I'm piecing together my plumbing before I'm forced to sweat it together myself due to lack of funds. Praying for a miracle before it comes to that...........but anyway (who cares right?). Every utility sink I've seen does not have a "air gap"/"water hammer arrester", but why not? It was my plan to do so, since I have the option, but should I just give up on the idea because there is a particular part I can't find. This is going to be hard to describe, but I'll try. I was looking for a brass (I think they are called) drop ear tee. 1/2"c x 1/2"c straight through w/1/2" threads at the tee for my stub outs. Does that make sense? So, the fitting would be vertical with 1/2"c feed in the bottom, then straight through with 1/2"c out the top for the air gap and 1/2" threaded nipple in the middle (at the tee) stubbed out of the wall for the faucet. Whew......got it? I can't find a brass fitting like I described, only 90 degrees. Here's my other question (same deal), should I air gap my water tap for my refrigerator's ice maker? Should I give up and just skip the air gap for these two outlets? Opinions........

I have strong evidence that the water pressure in our new house is very high- high water velocity at the facets, noticeable flow noise when using fixtures, not only the washer but even the toiler sometimes makes baning noise when it stops filling up the tank. I know I can install the pressure reducing valve to address this issue but I was thinking of two other possibly more attractive alternatives. 1) wouldn't simply closing the main shut off valve some amount reduce the pressure? 2) I was thinking of installing whole house filtering system for other reasons. Wouldn't it also reduce the pressure? Thanks for your comments in advance.
