The wood floor is buckling around the main floor bathroom area. All bathroom fixtures on the main floor as well as the floor above were inspected for a potential leak. A couple minor issues were found with the bathroom, but nothing large enough to cause the damage. After further investigation, we found that the leak is coming from the waterline supplying the fridge. The line was disconnected and the shut off valve was bad too. Southside Plumbing replaced both the waterline and the shut off valve. The standing pressure was about 118 psi. Southside Plumbing also replaced the pressure regulator and set the pressure to 70 psi.
