The lifetime usage for a bidet spray depends on a number of factors, including the quality of the bidet spray, how often it is used, and how well it is maintained. However, most bidet sprays are designed to last for several years.
We recommend using a T-adapter valve to supply water to the Bidet when in use and shut it off when not in use. This prevents long time pressure build up in the hose and bidet spray, therefore increasing the longevity of the bidet system.
