Philadelphia summers are hot, humid, and hard on your home's plumbing. From increased water usage during backyard entertaining to the stress that ground temperature changes put on your pipes, summer brings a unique set of plumbing challenges. Here's what every homeowner in the Philadelphia area should know heading into the warm months.
Watch for Increased Water Pressure Fluctuations
Summer is peak water usage season for municipal systems, especially during heat waves when everyone runs sprinklers, fills pools, and takes more showers. High demand on the water main can cause pressure fluctuations that stress your home's supply lines and fixtures. If you notice water pressure that's inconsistent or noticeably different from normal, it's worth having a plumber check your pressure reducing valve (PRV). Ideal home water pressure is 40–60 PSI; anything above 80 PSI can damage fixtures and accelerate pipe wear.
Outdoor Hose Bibs and Irrigation Systems
After a winter of being shut off, outdoor faucets and irrigation systems need attention before heavy summer use. Check hose bibs for drips — even a small drip can waste thousands of gallons over a summer. Inspect irrigation system heads for proper coverage and look for sprinkler heads that are watering sidewalks or driveways rather than your lawn.
Garbage Disposal Care During BBQ Season
Summer means more outdoor entertaining and more kitchen scraps. Corn cobs, watermelon rinds, peach pits, and meat fat are all disposal killers. Keep a trash can handy for solids and remember the golden rule: if in doubt, throw it out (in the trash, not the drain). Run cold water for 15 seconds before and after using the disposal.
Water Heater Efficiency in Summer
Here's a money-saving tip most homeowners miss: dial back your water heater temperature to 110–115°F in summer. You don't need scalding water when the incoming cold supply is already 65–70°F. This simple adjustment can meaningfully reduce your water heating costs during the summer months.
Prepare Before You Vacation
Going away for a week or more? Take these precautions:
- Turn off the main water supply or at least shut off the supply to the washing machine — one of the most common causes of flooding in vacant homes.
- Set your water heater to "vacation mode" to save energy.
- Ask a neighbor to check in periodically.
- Consider a smart water leak detector — these $30–50 sensors can alert you to a leak on your phone before it becomes a flood.
Sewer Line and Drain Alert: Summer Root Intrusion
Tree roots are most aggressive in summer, actively seeking water sources — including your sewer line. If you have mature trees near your home, summer is peak season for root intrusion issues. Slow drains throughout the house (not just one fixture) are a classic warning sign. A camera inspection can confirm whether roots are the culprit before you have a full blockage.
Protect Your Sump Pump
Philadelphia summers bring intense thunderstorms. If your home has a sump pump, test it now by pouring a bucket of water into the pit to confirm the float triggers properly. Check the discharge line to make sure it's clear and directing water away from your foundation. If your sump pump is more than 7–10 years old, consider adding a battery backup — storms often knock out power at the exact moment your pump is working hardest.
Signs of a Hidden Leak to Watch For
Increased summer water bills sometimes get blamed on irrigation, but they can mask a hidden leak. Suspect a leak if your water bill has spiked significantly and you haven't made obvious changes to your usage patterns. Check your water meter before bed, don't use any water overnight, and recheck in the morning — any movement indicates a leak somewhere in your system.
