Beat the Heat: 4 Ways Summer Weather Can Secretly Trash Your Plumbing
July is officially here, and with it comes sizzling temperatures, backyard barbecues, and kids running through the sprinklers. While you’re busy trying to keep cool, your home’s plumbing system is working overtime to handle the heat. Most people associate plumbing disasters with freezing winter pipes, but extreme summer heat presents its own set of unique challenges.
Here are four ways the July heatwave can impact your plumbing, and how you can prevent a mid-summer meltdown.
1. Baked Soil and Cracked Pipes
When the July sun beats down week after week, the soil around your home loses moisture and shrinks. Later, a sudden summer thunderstorm can cause that same soil to rapidly expand. This constant shifting putting immense pressure on your underground water and sewer lines.
- What to look for: A random, lush green patch in your yard, a sudden drop in water pressure, or an unexplained spike in your water bill.
2. The AC Condensate Line Clog
Your air conditioner doesn't just cool the air; it removes moisture from it. All that condensation drips into a pan and drains away via a small PVC pipe. During a hot July, your AC runs non-stop, producing gallons of water daily. If algae or debris clogs that drain line, the water will back up—often leaking directly through your ceiling or flooding your drywall.
- Pro Tip: Pour a cup of regular white vinegar down your AC condensate drain line once a month during the summer to keep algae from building up.
3. Sewer Line Backups (Thanks, Summer Trees)
Your trees are loving the summer sun, which means they are growing rapidly. To support that growth, their roots go searching for water. If there’s even a microscopic crack in your underground sewer pipe, tree roots will find it, break in, and cause a massive, messy backup.
- What to look for: Gurgling toilets, slow drains throughout the house, or a foul odor coming from your floor drains.
4. Overworked Water Heaters
You might think your water heater gets a break in July, but between extra loads of laundry from sweaty clothes, endless beach towels, and guests staying over, it’s often working double shifts. If your water heater is already on its last legs, the extra summer demand can cause it to fail completely.
Quick July Plumbing Checklist
To keep things flowing smoothly this month, take 10 minutes to do these quick checks:
- Outdoor Hoses - Disconnect them when not in use. Prevents constant pressure on the outdoor spigot, which can cause leaks.
- Sump Pump - Pour a bucket of water into the pit to make sure it triggers. Summer storms can cause sudden flooding; you want to ensure it works before the rain hits.
- Garbage Disposal - Avoid tossing fibrous summer foods (corn husks, watermelon rinds, celery) down the drain. These items easily clog the disposal and main kitchen drain.
