Just purchased a Whirlpool low-boy water heater at Lowe`s and after installing the brass 3/4 cold and hot water fittings with pipe dope it leaked? Took it apart and tried teflon tape with the same result. Took the heater back and got another and after the install, still leaked. Both times at the female header. Has anyone else had this problem? Going to take this one back as well and try a different brand. Too bad we do not get paid for time wasted????:
