Call for water leak in ceiling of first floor bathroom. Arrived and met with Ms. Janes. She showed me the water dripping from the ceiling. I inspected the upstairs bathroom and found water inside the vanity, and a drip hanging on to the elbow of half inch cpvc. When testing, I found a hairline crack along the elbow. Pressure regulating valve only about a year old. Water heater also just over a year. Pressure not tested as water was off, but I believe prv is functioning fine due to young age. Cut away broken section of cpvc. Installed new ball valve and pressurized system. No leaks or drips found. I also discussed the benefits of our maintenance membership program. I have also provided two estimates, one for a whole house water filtration system, and another for a Moen Flo automatic leak detection device. I have left contact information for reliable restoration, and recommend they be contacted to assess water damage to home.
