Existing 5 gallon pressure tank had a pinhole at the bottom of the tank because the galvanized strapping ate through it over time, tank was also water logged because the water pressure in the home was 120 psi. Installed new 5 gallon expansion tank with plastic strapping and 3/4” pressure reducing valve with whole home pressure gauge. Both of these items are working as they should at this time with no issues. Still wrote estimate to replace the water heater because the existing heater is over 20 years old.
