The water supply system adopts the full pressure type, which makes the water flow faster, wet water quickly and evenly, and avoid the mud and dust in the water, and the suspended sediment deposition in the pipe, causing the water pipe and the water spray holes. The unique design of the fountain, and the two ends of the water pipe to reserve a sewage outfall. Hemming tank adopts stainless steel or aluminum alloy materials, interface around by argon arc welding welding, without glass glue applicator, walls of water seepage pollution does not exist, the latter part of the use and other aging problems. For stainless steel or aluminum alloy curtain batten, so that in the future replacement of water curtain film is simple and convenient.
