How to Fix a Water Main Leak in Rohnert Park
Fixing a water main leak requires shutting off the water at the main valve, calling a licensed plumber, and determining if it's on your property or the city's side. Only attempt a temporary clamp if safe.
Immediate Steps to Take for a Water Main Leak in Rohnert Park
If you discover a water main leak at your Rohnert Park home, act quickly to minimize damage. Here’s what to do first:
- Shut off the main water valve. Locate the valve near your water meter—usually at the front of your property. Turn it clockwise to stop the flow. If you can't find it, call our team for help.
- Turn off your water heater. To prevent damage, switch off the power (gas or electric) to your water heater once the water is off.
- Call a licensed plumber immediately. Water main leaks require professional repair. CNTRLine Plumbing offers 24/7 emergency service—call (707) 308-5599. We serve Rohnert Park, Cotati, Penngrove, Santa Rosa, Petaluma, Windsor, Novato, and San Rafael.
- Check if the leak is on your side or the city's. Look at your water meter. If the leak is before the meter, contact the City of Rohnert Park Water Department. If after, it's your responsibility—we can help.
- Document the leak. Take photos and notes for your insurance claim. Most policies cover sudden water damage, but check with your provider.
Our team arrives with same-day service on most calls. We're licensed, bonded, and insured (CSLB #1036920), so you're protected.
Temporary Fixes for a Water Main Leak: What You Can Try
While you wait for a plumber, you may attempt a temporary fix—but only if it's safe. Here are steps for a DIY stopgap:
- Gather supplies. You'll need a pipe clamp or epoxy putty from Ace Hardware Rohnert Park or Home Depot Rohnert Park. Ensure it's rated for water main pressure.
- Dry the pipe. Use a rag to wipe the area around the leak. The clamp or epoxy needs a clean, dry surface to seal.
- Apply the clamp or epoxy. Follow the product instructions. For a clamp, tighten it over a rubber gasket. For epoxy, knead and press it into the crack.
- Test the repair. Slowly turn the water back on and check for drips. If it holds, it's a temporary fix—but call a plumber for a permanent solution.
Remember, these fixes are not reliable long-term. Water main leaks can worsen, leading to foundation damage or sinkholes. Our team at CNTRLine Plumbing recommends professional repair.
