Preparing Your Home's Plumbing for Southern California's Rainy Season

As fall and winter approach, Southern California homeowners know that the rainy season can bring surprising challenges. While our region is known for sunny skies, even a few days of heavy rain can cause plumbing headaches, especially in neighborhoods like Simi Valley, Thousand Oaks, Moorpark, and Ventura. At Highsmith & Daughters Plumbing Inc, we want to share practical tips and insights to help you prepare your home's plumbing for the rainy season, protect your investment, and avoid expensive emergency repairs.


Why Rainy Season Prep is Vital for Southern California Homes


Southern California’s unique climate means months of dry weather followed by sudden downpours. This weather pattern can overwhelm residential plumbing systems, especially if preventive maintenance isn’t performed. Local soils and landscaping practices can lead to drainage issues that affect plumbing both inside and outside your home. Whether you live in Agoura Hills, Calabasas, Westlake Village, or Simi Valley, preparing your home's plumbing for wet weather is crucial to prevent water damage and costly plumbing emergencies.


Inspect and Clear Outdoor Drains and Gutters


One of the most common causes of plumbing problems during the rainy season is clogged outdoor drains and gutters. When debris builds up, rainwater has nowhere to go, leading to pooling around your home's foundation and potential leaks inside.


How to get ready:


  • Clear leaves, dirt, and debris from gutters and downspouts.
  • Ensure all outdoor drains (including those in patios and driveways) are free-flowing.
  • Check the grading around your home to make sure water flows away from the foundation.


If you’re unsure about your drainage system’s condition, or if you notice standing water after a rain, it’s a good idea to have a local plumber do an inspection.


Check for Leaks and Address Them Early


Rainy weather can reveal existing leaks in your plumbing system. Small leaks in pipes, water heaters, or fixtures can quickly become bigger problems when strained by extra water volume.


Warning signs of hidden leaks include:


  • Unexplained increases in your water bill
  • Damp spots on walls, ceilings, or floors
  • Persistent moldy or musty odors
  • Sounds of running water when fixtures are off


At Highsmith & Daughters Plumbing Inc, we use modern leak detection tools to quickly identify and repair leaks, protecting your home from water damage.


Maintain and Test Your Sump Pump


While sump pumps are not as common in Southern California as in other regions, many homes in low-lying or flood-prone areas of Moorpark, Camarillo, or Chatsworth rely on them. If you have a sump pump, ensure it’s ready for action:


  • Test the sump pump before the rainy season by pouring water into the pit and ensuring it activates.
  • Clean the pit and remove debris that could block the pump intake.
  • Confirm the discharge line is clear and directs water away from your foundation.


If your sump pump has any issues, schedule a professional inspection before the heavy rains arrive.


Keep Sewer and Drain Lines Clear


Heavy rainfall can overload municipal sewer and stormwater systems, which may lead to backups into residential properties. Regular drain cleaning and maintenance can keep your pipes flowing and reduce the risk of a messy backup.


Preventative steps:


  • Avoid pouring grease, food waste, or non-flushable items down drains.
  • Schedule annual drain cleaning, especially if your property has mature trees (roots can invade pipes).
  • Watch for slow drains, gurgling sounds, or bad odors—these could indicate developing blockages.
