoxie St, we're not learning this community from the outside. We drive these same farm roads, we know which parts of town tend to have harder water, and we've worked on more than a few of the older farmhouses that give Coupland its small-town character. That local familiarity, combined with being genuinely close by, means we can often get to a Coupland job faster than anywhere else we serve — and we show up already understanding the kind of plumbing system we're likely to find.

• Plumbing Maintenance: Plumbing issues rarely happen out of nowhere — they build up over time. Our plumbing maintenance helps catch small problems early, like slow drains, worn valves, pressure issues, and minor leaks, before they turn into expensive repairs. It's a great option for homeowners, landlords, and businesses who want fewer surprises.
• Drain Cleaning: Slow drains and recurring clogs are usually caused by grease, soap buildup, hard water scaling, or debris trapped in the line. We clear kitchen, bathroom, and main sewer drains thoroughly so the problem doesn't come right back. Most drain issues can be resolved in a single visit.
• Sewer Repair and Replacement: If multiple drains are backing up or you're dealing with repeated clogs, the issue may be in the main sewer line. In Austin, tree roots and aging sewer lines are common causes of sewer damage. We diagnose the problem, explain repair options clearly, and restore proper flow as quickly as possible.
• Leak Detection and Repair: Leaks aren't always obvious — many show up as higher water bills, damp spots, low water pressure, or the sound of running water when nothing is on. We locate the source of the leak and repair it properly to prevent water damage and mold. Whether it's under a sink or behind a wall, we focus on accurate diagnosis first.
• Repiping Services: Older plumbing systems can lead to frequent leaks, low pressure, discolored water, or repeated pipe repairs. Repiping replaces failing lines with new, reliable piping designed to last. We walk you through the best approach for your home and complete the work with minimal disruption.
• Sump Pump Services: A sump pump is your first line of defense against flooding when heavy rain hits. We install, maintain, and repair sump pumps to help protect basements, crawl spaces, and low-lying areas from water intrusion. If your pump fails, we can diagnose the issue quickly and restore protection.
• Water Heater Repair and Replacement: Hot water problems are often caused by sediment buildup, worn components, or hard water damage — especially in Austin. We repair and replace both tank and tankless water heaters, and we help you choose the right unit for your household's needs. Many repairs can be completed the same day.
• Fixture Repair and Installation: Dripping faucets, loose fixtures, and leaking showerheads waste water and can drive up your bill over time. We repair and install sinks, faucets, shower fixtures, and more — making sure everything is sealed correctly and working the way it should. It's one of the fastest ways to improve comfort and prevent damage.
• Backflow Testing and Prevention: Backflow issues can allow contaminated water to flow into the clean water supply, which is why testing and prevention are so important. We provide backflow testing, repairs, and prevention solutions for homes and commercial properties. Our goal is to keep your water supply safe and code-compliant.
• Hydro Jetting: Some clogs are too severe for standard drain clearing — especially when grease, roots, or heavy buildup are involved. Hydro jetting uses high-pressure water to fully clean the inside of sewer lines and restore proper flow. It's one of the most effective solutions for recurring drain and sewer problems.
• Water Treatment and Filtration: Austin's water can be tough on plumbing, appliances, and fixtures due to mineral content and hard water buildup. We install and maintain water filtration and treatment systems to improve water quality and reduce scaling. Cleaner water can also help extend the life of your plumbing system.
• Toilet Repair and Installation: A running toilet, weak flush, or frequent clogs usually points to worn internal parts or a deeper drain issue. We repair common toilet problems and install new toilets with proper sealing and leak prevention. In many cases, toilet repairs can be handled in one visit.

1. Discovery & Consultation

We begin with a detailed phone or on-site consultation to understand your needs and goals—whether it's low well pressure at a farmhouse outside town or installing a gas line for a new outdoor kitchen. We take the time to listen, ask the right questions, and assess your current plumbing situation so we can recommend the best solution.

2. Design & Proposal

Once we've identified the issue or project scope, we prepare a transparent, itemized estimate with a clear timeline. You'll know exactly what to expect before any work begins—no surprises, just honest communication and professional planning.

3. Permitting & Preparation

For larger jobs like water heater replacements, remodel plumbing, or gas line installation, we handle all necessary permits with Williamson County. We also take steps to prepare your space—laying protective coverings and ensuring the work area is clean and safe.

4. Professional Execution

Our licensed, certified plumbers carry out the work with precision and care. We arrive on time, work efficiently, respect your space, and follow all local codes and best practices to deliver lasting results you can trust.

5. Quality Check & Walkthrough

When the job is complete, we perform a thorough inspection to make sure everything meets our quality standards. We then walk you through the finished work, answer your questions, and share helpful tips for maintenance or care.

6. Post-Project Support

Our relationship doesn't end when the tools are packed up. If you have questions, need adjustments, or want to schedule future maintenance, our team is just a call away—and since we're based right here in Coupland, that's truer for our neighbors than for anyone else we serve. We're here to support you long after the job is done.

Coupland holds a special place for CMM Plumbing LLC because it's our actual home base. Our shop sits at 116b Hoxie St, and we've proudly served Central Texas since 2012 as a family-owned business built right in this small Williamson County community. There's something different about working in the town where your own shop sits — we run into familiar faces at the feed store, we know the families who've farmed this land for generations, and we take genuine pride in keeping the plumbing running smoothly for the community that's supported us for years.

Coupland's small-town, rural character is part of what makes it special. It's home to the Coupland Inn & Dancehall, a well-known local Texas dancehall and live music venue that draws visitors from across the region while still feeling like a neighborhood gathering spot. Beyond the dancehall, Coupland's roots as a farming community are still visible in the older homes, open land, and close-knit feel that define the area. It's a place where people know their neighbors, and where a plumbing company can genuinely become part of the community rather than just a service that passes through.
