This Saddle Valve Clamp is easy to install. As my Water Filter system is close to the washing machine, I drilled a small hole (2mm) into the washing machine inlet pipe and fitted the clamp onto the pipe and it works beautifully. Don't forget to turn off the washing machine water supply, drain the water that is already in the washing machine pipe, then drill the 2mm hole. Fit Saddle clamp and tighten. Connect all associated tubing and tighten nuts. Double check all connections!! Turn on water supply for the washing machine and check for leaks.
