It is probably on a PEX line and you will need a crimping tool to do it right. They have the valves and tools at HD and Lowes or you might save some money by getting them at Amazon. In a pinch I have used small diameter screw-type radiator clamps by they are not the best and often will leak.I have a 139 FF that has the two low point drains in the floor below the sink. One of them is leaking all the time. Anyone know where I could buy a new one?
