So what exactly does the gate valve on a skimmer do? I just picked up an asm g3 and was planning on doing he recirc mod and i read about the gate valve mod. I have seen these on other skimmers and just assumed it was just part of the plumbing, What exactly does it do and is it worth doing?

It's a must, I would say even before the recirc. mod. The way you adjust the water level on a stock G3 is by raising and lowering the 1.25" pipe that has the foam filter on it. Trouble is for most of us it doesn't extend far enough to get nice wet foam. Also, the water falls back down the pipe, on a tight fit in the sump, it will likely be messy.

So to answer your question in a nutshell, Gate valve allows very fine adjustment to your water level in the skimmer. Also, better directs the water for less splashing and saltcreep.
