The main water inlet should be lined with the normal diameter of the control valves. The ball valve should be open when in use. If two valves are installed in the same pool, the two valves should be kept in the same horizontal plane. Before installation, clean the debris in the pipes in case of blockage. If the water quality is not good, the valves must be properly maintained.
