I'm not very good with this stuff so I figured I'd ask before buying parts...
I bought this pump:
* Inlet: 3/8" FPT & 3/4" MPT Mounting bracket included Outlet: 1/2" MPT
* 115V comes prewired with 3ft cord NO PLUG
* 1/25 horsepower, continuous duty 1.4 Amp motor
* Max flow of 7.5 gpm
* center inlet (center inlet shown in picture)
You can attach a 1/2" ball valve directly to the 1/2" output, no coupling needed.
Be careful if you do this. Very easy to strip the threads on the pump. I put polypropylene 1/2" couplings on mine. (http://www.austinhomebrew.com/product_info.php?products_id=11184) Then added a nipple to the ball valve. If I strip the coupling threads, I just put a new one on. Pump threads will always be intact this way!
