That includes pressure reducing valves on the main line, angle stops under sinks and toilets, hose bibs, water heater valves, and the in-line valves that let you isolate one part of the house without shutting off everything.

Most homes do best between about 50 and 70 PSI. Above 80 PSI, a pressure reducing valve should be installed or replaced.
Typically 10 to 15 years. Hard water and high street pressure can shorten that.
Old multi-turn stops often seize. If one fails to close during an emergency or snaps when turned, a small repair becomes a flood. Quarter-turn valves avoid that.
It is a warning sign. It can mean high pressure, excessive temperature, or a worn valve, and it should be checked promptly.
Simple screw-on spigots are a manageable DIY job. Bibs soldered into copper or set inside a wall are better left to a plumber to avoid damaging the line.
We start by measuring your static water pressure with a gauge at a hose bib. Readings above about 80 PSI point to a failing or missing pressure reducing valve, which is one of the most common causes of leaking fixtures, noisy pipes, and short-lived water heaters. Low readings send us looking for a partly closed main, a failing regulator, or a restriction in the line.
For individual valves, we check whether they open and close fully and seal without dripping. Older multi-turn stops often seize from mineral buildup and break when forced, so we usually replace them with quarter-turn valves that are easier to operate in a hurry. You get a written price first, and we test each replaced valve under pressure before we leave.
During a remodel or repipe we also add isolation valves at sensible points, such as each bathroom group or the irrigation tap, so future repairs only interrupt water to the area being worked on. Every valve we install is labeled where it is not obvious, which saves time for you and anyone who works on the house later.
San Diego County water is hard, and minerals build up inside valves until they stick, weep, or refuse to close. Many neighborhoods built on hillsides also receive higher street pressure than a home's plumbing is designed for, which makes a working pressure regulator important, and those regulators typically wear out after a decade or so.
Valve services we offer:
With the right pressure and working valves, fixtures stop dripping, appliances last longer, and you can shut off water to a single sink or toilet in seconds when something goes wrong. Correct pressure also protects washing machine hoses and water heater tanks, two of the most common sources of sudden household leaks.
Letting high pressure or bad valves go has a real cost. Excess pressure strains every connection in the house, a seized stop means shutting off the whole home for a small repair, and a leaking relief valve can be a sign the water heater is working under unsafe conditions.
To get your pressure checked and your valves working right, call (619) 349-4189 or schedule online.
