Pride Plumbing came out and installed a new HydraPro HPTET2 2-gallon thermal expansion tank at a 40-gallon electric A.O. Smith lowboy water heater using new PEX piping and fittings. We also provided cost estimates to 1) replace the water heater with a new 40-gallon electric lowboy model; and 2) replace a faulty pressure reducing valve (PRV) at the water meter (attaching it to the existing black roll outside main water supply line with new PEX piping and fittings and adding a ball water shutoff valve).
