devildog1986 Posted August 2, 2016 Share Posted August 2, 2016 Does anyone on here know if I can tap my RODI to pex pipe? I don't want to pick up the tap at lowes if it won't work. Thanks. I've never worked with Pex pipe before Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
Timfish Posted August 2, 2016 Share Posted August 2, 2016 If you are talking about supply to your RO/DI filter you should be able to use standard plumbing bushings to connect them. If you are talking about goinf from the output to a makeup tank, ATO or display tank you need to make sure you only use PVC fittings, not metal.

Isaac Posted August 2, 2016 Share Posted August 2, 2016 Theres no real good way to "tap" pex. You need to insert a tee, then install a typical 3/8 "sink" valve on it. tee: http://thd.co/2aK9P2Q fitting to valve: http://thd.co/2aK9JZf valve: http://thd.co/2aK9Sfe 3/8->1/4 compression adapter: http://thd.co/2aKamC2 fitting&valve are available as one piece ( http://thd.co/2aKbeGJ )... but its easier to swap out a valve later on if you go threaded like this. This assumed you have the proper pex compression collars and tools. There are slip-fit "sharkbite" versions of the above, but I've never trusted those compared to the compression fit ones. If you go the slip fit route, I'd be paranoid enough to get 2 of each fitting and put them in a bag sitting next to the valve in the event they start leaking. many plumbers love this platform, but its seriously just an o-ring away from a leak on your main water supply.
