Seasick please go back and read wrxhoon's post. Read the entire post carefully. The livewell pump is not on and the livewell does not fill with water when the washdown pump is on. Two pumps. One hole in boat. Beautiful.
I'm glad someone understands how it is done guys, I would put up pictures for everyone to see but I can't as it is under the livewell and I don't want to remove it to take pictures.
ONE hole on the bottom of the boat thats all you need, ONE through hull fitting again thas all you need, srew the aerator pump on the through hull, this pump can be bought with another outlet ( dual outlet pump) the top outlet feeds in to your livewell and the bottom outlet ( this outlet is before the pump) feeds to your SECOND pump anywhere you like to install this second pump , this SECOND pump is a pressure pump with the outlet going to your washdown fitting , screw your washdown hose end to this. Do all the electrical connections and presto you have a washdown and a livewell both working with different pumps just like as if you had two holes on the bottom of your boat ( Grady do this 2 hole option). You switch the washdown pump on and ONLY the washdown will have pressure, you can leave this on all the time if you like as you press the trigger the pump will pump, trigger off pump stops unless you have a leak, you switch the livewell on only the livewell will have water coming in. I can't understand why GW don't use this option.
My set up saves another hole on the boat, another through hull, that would save them money in parts and labour!!
I hope all concerned understand how this set up works, I can't make any simpler.
