Those customer has a leak coming from what looks to be the tub in one of the bathrooms upstairs how ever in order to actually determine that is the cause I recommend opening up the ceiling to further investigate where the leak is coming from at this time the customer declined and said they just want to re-caulk the tub to see if that fixes it so there is no fix as of right now in addition to that the pressure reducing valve needs to be replaced at some point the pressure is at 80 psi I left a quote for that at this time. No work will be performed
