Product review (5 stars): Great kit but......
This kit works well. After reading some of the negative reviews I will offer solutions . 1) learn how to use ferrells before doing the job. There is some knowledge necessary . ( do not push Ferrell and the tubing in all the way ... The tube end needs some room as you tighten it. 2) the piercing valve will only put a 1/32 " hole in the copper main. Once you have installed the saddle and pieced the copper., back out the piecing needle and remove it temporarily. Get your electric drill out and drill out the hole with a 3/16" bit . Reinstall the needle and valve bonnet . This will allow full flow to your refrigerator water in door option. That's it..... Works great ....no leaks and plenty of flow .
