ThermOmegaTech® recommends changing the GURU® Plug every 18-24 months. The characteristic tendency of the
GURU® Plug’s actuator is to lose a small amount of stroke as it ages beyond one year. This stroke loss causes the
release temperature and the manual reset temperature to creep upward. While this is a “safe” tendency for freeze
protection, the upward creep can eventually cause nuisance dumping.
The GURU® Plug’s colored cap serves as a visual indicator of the year it was built. Five colors rotate, each associated
with a year.
View the cap color chart below
. The month and year that the valve was manufactured is also laser marked
on the top of each cap.
NOTE: Both the Hex Nut and Valve Cartridge MUST be changed out.
We offer a rebuild program that allows you to return your old Guru Plugs to be refurbished for a discounted price. For
