Arrived on site , tenet was onsite, he let me inside the home and I spoke to him about the issues he’s been having. Checked garage and found access panel with shutoff and prv in wall. Tested pressure to home it was about 89-90psi meaning the prv has failed. Wrote up 2 solutions however was unable to reach homeowner, emailed pictures and invoice. Called customer and spoke with him about pricing. He did let me know he is going to call out a different company today to get a quote. I did explain our apples to apples price match. Also explained that if he calls someone out, it needs to be a licensed plumber not a handyman. As only plumbers are allowed to work on any type of plumbing in the state of Texas and carry insurance.
