Self Piercing Saddle Valve Installation Instructions

  • Choose a location as close to the RO unit as possible.
  • Make sure the water supply is OFF.
  • Back up the piercing pin all the way by turning the handle counterclockwise. It should be retracted slightly past the rubber gasket.
  • Position the valve over the pipe and turn the loose clamp piece appropriately to fit the shape of your pipe.
  • Firmly snug the valve to the pipe by turning the screw/bolt. This should be done by hand to avoid over tightening.
  • Slide compression nut on RO tube.
  • Slide on compression sleeve. Note that the sleeve is narrower on one end. Narrow end should be away from valve.
  • Insert brass insert into tubing end.
  • Tighten compression nut to valve to attach tubing. Do not over tighten.
  • Slowly turn valve handle clockwise to pierce pipe. Turn it all the way. This is the "OFF" position.
  • Back the valve handle out to open.
  • Turn on water supply and check for leaks.

  • Broke my copper pipe By Sam on 1/17/2016

    Brs is awesome and that's why I can't give a bad review for what may have been my fault. Anyway I pierced a 3/4 copper pipe and it caused a leak, which resulted in having to replaced a section of pipe. I wouldn't up just adding an a spicket to the pipe and used the garden hose adapter instead.
  • Good a quality By Kevin v on 4/17/2015

    Didn't end up using but quality was dead on and appeared to serve its purpose
  • Worked in the end By Timm on 2/17/2015

    I needed a quick solution to get up and running and this worked. The directions, at least in my opinion, were less than desirable. I used a youtube video to watch how it worked and was able to install. In the end I went through two of these because of user error, not product fault.
  • Too Easy! By pbhonl on 7/15/2013

    Even though I had a quick-snap adapter on my laundry room faucet, I grew tired of having to unhook it when I wanted to use the laundry room sink.

    I was skeptical that I would get enough pressure using a saddle valve.

    Installing it was easy; didn’t see a drop of water leak and I get the same pressure as when it was connected to the faucet.
  • Simple to Install By Den on 5/7/2013

    Used this to connect my RO/DI to an existing 3/4" water line. Installation was simple and so far works as expected
  • Excellent Product By Adam on 4/29/2013

    Glad I purchased this to install my RO/DI under my sink.
  • Works great! By Michael on 3/12/2013

    Used this valve to attach to my RO/DI Unit that I bought, very simple to use and easy to attach the hose with the compression fitting.
  • Perfect! By The Reef Spot on 3/2/2013

    Bought this to replace the laundry tub adapter. Now I can keep my water reservoirs topped off, and still use my sink. No more unscrewing an adapter every time i just want to rinse something off!
  • great product By nguyen on 2/29/2012

    just what i needed for the ro unit. no leak
  • Better than hooking up to faucet By Leland on 10/10/2011

    I used this to locate my RO/DI unit closer to my resivour in my basement. Copperpipe is right over head,so it made locating the unit easy, and I dont have to attach it to my sink faucet anymore.
  • Will Work On Input Or Output By cm11599ps on 11/16/2010

    I have my RO unit installed in my boiler room so there's no drain in there. I ended up running a piece of 1" PVC from my boiler room out into my yard into a well I dug for my gutter downspouts. I then attached this saddle valve to the 1" PVC to run the RO waste into that well. Works like a charm.

    Being that my PVC is thicker then the copper tubing this is really meant for I had some extra steps. I attached the saddle valve to my PVC and pierced the PVC. I then completely removed the saddle valve and used a screw to help make the hole a little bit bigger. I then took the screw out and reattached the saddle valve, hooked the RO to it and called it a day. Works great.

    The valve is really meant as an input for connecting your RO unit to your water supply line but I figured it it can handle the 60psi of a typical house then it could handle whatever pressure my waste water was which I"m sure isn't too much at all.
  • great performance and quality!! By Melad 360 on 11/4/2010

    i got this to attach my RO system to the copper piping in our house because the humidifier line didnt have enough pressure to make the system work properly. i shut off the water, attached the valve, and BINGO! not a single drop of water was spilled during, or after attachment. the unit is built with high quality components, and is very easy to use. just screw to tighten it onto the piping, screw the needle, unscrew, and done. i would highly recommend this to anyone wanting to attach their RO system to copper pipes without expensive Tees, valves, diverters, etc that you would have to get instead.Pr
