REPAIRING LEAKS IN STEAM
JACKETED KETTLE FITTINGS
Sight
Glass
If unit will not hold a vacuum the most likely cause is a
leak at one of the components threaded fittings, or within
the component itself.
There are two methods available for preventing leaks. The
advantage of the "Preferred Method" is that you eliminate
all potential leaks.
Preferred Method: Replace (using teflon tape)
Pressure Relief Valve, Pressure Guage, Water Level Probe
and Sight Glass.
Second Method: Remove and reinstall (using teflon
tape) all of the above four components. If unit continues
to lose vacuum replace components as per "Preferred
Method".
