For this reason the residential RO units need a water storage tank to storage water. The RO tanks can delivery stable and constant water flow when the faucet is opened. The main pollutants might come from air or animals with use an open tank favors the use of a closed one.To avoid bad odors from diaphragm, all of our diaphragms are post-cured before assembly, to avoid these possibility of odors from the tank, our tanks are CE approved.Durability: valve core adopts the anti-high pressure material and installs additional sealing component, so the gas tightness is good, the pressure tank goes through 5 million times of life test of durability and discharge pressure before leaving the factory.Resistance of high voltage: each of the products goes through 1MPa experiment of resisting the voltage before leaving the factory, and it will not burst at the highest voltage of 2 MPa, Which ensures that the clients can use it at ease.Good quality: the outside tank made from FDA grade PP raw material, 12’’ * 14’’,The internal bladder are made by X2, AND R225.All the material are all accord with Food security level. The safety textOur pressure tank YZ-3.0A 20kg pressure text USA 3.0 water tankother Chinese factory 3.0 water tank15kg pressure text15kg pressure text China Taiwan 4.0 water tank 15kg pressure textresult:We can get the result by the picture, the American one, the one from Taiwan factory, split up barrel body below the 15kg pressure, the safety is worth discussing. other Chinese factory products are occurs with fracture solder under pressure in the 12kg, there are some problems in welding technology. our pressure tank with tearing phenomenon under the 20kg pressure , thus it can be seen our product with high quality.
