Summer is one of Tacoma’s busiest plumbing seasons. With hotter weather, heavier household water use, and added stress on city infrastructure, sewer backups become surprisingly common this time of year. A backup can bring your home to a halt—and fast action is essential to prevent serious damage.
If you’re dealing with (or hoping to avoid) a sewer backup in Tacoma this summer, here’s what causes it and what you should do right away.
Why Sewer Backups Happen More Often in Summer
1. Higher Household Water Usage
Summer means more showers, laundry loads, lawn watering, dishwashing, and guests—all of which put additional strain on your plumbing. When too much water enters the system at once, older or partially blocked sewer lines can quickly become overwhelmed.
2. Tree Root Intrusion Accelerates in Warm Weather
Tacoma’s mature neighborhoods mean lots of older trees—and their roots grow aggressively in summer. Roots naturally move toward moisture and can break into older sewer lines through tiny cracks or joints, eventually blocking or collapsing the pipe.
3. Tacoma’s Aging Sewer Infrastructure
Many sewer lines in our area were installed decades ago. Aging clay or cast iron pipes are more vulnerable to cracking, shifting, or collapsing under summer ground movement. When a section fails, wastewater has nowhere to go but back into your home.
4. Stormwater Overload During Summer Downpours
While Tacoma summers are relatively dry, sudden storms still happen. Intense rain can overwhelm sewer systems, especially combined lines. When city lines back up, homes connected to them often feel the impact.
5. Grease and Debris Buildup From the Rest of the Year
All the oils, wipes, food waste, and debris that have accumulated over months can solidify in warm temperatures, restricting flow. Summer is often when small blockages turn into big backups.
Early Warning Signs of a Sewer Backup
- Gurgling or bubbling drains
- Slow draining in multiple fixtures
- Sewage odors inside or outside the home
- Water backing up in tubs or showers when toilets flush
- Wet patches or sunken spots in the yard
What to Do Immediately if Your Sewer Backs Up
1. Stop using water in the home
Running water will only worsen the backup. Avoid flushing toilets, running appliances, or using sinks.
2. Keep people and pets away from affected areas
Sewage contains bacteria and contaminants that require proper handling and sanitation.
3. Do not attempt chemical drain cleaners
These can worsen blockages or damage older sewer lines—especially common in Tacoma homes.
4. Call a licensed plumber immediately
Backups can escalate fast. Rooter-Man Plumbing of Tacoma can diagnose the cause, clear the line safely, and prevent future issues.
5. If flooding occurs, document damage for insurance
