Frequently Asked Questions
How do I know the flange joint is leaking?
A ticking or blowing note at the joint and soot tracks at the flange point to a failed joint. Soak the hardware and renew the flange gasket to seal it.
Any tips for the seized joint hardware?
Soak the flange bolts in penetrating oil first and expect them tight, then renew the flange gasket so the repaired joint seals.
