- Globe valves – common in older buildings; allow precise flow control
- Spring/swing check valves – backflow prevention for vertical and horizontal runs
- Angle stops – under-sink shut-off for quick isolation.
- PRVs (pressure-reducing valves) – regulate high water pressure and extend pipe life.
Every valve tells a story. We’re fluent in all of them.
FAQ Shut-Off Valve Services in San Diego
Q1: . How do I know if my shut-off valve is going bad?
If the valve is hard to turn or doesn’t stop water flow entirely, it’s likely time for a repair or replacement. Corrosion around the handle is another red flag.
Q2: Why is my shut-off valve leaking?
Most leaks occur from worn seals, corrosion, or aging internal components. Over time, valves lose their ability to seal properly.
Q3: Should I repair or replace my shut-off valve?
In most cases, replacement is the best option because modern ball valves last longer and operate more reliably.
Q4: How long does shut-off valve replacement take?
Most valve repairs or replacements take 45 minutes.
Q5: Are old angle stops safe?
Older multi-turn valves often fail due to corrosion. Replacing them with ball valves greatly improves reliability.
Q6: Do you replace water heater shut-off valves?
Yes — we replace leaking or stuck water heater valves with durable, code-approved ball valves.
Q7: Why won’t my shut-off valve turn?
Age, mineral buildup, and corrosion can seize the internal components. Forcing it may cause a leak.
Q8: Do you offer free estimates for valve repair?
Yes — American Plumbing Co. provides free, upfront estimates with no hidden fees.
Q9 . What kind of shut-off valves do you replace?
We replace ball valves, globe valves, angle stops, PRVs, and even gas shut-off valves for residential setups.

Yes. We have emergency repair service across San Diego and can usually respond within hours, depending on your location.
Q11: Can I fix a shut-off valve myself?
An improperly installed water shut-off valve can cause a serious leak.
