Product review (1 stars): Junk Buyer Beware!!!!!
This is absolute garbage.  First, it isn't for pex as advertised!  I installed the outlet box go to plumb it with 1/2" pex and it doesn't fit the connection.  I then purchase 3/4" pex and 3/4" pex is too large.  I went to Lowes with the fittings and tried several pex fittings but none of them worked.  I ended up buying another outlet and separate water hammers at the tune of $91.  I will think twice from buying from Amazon in the future until they can make sure the junk that they sell is actually correctly advertised.  The plastic is also flimsy so flimsy that you can see through the "Y".  Again, absolute garbage!  Thanks a lot Amazon!
