Home solar control is bad, I would like to ask how to change their own, by the way, where to buy a vacuum tube, I was in Nanjing,Thank you
Strenuous?Looking for a solar energy for a professional maintenance can not it?No more than 100 yuan why bother yourself!!
You go to buy the solar energy to buy a bar, with soap and water wet pipe inserted into the solar bucket on the line, the vacuum tube twenty or thirty dollars a very easy!
In hot water, take out the tube, the inside of the sealing ring look bad not bad
