CMM Plumbing LLC proudly offers a 2-year warranty on labor for all completed work.
Your Central Texas Plumbing Maintenance Team
Most plumbing emergencies don’t start as emergencies. They start as a slow drip under a sink, a water heater that’s never been flushed, or a shut-off valve that’s quietly corroding away. By the time you notice the problem, it’s usually costing more to fix than it would have a year earlier. That’s the whole idea behind plumbing maintenance — a licensed plumber walks through your system on a regular basis and flags the small stuff before it turns into a burst pipe, a failed water heater, or a weekend service call.
CMM Plumbing is a family-owned company with over 20 years of experience serving Coupland and the greater Austin area, and we hold a Master Plumbing License #46268. We offer maintenance visits for both residential plumbing and commercial plumbing systems, so whether it’s a house in Coupland or a small business in Austin, we know what to look for and how to keep it running.
What’s Included in a Plumbing Maintenance Visit
Every property is a little different, so we adjust the visit based on your home or business’s age, fixtures, and history. In general, a maintenance appointment with CMM Plumbing covers:
- Inspecting and flushing your water heater (traditional or tankless) to clear sediment buildup and check for wear
- Checking supply lines and shut-off valves for corrosion, mineral buildup, or leaks
- Testing water pressure throughout the property
- Checking drains for slow-moving lines before they turn into a full clog — see our drain cleaning page for more on that
- Reviewing gas line connections and fittings for safety
- Inspecting toilets, faucets, and fixtures for wear or minor leaks
- Looking for early signs of leaks around appliances and, when needed, running a camera inspection on lines we can’t see directly
We’ll walk you through anything we find, explain what it means, and give you honest recommendations — no pressure to fix things that don’t need fixing yet.

Warning Signs It’s Time to Schedule a Maintenance Check
You don’t have to wait for a scheduled visit if something already feels off. These are common signs that your plumbing system could use a look:
- Your water heater is more than 8-10 years old and hasn't been serviced recently
- A noticeable drop in water pressure
- Drains that run slow, even after you've tried clearing them
- Water bills that have crept up without an obvious reason
- Visible corrosion or mineral buildup on pipes, valves, or fittings
- You've owned the property for a while and it's never had a plumbing checkup
None of these mean you have an emergency on your hands. They’re just the kind of thing worth having a licensed plumber take a look at before they turn into one.

Frequently Asked Questions About Plumbing Maintenance
What does a plumbing maintenance visit include?
A typical visit covers your water heater, supply lines, shut-off valves, drains, water pressure, and fixtures. We're checking for corrosion, small leaks, worn parts, and anything else that could turn into a bigger problem if it's left alone.
How often should I schedule plumbing maintenance?
Once a year is a good baseline for most homes. Older homes, homes with a tankless or traditional water heater that hasn't been flushed in a while, or properties that have had plumbing issues before can benefit from checking in more often.
Can maintenance really prevent expensive repairs?
It won't catch every possible issue, but a lot of the plumbing emergencies we get called out for start small — a slow drip, a valve that's starting to corrode, a water heater that's overdue for a flush. Catching those early is a lot cheaper than an emergency call later.
Do you offer maintenance for both homes and businesses?
Yes. We provide maintenance visits for residential properties as well as commercial plumbing systems throughout Coupland, Austin, and the surrounding Central Texas area.
What's the difference between plumbing maintenance and a repair call?
A repair call means something is already broken or leaking. A maintenance visit is preventative — we're inspecting your system before anything fails, so we can flag wear and tear while it's still a minor fix instead of an urgent one.
