That's right, I forgot it goes from a 1/2" to a 1/4" knuckle! Yes, one 1/2" generator works pretty good. I used it with the stock pump for a while and had good flow. I switched to a Hygger 260, mostly so I had a back up pump.I got two 1/4" that went directly onto the existing knuckles. The main knuckle is 1/2", so you can do what Scottj did. I think most go for the 1/2". If I purchased again, I would go with the 1/2". The 1/4" works but I think it would flow better with the larger.
So that means if i kept the existing knuckles and just replaced the nozzle, I would need the 1/4" for the dual nozzle and 1/2" for the single nozzle off of the main knuckle "Y"?That's right, I forgot it goes from a 1/2" to a 1/4" knuckle!

The knuckle on the wall is 1/2". The Y knuckle must be a 1/2" to (2) 1/4" reducer. So to replace the existing 2 nozzles, you would need (2) 1?4" RFG's.So that means if i kept the existing knuckles and just replaced the nozzle, I would need the 1/4" for the dual nozzle and 1/2" for the single nozzle off of the main knuckle "Y"?
