Brass nipple goint to valve is still dripping!
Trying to hook up cold water supply to a hot water tank. I am using a brass shut off valve. I need to screw a brass nipple between the valve and the flexible hose that goes to the tank. The valve has a female opening and so does the flexible hose. I have put teflen tape on each end of the nipple but am having a slight drip on the end that goes into the valve. I have taken it apart twice, cleaned off the old tape from all of the threads and rewrapped the tape. I have wrapped the tape around three times and overlapped it while working from the open end towards the center of the nipple. I AM STILL HAVING A PROBLEM WITH A SMALL DRIP! HELP.
Thanks
