Water pressure is approximately 75 psi, therefore existing water pressure reducing valve is working at this time. Existing expansion tank on the domestic water side is not bleeding water out of the Schrader valve and there are no signs of any corrosion on the tank. 0 psi air pressure noted. Per request, pressurized this tank to 75 psi to match incoming water pressure. Supported tank/tubing with hanger iron. No warranty. Paid by card. Scheduled with to have Brad Garton out to provide a proposal for a sump pump installation with rigid discharge tubing and a check valve at exterior window well sump. Also per request, an electrical outlet would like to be installed at the same location.
