When water hydraulic left me 2 root canal, an overflow, a lower water pipe, he put on the pipe three through the tap water and hot water pipes are connected, and in the upper and lower water pipe on the dark a ball, the ball is what is, Sheung Shui? If it is on the water off after the next hot water, if it is not Sheung Shui, then in what place did not see the location of the water valve he left the location of the water ah?
If the ball is in the upper and lower water pipes with three links to connect the "tap water and hot water through the three (under water with sun direction is up to the time of solar water), and the need to open the valve, full of water from the overflow at the water outflow, close the valve. Solar water heating is available. Use this method to add water.
The valve should be connected to the sink Xicai pool of hot water supply. Please ask the amount of your installation master.
If the three links above, indicating that the ball valve is a hot water switch. Then there should be a cold water pipe or a ball valve interface. It must have been less likely
