3/25/24 Sent out today to Rick and Mary’s in regards to a shower with no flow. Upon arrival I was greeted by the two and went over the purpose of the visit and answered any immediate questions they had. Rick led me to the master bathroom explaining they have already cleared the shower head and attempted a shower rebuild and wants to know what needs to be done next. I went over how they did exactly what I would have started with. I then explained the next step would be replacing the shower valve however I wanted to run vital test to see if we could determine why this happened in the first place.
