I spent 5 years of solar energy, the aging of the pipe, the water temperature in the summer maximum temperature of only 70 degrees, the highest winter temperature of more than and 50 degrees. Would like to replace. But the old pipe rubber ring are aging, stiff, and vacuum tube and water tank are mixed together, the pipe can not move, do not get down, what is the good way to put the old pipe down?
Oh, I'll teach you something. First of all, find a medical syringe, full of lubricant (detergent dilution, soap, water, etc.), the dust ring down
(no longer on the two people together) so that the vacuum tube down (pay attention to the vacuum tube under the needle oh). Vacuum tube can not be changed, the scale of the clear inside the line. Try it, ha ha
The lubricant into the vacuum tube and the water tank in the gap (must be shot in the bottom of the sealing ring, around the shooting). Then put on rubber gloves for the labor (anti vacuum tube rupture hands turn firm) a vacuum tube, go up
