Extreme heat can be just as tough on your plumbing as cold weather is in other parts of the country. High temperatures put extra stress on pipes, water heaters, and outdoor fixtures — and increased water usage during summer months can push your system to its limits. A little preparation goes a long way toward avoiding costly repairs.
Start with your water heater. During hot months, incoming water is already warmer, so your water heater doesn’t have to work as hard. Consider lowering the thermostat a few degrees to reduce energy costs and ease wear on the unit. This is also a great time to flush the tank and remove sediment buildup, which improves efficiency and extends the life of your heater.
Outdoor plumbing needs attention too. Exposed pipes, hose bibs, and irrigation lines can suffer from UV damage and thermal expansion when temperatures climb. Inspect exposed pipes for signs of cracking or warping, and consider adding insulation or UV-protective covers. Make sure sprinkler heads and irrigation connections are secure — the constant on-and-off cycling during summer watering schedules can loosen fittings over time.
Higher water demand in summer also means your sewer and drain systems are working harder. More showers, laundry loads, and outdoor water use can strain older pipes and septic systems. Watch for slow drains, gurgling sounds, or unpleasant odors — these can be early signs of a backup. Scheduling a professional drain cleaning before peak summer is a smart preventive move.
Finally, keep an eye on your water bill. A sudden spike often indicates a hidden leak, which can worsen quickly in hot weather as soil shifts and dries out around underground pipes. If you notice unexplained increases in usage, call a licensed plumber to inspect your system before a small leak becomes a major problem.
