Frequently Asked Questions
Why won't my shower get hot enough in my Cornelius home?
The most common causes are a worn cartridge restricting the hot side, an anti-scald limiter set too conservatively, or a failing mixing valve. In Cornelius's 1950s–1970s older core, 1990s–2000s newer development construction, Moen and Delta cartridge replacement in 1980s–2000s Cornelius shower valves is typically the culprit. We diagnose before replacing anything.
How long does shower valve repair take in Cornelius?
A cartridge replacement takes 45–60 minutes. A full valve body replacement is typically 2–3 hours. We give you a time estimate before starting.
Should I repair or replace my shower valve in Cornelius?
If only the cartridge is worn, repair is the right call. If the valve body is cracked, corroded, or discontinued with no parts available, replacement makes more sense. We tell you honestly which situation you're in.
