Monsoon Season Plumbing Prep for Tempe Homeowners
Why Monsoon Season Is Different
Tempe's plumbing and drainage systems are built for a mostly dry climate, which means monsoon season (roughly July through September) can overwhelm systems that go months without heavy rain. Sudden, intense downpours can expose weaknesses in aging sewer lines and drainage systems that stay hidden the rest of the year.
Pre-Monsoon Checklist
- Clear debris from outdoor drains and gutters before the season starts
- Check that your yard grades away from your home's foundation
- Have a sewer camera inspection if your home has an older clay or cast-iron sewer line
- Test your sump pump if your home has one
- Know the location of your main water shutoff valve
During a Storm
If you notice water backing up into sinks, tubs, or floor drains during or after heavy rain, that's a sign your sewer line may be struggling with the sudden volume, potentially compounded by root intrusion or existing damage. Avoid running additional water down drains until the backup clears.
After the Storm
Once the rain clears, it's worth checking for any new slow drains, unusual odors, or standing water near your foundation — early signs of an issue that monsoon season may have exposed or worsened.
