1 1/4" Gate Valves?

link to all three mods http://www.asmskimmer.com/modifications.htm

finally did the recir and feed mod w/MJ1200 to my G3 last week, can't say a whole major lot of difference from before. Might need to either change feed pump, go direct from one of my two overflows or maybe some fitting inside the skimmer to get the water moving differently.

As for the gate mod, does give little better control, just because turning a knob a lot easier than pulling on a wet slimmy pipe. But even before the gate mod, keeping the water level constant in the skimmer compartment, skimmer production pretty stable.

Which gate valve mod did you guys do for your G3's? I see there is the standard one and an alternate.

Hi WWWD

I bought my 1 1/4" gate valve for aprox $18 at OA. I added the gate valve option to my G5 and it not only gave you better control of the height adjustment it also reduced the noise of the water falling from the outlet.
You are welcome to have a look at mine.

I completely forgot that I also bought a gate valve at OA for a skimmer. My bad. That's an option too.

Of the gate valve mods I did the first one (the second one has the valve after the T? or am I looking at the wrong page).

Yep okay on a G3, but that's not to say I had problems controlling before the mod, just easier with the valve. Had the pieces since I ordered them along with the skimmer from asmskimmer.com thought I should use them.

Found the bubble level would stay constant in the throat and would only need to adjust every month or two and that was after I pulled the skimmer and pump out for cleaning as would take a bit to settle down. If just taking off the cup and and rinsing it wouldn't need to adjust after putting the cup back.

Move the valve maybe 1/8 of a turn changes level in the throat by 1/2".
