I bought this filter after reading the review and I'm glad I did. I got a 1/2" 3/4 compression fitting and teflon tape for the steps after deciding where I would mount the case. I measured how much I have. I also need to cut the copper tubing then I did screwed the thread in until it was tight after I applied the teflon tape and yes you use a bit more than most threads too but that's it after I lined up the copper tubing with the fitting and pushed it in until I felt it stopped, did the same on both sides, then I used the screws to attach it and the wall, done, I slowly turned on the water until it ran out completely, I also went to The kitchen also turns on the water, to to clean the air line and check the water pressure. That has also changed with the bathroom sink and tub. The pressure has never changed which is good and now I can finally tr water straight from the tap thanks to Ifilters inken do a good product
