Ok so I just needed to look a little longer. Found this on ebay I think this could work, I am just worried aout the amount of pressure it takes to open the valve. It doesn't say on this valve all the others quote a 1 psi crack pressure. Does anyone know if that would be too much for the pump to handle?http://www.ebay.com/itm/Stainless-St...-/120762701440 I think I would installing after the ball valve befor the kettle.
You will want to install the check valve below the element. Where it sits now, it will function to keep wort from entering from the tun. You will want it below the element so that when you turn the pump off during recirculation, it will trap any fluid above it inside the rims tube. 1psi is nothing to overcome via the pump. It should work fine.
