Hey does anyone no where to get a 1 1/4" gate valve? I am trying to do a gate valve mod on a G3 and went to terrison and they told me they don't stock them, they said almost knowone does these days. Any help on where to find one locally would be great.

by gate valve do you mean the ones that are adjusted by a screw device or just a slide. Slides are common thru hot tub dealers sometimes called a knife valve, and threaded ones from andrew sherrit 1 1/2 '' is about it so you'll need reducer bushings, ps get glue in ones that are threaded so you can reuse valve .

I went through the same pain for my G3. I just ordered the kit from asmskimmer.com - let them source out the valves. Seems to me it wasn't this hard to find them a couple years ago .. I dunno maybe it's just an odd thing to want.

Thanks, someone pm'd me they have some extras.

They told me at the shop that noone uses pvc gate valves anymore, they have all switched over to ball valves. I have a knife valve I use on my return but because I need precise movements I need a gate, also the knife has a lot of metal in it, this will basically be sitting right over/in the water.

Tony do you have a pic of how you did you G3 mod? I remember seeing a page at asmskimmers.com but I can't find it now.

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.
