Plumber Job - Monte Vista, WC, 7460

I have a solar water heating system on top of my roof. It is an evacuate glass heat pipe collector and the geyser. The connection between the heat pipes and the geyser requires "heat paste" (which must cover the end of the heat pipe that goes into the receptor in the geyser) to enhance the heat that must be transmitted from the heat pipe to the water in the geyser. The job entails to loosen the heat pipe ...retract it from the geyser, cover the end of the heat pipe with heat paste and push it back into the geyser.
