Find these before you need them
- The main house water shutoff, and whether it turns.
- The meter box and the tool its valve needs.
- The fixture valves under every sink and behind every toilet.
- The cold supply valve and gas control on the water heater.
- The outside sewer cleanout.
- The gas meter, so you can tell responders where it is.
Weak points to inspect
| Item | What to look for | Why it matters |
|---|---|---|
| Washing machine hoses | Cracks, bulges, rubber hoses | A split hose can flood a room quickly |
| Toilet and sink supply lines | Corrosion, kinks, drips at the nut | Common source of sudden leaks |
| Water heater | Rust at the base, drips, damp floor, seismic strap present | Tanks fail from the bottom; California requires seismic strapping |
| Pressure regulator | Banging pipes, very strong flow, dripping relief valve | High pressure stresses everything |
| Trees near the sewer line | Large trees between the house and street | Roots are a leading cause of lateral blockages in older neighborhoods |
A one-afternoon plan
Walk and label
Find every shutoff and put a tag on the main valve so anyone in the house can find it.
Test the main
Turn the main off and back on. If it is stiff or leaks, plan a replacement.
Swap old hoses
Replace rubber washer hoses and worn supply lines with braided ones.
Check the water heater
Look for rust and drips, confirm it is strapped, and read the label for its age.
Build a small kit
Meter key or adjustable wrench, flashlight, towels, buckets, gloves and a phone number list.
Save the right numbers
SoCalGas, the City of Anaheim water utility, your insurer, and a licensed plumber you have already checked at cslb.ca.gov.
Habits that prevent emergencies
Keep grease, wipes and paper towels out of drains. In homes with old clay or cast-iron laterals, those are the materials that turn a few roots into a blockage.
Pay attention to small changes: a slow drain that gets slower, a water bill that creeps up, a faint sound of running water at night. Those early signs are much cheaper and easier to deal with than the emergency they turn into.
Questions for a routine plumber visit
- Can you check my water pressure and regulator?
- Is my main shutoff worth replacing with a ball valve?
- Would a sewer camera inspection make sense given my house's age?
- Is my water heater strapped and vented correctly?
Common questions
How often should washing machine hoses be replaced?
Check them regularly and replace them at the first sign of cracking or bulging. The appliance manual may give a recommended interval.
Is a sewer camera inspection worth it without a problem?
In older homes with mature trees, some owners find it useful before a sale, a purchase or after repeated slow drains.
Should I keep a plumber's number saved?
Yes. Check the license at cslb.ca.gov in advance so you are not doing it during an emergency.
