For those customer, the water pressure was low whenever the appliances were being used and or the rest of the house what I recommended is to replace the pressure reducing valve with a stronger one and adjust it to 65 pounds we did that in completed the task to add to the vacuum breakers on the exterior hose bibs were failed and I recommended replacing those as well so that is exactly what we did replace both vacuum breakers. In addition to that Moen cartridge for the shower needed to be replaced in the upstairs guest hallway once replaced there’s no leak went back with clear caulk for the trim and the customer is all set.
