SharkBite 3/4 Inch Ball Valve with Drain Vent and Mounting Bracket, Push to Connect Brass Plumbing Fitting, PEX Pipe, Copper, CPVC, PE-RT, HDPE, 24616-0000LFA

PERFECT FOR INSTALLING WATER FILTERS AND/OR SCALE INHIBITION SYSTEMS FOR TANKLESS WATER HEATERS SO YOU CAN RELIEVE PRESSURE WITH THE DRAIN FITTING, AFTER TURNING WATER OFF IN ORDER TO CHANGE CARTRIDGES/FILTERS

Installed two of these in minutes. Just turn off water, drain line, cut out the correct length of pipe,clean pipe, insert pipe all the way on both ends. Turn water on, open valve to get air out.

I had a bad ball valve in the crawlspace, this beats sweating the pipe in such a tight spot, plus as an added benefit I did not need to complete drain and dry the system, It has a drain and the drop ear which allowed me to hang it up.

A little difficult the firs time using PEX. After a few tricks learnt from YouTube it became less difficult

Quick shipping, quality product, great price.

I love these push to connect products. Made installation very easy. Product works as described.
