San Diego's hard water cakes up cartridges, seats, and aerators faster than almost anywhere else in California. Whether it's a shower valve in a La Jolla condo, a faucet in a North Park bungalow, or a running toilet in Chula Vista, the real fix is usually a clean cartridge swap plus (eventually) a softener.
Common questions
Why won't my shut-off turn?+
Old multi-turn valves corrode internally. Once they seize, forcing them usually snaps the stem. We replace with quarter-turn valves that won't seize.
How long does it take?+
A standard angle stop swap is 20 to 40 minutes per valve. Main shut-off replacement is 1 to 2 hours.
Should I replace all my angle stops at once?+
If they are original and over 15 years old, yes. It is cheaper than paying for one emergency call later.
Why do my faucet cartridges keep failing?+
Almost always hard-water scale, not defective cartridges. San Diego water is 15+ grains per gallon and cakes up cartridges fast. A softener extends fixture life dramatically.
Can you work in condos and high-rises Downtown or in Mission Valley?+
Yes. We do fixture work in condos across Downtown, Little Italy, Mission Valley, and Coronado. We coordinate any building water shut-off with property management if needed.
