I’m here to figure out why the pressure in the upstairs bathroom is really low. After doing some diagnostic and inspection of the homes plumbing everything looks to be in great condition. He had a new water heater a little while back after his original one failed.and all the faucets have been replaced within the last 7 to 8 years. The only stuff in the house that it was built was piping behind drywall. I’m certain that the reason he’s I can hot water is cause his shower valve behind the wall has failed causing hot water to not be able to flow through properly. I let him know how we would fix that and what it would cost, he asked how long it would takebecause he has plans around 3 PM today. I let him know from start to finish. It takes roughly 1 1/2 to 2 hours if everything goes smoothly.
