Common Plumbing & HVAC Problems During the Summer
As temperatures rise during the summer, homeowners tend to focus on their cooling systems. However, your plumbing system is also more prone to certain issues during this season. Increased water usage, outdoor activities, and summer storms can lead to unexpected plumbing problems. At Riverway Plumbing, we want to help you stay ahead of these potential issues. Here are the most common plumbing problems to watch for during the summer months—and how to prevent them.
1. Clogged Shower and Tub Drains
Spending time outdoors often means bringing dirt, sand, and other debris back inside. When you wash off in the shower or tub, these particles can accumulate in your pipes, leading to slow drainage or even blockages. To prevent clogs, use a drain cover and rinse off outside when possible before heading into the shower.
2. A/C Not Cooling Properly
Few things are worse than a malfunctioning air conditioner during a heatwave. If your system isn’t cooling efficiently, it could be due to:
- Dirty air filters
- Low refrigerant (especially if your system is still using R-22)
- Frozen coils
- Thermostat issues
Replace filters monthly, keep the outdoor unit clear of debris, and schedule a professional tune-up in late spring or early summer.
3. Garbage Disposal Problems
Summer cookouts and holiday gatherings often result in more food scraps being tossed into the garbage disposal. Items like corn husks, fruit pits, and grease can clog the disposal and damage the blades. Avoid disposing of fibrous or hard items, and run cold water when using your garbage disposal.
4. Poor Indoor Air Quality
With windows closed and A/C running constantly, indoor air can get stuffy—especially with pollen, dust, and humidity in the mix.
Solutions:
- Install high-efficiency air filters (MERV 8–13)
- Consider a whole-house dehumidifier
- Keep your HVAC ducts clean and sealed

5. Leaky Faucets
Higher water usage during summer can wear out faucet components, leading to leaks. Even a slow drip can waste gallons of water over time. Regularly check for leaks and replace worn-out washers or seals to prevent excess water waste.
6. Washing Machine Hose Leaks and Clogs
More laundry due to sweaty clothes, beach towels, and outdoor activities puts extra stress on your washing machine. Heavy loads can lead to hose leaks or drain clogs. Inspect your washing machine hoses for wear and replace them every few years to avoid unexpected leaks.
7. Basement Flooding and Sump Pump Failure
Summer storms can bring heavy rains, increasing the risk of basement flooding. A malfunctioning sump pump can make matters worse. Test your sump pump regularly and ensure its discharge line is clear of debris.
8. Sewer Line Backups
Tree roots searching for water during dry spells can invade sewer lines, leading to backups. Signs of trouble include slow drains, gurgling sounds, and foul odors. Routine sewer inspections can help catch problems early before they turn into major blockages.
Warning signs:
- Gurgling drains
- Water backing up in sinks or tubs
- Sewage smell in the yard
9. Outdoor Hose Bibb Leaks
Outdoor faucets (hose bibbs) can develop leaks if they weren’t properly winterized. Inspect hose connections and replace washers or tighten fittings to prevent water waste.
10. Sprinkler and Irrigation System Issues
Lawn care increases in the summer, making sprinklers and irrigation systems more vulnerable to damage. Broken sprinkler heads from lawnmowers or foot traffic can cause leaks and water waste. Check for damaged components and ensure proper water flow.
