“Had a similar shut off valve that was leaking from the stem... The screws were identical... Five minutes to replace the existing valve body without having to sweat new elbows onto the copper supply pipes!”
“Had to replace old valve (Leaking from center stem)... From there was able to take off old valve housing and O-rings... YouTube has videos on replacement of old valve to new valve. Good Luck!”
“Perfect fit. For years I have been leaving it on because it leaked when I shut off. Then I realized only 2 screws to remove and I had it replaced in 5 minutes.”
