Upon arrival of we tested the ,aster bathroom shower tomorrow test if it was turning on. Homeowner reported it didn’t turn on this morning. When we tested the shower it worked as it should. Both shower valves and bother shower systems shower head, body sprayer, and side sprayer worked appropriately. Temperature adjustment worked as it should as well. We took apart the handle and tighten everything associated with it re assembled and tested it again. Everything is operating as intended at this time.
