In Highwood, pipes in unheated spaces — crawlspaces, garages, exterior walls — are most vulnerable during hard freezes. A pipe that freezes may not burst immediately; freeze-thaw cycling creates micro-fractures that fail days or weeks later. If you experienced a freeze event and notice reduced pressure or unexplained moisture in Lake County, professional leak detection can find damage before it becomes a larger structural problem.

Pipe freeze prevention depends on your home's construction type and local frost depth. For all homes: (1) Know where your main shutoff valve is and confirm it operates before winter; (2) Disconnect and drain garden hoses from exterior hose bibs — a connected hose traps water in the spigot and can freeze back into the supply line; (3) Insulate pipes in unheated spaces — garages, crawlspaces, and unconditioned attics. For homes in regions with frost depths below 15 inches (most of the South): (4) Let faucets drip slightly during freeze events — moving water is harder to freeze; (5) Open cabinet doors under sinks on exterior walls to allow heated room air to reach the pipes. For crawlspace homes: (6) Seal crawlspace vents before first freeze to trap ground warmth. For vacant properties: (7) Maintain minimum 55°F interior temperature or fully drain and blow out the supply system with compressed air.

PEX (cross-linked polyethylene) and copper are the two most common residential supply pipe materials used today. Key differences: (1) Flexibility — PEX is semi-rigid and can be routed around corners without fittings, reducing leak point count; copper is rigid and requires fittings at every bend, each of which is a potential failure point. (2) Freeze resistance — PEX expands under freezing and returns to shape on thaw, dramatically reducing freeze burst risk; copper does not expand and bursts when water freezes inside. (3) Corrosion resistance — PEX is immune to the electrochemical corrosion that causes copper pinholes; copper is susceptible to water chemistry attack. (4) Cost — PEX material is typically 25–40% cheaper than copper. (5) Lifespan — PEX has a projected 50+ year service life with limited field data beyond 25 years; copper has a demonstrated 50–70 year track record. (6) Heat tolerance — copper handles high-temperature water better; PEX has a maximum service temperature of 200°F.

Tree roots are a primary cause of sewer and drain line failure but rarely breach pressurized supply lines directly. The mechanism differs by line type: For drain and sewer lines — roots seek moisture and enter through pipe joints, cracks, or defects in clay tile, cast iron, concrete, or Orangeburg pipe. Once inside, they grow to fill the pipe diameter. For supply lines — roots can encircle and compress older metallic pipes over decades, causing deformation at joints. They can also cause joint separation through root growth pressure, particularly in older galvanized or lead pipe systems. For irrigation lines — roots seeking moisture are a common cause of drip emitter failure and shallow poly pipe breaches. The tree root risk radius is approximately equal to the tree's drip line (the canopy edge) for actively growing roots, but larger established root systems may extend 2–3× the drip line.

Texas has the highest rate of residential slab leak detection calls of any US state, driven by a specific combination of factors: (1) Soil — the Texas Blackland Prairie and Gulf Coast Prairies sit on Vertisol clay soils with Plasticity Index values of 40–65, among the highest shrink-swell potential soils in the world. These soils undergo 3–6 inches of vertical movement per year between wet and dry seasons. (2) Construction — approximately 95% of Texas homes are built on slab foundations directly in contact with this soil, placing copper supply pipes in direct contact with soil that is constantly moving. (3) Climate — Texas experiences extended summer droughts that maximize soil desiccation and movement, followed by heavy rainfall that causes rapid re-expansion. (4) Pipe era — the bulk of the Texas housing stock was built between 1960 and 1990 with copper supply pipe that now has 30–60 years of service on highly mobile soil.

The Uniform Plumbing Code and International Plumbing Code both specify a maximum service pressure of 80 PSI for residential supply systems. Most appliance manufacturers void warranties on washing machine hoses, refrigerator water lines, and water heater supply valves at pressures above 80 PSI. Dishwasher fill valves and toilet fill valves are similarly rated for 80 PSI maximum. The optimal range for residential plumbing is 50–70 PSI — sufficient for good shower pressure and appliance performance while keeping stress on fittings and fixtures within safe limits. Below 40 PSI, shower performance degrades and some appliances may not fill correctly. Testing water pressure requires a simple gauge threaded onto a hose bib — available for under $15 at any home improvement store.

A moving meter with no visible leak almost always means the leak is hidden — either inside walls, under the slab, underground between the meter and the house, or in an irrigation system branch. The most common locations for hidden leaks detected this way are: (1) slab supply lines under the concrete floor; (2) underground service line between the meter and the house foundation; (3) toilet flappers (though these are more commonly caught by dye testing than meter observation); (4) outdoor irrigation zone valves that fail to close fully. The next diagnostic step is to isolate the leak to a specific zone by closing the main shutoff valve inside the house and observing whether the meter continues to move — if it does, the leak is between the meter and the house on the service line.

Summer creates several distinct leak drivers that make July and August peak months for certain leak types: (1) Peak water demand — irrigation, pools, and increased usage push system pressure to seasonal highs that stress aging pipe fittings; (2) Soil desiccation — in clay soil regions, summer drought causes maximum shrinkage, creating soil movement that stresses slab-embedded and buried pipes; (3) Thermal expansion — copper supply lines experience their maximum annual thermal expansion in summer, stressing joints; (4) Irrigation system activation — irrigation systems that have been off all winter often reveal cracked heads, failed zone valves, and failed backflow preventers when restarted in spring/summer; (5) Pool and outdoor plumbing use — outdoor plumbing that is inactive in winter begins operating again, and winter-damaged fittings fail under pressure.

Slab leaks occur when a water supply or drain line embedded in a concrete foundation develops a breach. The three primary causes are: (1) soil movement — expansive clay soils shrink and swell seasonally, stressing pipe joints and bending copper lines over time; (2) pipe corrosion — copper pipes embedded in concrete are exposed to alkaline pH and mineral contact that accelerates pitting; (3) water hammer — repeated pressure surges from rapid valve closures create micro-fractures at elbows and fittings. In cities built on high-shrink-swell Vertisol clay (Houston, Dallas, the Texas Blackland Prairie), soil movement is the dominant cause. In older cities with original copper runs, corrosion-driven pinhole failure is most common.
