Product review (5 stars): DIY and S A V E
I drilled into the PVC pipe after I turned water supply off. Easy to attach, had to run the line from my basement 10' to the wall and up through the kitchen floor, under the back of our refrigerator, put an external Wondar in line filter against the back kitchen wall, cut plastic line, pushed tubing in the In-side and extra tube from Out put side of filter to fridge. I left the extra tubing coiled so I could move the refrigerator if needed. Works NO leaks when turned on.
