Ventilation & Trap Fixes
Plumbing issues you are facing:
- Drains gurgle when water runs or toilets flush
- Slow drainage despite no visible clogs
- Sewer gas odors coming from drains intermittently
- Water siphoning out of traps, leaving them dry
- Bubbling sounds from fixtures when others drain
- Multiple fixtures affected when one drains
- Recently added fixture draining poorly
- Failed inspection due to venting issues
What D&H PLUMBERS fixes:
- Diagnose venting problems causing siphoning or gurgling
- Install proper vent pipes to atmosphere where needed
- Add air admittance valves (AAVs) where traditional venting isn’t feasible
- Correct trap arm slopes and distances to comply with code
- Verify proper trap seal depth (2-4 inches)
- Connect island sinks and remote fixtures with appropriate venting
- Test drainage flow and verify gurgling eliminated
- Ensure all work meets local plumbing codes
