Arrived to house, shut off water, drained the old 40 gallon well tank and then removed it from the house. Installed 40 gallon pressure tank with whole house 10†filter (20-1 microns). Turned water back on to house, calibrated pressure switch to proper 40 psi kick in and 60 psi shut off. Customer was shown how to change filter. Checked for leaks. It’s all working properly at this time. Customer is satisfied.
