Is there a Tap Self Cutting Plumbing in Kit without the washing machine attachment?
I’m shooting in the dark here, but….. there is a kit that will self tap into a water line. These are called saddle taps. Saddle taps are made for copper tubing and are usually self piercing, self sealing, and will allow you to attach 1/4″ copper tubing . If you are trying to tap into PVC, there is a device called a Flo-Tap saddle that will do just that ….with the water on. I have only seen these for 1-1/2″ PVC and bigger….. they may make them, I just haven’t seen them. Hope this is what you were asking…. if not rephrase your question and I’m sure you’ll get a better response.
