Since I like to tinker and "injuneer", and in the interest of keeping my darlin' wife a little happier, I've decided on this piece together system.

and this pump

I found some Hayward propaganda that claims the S180T "design flow" is 35 GPM. The
SP1592 is rated at 58 GPM @ 40' of head pressure. I decided to go with the two speed model so maybe I won't need to throttle on low. The two speed will use less electricity on low than a throttled single speed, and I think it'll make less noise. This system will cost about 20% more than the complete single speed system, but I think the complete system probably comes with the LX series pump, instead of the Matrix.

Is this valve

any higher quality than this one?
