We had recently made many repairs, added valves and piping for the existing rinse station. I arrived today because the client states that the hot and cold piping are backwards. After a through evaluation, I discovered that the client is correct and a minor repipe is needed to correctly repair issue this issue. Shut system off. Cut out piping below the ball valve which turn the system on. Crossover over piping to the correct risers. Secured my connections and turned the system back on to check for leaks. There are no leaks at this time. *Client is aware that today service is voided if the client does not properly winterize the shower before the winter months.
