Summer Plumbing Prep for DFW Homeowners: 6 Things to Check Before July

I've been doing home services in the Park Cities and North Dallas for years, and I can tell you — summer doesn't sneak up on your plumbing. It hits hard. The combination of intense heat, clay soil expanding under your slab, and constant irrigation demand is a recipe for trouble if you haven't done your spring plumbing walkthrough. Most of these checks take 30 minutes or less, and catching a problem in May costs a fraction of what it costs in August when everything is maxed out.

1. Check Your Irrigation System First

What to check: Your irrigation system sat mostly dormant through winter and spring, and it's about to carry a heavy load from June through September. Before you crank it up for the season, run each zone manually and walk the yard. Look for heads that don't pop up fully, zones that won't fire, or areas where water pools instead of soaking in. A broken head or clogged nozzle wastes hundreds of gallons and can drive your water bill through the roof. Also check your rain sensor — DFW gets surprise storms even in summer, and a bad sensor means your system runs right through them. That's money going straight into the gutter.

2. Inspect Your Outdoor Hose Bibs and Spigots

What to check: This one gets skipped a lot. Turn on each outdoor spigot and look for drips at the base or handle — a worn packing washer is usually a $10 fix. Also feel behind the wall where the spigot connects inside. Any dampness could mean the fitting is cracking. In North Texas we don't deal with hard freezes often, but when they hit, they tend to crack hose bibs. If yours took a hit last winter, better to find it now than when you're washing your car in July and water is going everywhere it shouldn't. If the bib is more than 10–12 years old and you're getting any drip, just replace it — they're inexpensive and the labor is minimal.

3. Flush and Test Your Water Heater

What to do: Sediment buildup in your water heater tank is normal — especially in DFW where we have moderately hard water. But if you never flush it, that sediment settles on the heating element, makes your heater work harder, and shortens its life. Attach a garden hose to the drain valve at the bottom and let it run until the water comes out clear. It takes 15–20 minutes. While you're at it, check the pressure relief valve — lift the lever and it should open and let water flow. If it doesn't move or nothing comes out, that valve needs to be replaced. A failed PRV is a safety issue, not just a maintenance miss. Water heaters are also working harder in summer when ambient garage temperatures hit 100°F+, so a stressed unit that's borderline in spring often fails in August.

4. Watch for Early Signs of a Slab Leak

What to check: Slab leaks are a DFW reality. Our expansive clay soil moves constantly — it swells when it rains, shrinks in drought — and over time that movement stresses the supply and drain lines running under your foundation. Watch your water meter when nothing is running in the house. If the dial moves, you have a leak somewhere. Also look for warm spots on tile floors, soft or damp spots in carpet, or baseboards that are bubbling or discoloring. A musty smell in a room that shouldn't be wet is another flag. Catch a slab leak early and you're looking at a targeted repair. Wait too long and you're potentially looking at foundation remediation on top of the plumbing bill.

5. Clean Your Drains Before Summer Entertaining

What to do: Summer means more people in your house — more cooking, more showers, more everything flowing down your drains. Pour boiling water down kitchen drains to cut through grease buildup, then follow with a baking soda and vinegar flush. For bathroom drains, pull the stopper and clean the hair trap — it's unpleasant but takes 3 minutes. If you've got a garbage disposal, run it with ice cubes and a half cup of kosher salt to knock off buildup on the grinding plate. A slow drain now becomes a full backup in August when you've got a house full of guests. This is the cheapest maintenance on this list and the most commonly skipped.

6. Consider a Smart Water Shutoff Valve

What to know: This is the one upgrade I've been recommending more and more in 2026. A smart shutoff valve installs at your main water line and monitors flow 24/7 using ultrasonic sensors. It learns your normal usage patterns and alerts your phone the second something looks off — and can automatically shut the water down if it detects a burst pipe or slab leak event. In a high-end home in University Park or Highland Park where you're dealing with significant water damage liability, the $400–$700 installed cost of a smart shutoff is almost nothing compared to what a slab leak or burst pipe can do to hardwood floors and high-end finishes. We install these regularly as part of our MetroPlex Shield maintenance program, and I've personally seen them catch problems that would have been devastating if they'd gone unnoticed for even a few hours.

If you're in Park Cities, University Park, or Highland Park and want us to walk through your plumbing before summer, give Creative Constructors a call. We handle everything from irrigation system tune-ups to slab leak detection and smart water shutoff installations. Don't wait for July to find out what May should have caught.
