Client called about leaking water softener we installed 3 years ago. It has a 5 year warranty. Tevh went out water pressure is good 65 psi, expansion tank is still good functioning normally. Tech found the leak from the plastic compression water connectors. Tech removed connector and installed brasses connections. Tested for leaks no more leaks found client is happy. Tech noted that the main water shut off is in very rough shape and appears to have been leaking from time to time. Tech has informed client and quoted to replace it.
