The Local Water District
North Coast County Water District serves most of Pacifica, San Pedro Valley Park and part of San Bruno across 13 square miles, and also supplies recycled water and fire protection water. Check your bill and the district’s water quality report for the current supply mix. Notices come from the district. Your side starts at the meter and runs through the whole house.
Fog, Salt Air and Constant Moisture
Fog and salt air corrode hose bibs, valves, supply stops and heater bases, and damp crawlspaces rot pipe supports. Turn each shutoff yearly and swap braided lines about every ten years.
Cliffside and Hillside Lots
Steep lots and eroding bluffs shift soil around buried lines. Watch for new cracks, gaps around pipes and wet ground below a slope.
Homes From the 1950s to the 1970s
Many Pacifica homes were built in the postwar decades and have galvanized supply, cast iron drains and clay laterals. A written report before you buy or renovate tells you what to keep and what to replace.
Bracing Your Water Heater
A tank heater should be strapped to the wall studs in two places. Use flexible connectors on both the water and gas sides and keep a wrench near the gas meter. An automatic gas shutoff valve is worth asking a plumber about.
Meter Test for Hidden Leaks
A leak under the floor can run for weeks before anything shows. Check irrigation lines too, since they leak just as quietly. Finding the exact spot keeps the repair small. Emergency plumbing is there for leaks that cannot wait.
Drains and Roots
A camera inspection shows the cause of slow drains. Keep the cleanout cap accessible and clear of landscaping. Simple clogs call for drain cleaning; a cracked or collapsed line calls for sewer line repair.
Why Fixtures Crust Over
White crust on faucets and a heater that rumbles are signs of scale. Soak aerators and showerheads in vinegar every few months. If the unit is old, water heater repair can tell whether a flush will help.

Quick Checks Before You Call a Plumber in Pacifica
Replace worn toilet parts as a set. A flapper, a fill valve and the flush handle assembly cost little and often wear out together after about ten years. If a toilet rocks, the closet bolts or the wax ring may be loose, and ignoring it can rot the subfloor. A visit that addresses all of these at once is usually more economical than several small calls.
If you have a water softener, check the salt level monthly and listen to make sure it cycles. A bridge of hardened salt in the tank can stop it working even when the tank looks full. Test the water with a hardness strip every few months. If the water feels hard after regeneration, the resin or the valve may need service, and a plumber can test and adjust the unit.
Look for the signs of a hidden leak behind a wall: a stain that grows, a bubbled paint patch, a musty smell, a warm spot on the floor or the faint sound of water at night. Read the meter, and if it moves, close the main. A plumber can use acoustic and thermal tools to find the leak without opening large sections of drywall, which keeps repair costs and mess down.
Learn the signs of a failing water heater: rust-colored hot water, a rumbling or popping sound, water pooling at the base, a pilot that goes out or a tank that no longer keeps up. Any of these deserves attention. If you ever smell gas, leave the house and call the gas utility or 911. Otherwise, shut off power or gas and the supply, then call a plumber to assess the unit.
Make sure dishwasher drains have a high loop or an air gap. Without one, dirty sink water can flow back into the dishwasher, and the unit may drain slowly. Check the hose for kinks and clean the air gap cap if there is one. If the sink backs up when the dishwasher runs, mention it, because the garbage disposal knockout plug may also be left in place.
