I just wanted to thank som eof you who helped me with ideas for setting up my new ballast pump system. Ty for the referral to BE Atlas for the pumps, Bob for the relay idea, Dane for the wiring diagram for the relays, James for the info on different pumps GPH rates. I finished putting in my two Simer pumps last night and tried them out withthe garden hose today. Too cold to go to the lake and my wife si really sick, so actual times will have to wait till later. I am estimating about 7 minutes to fill and drain. I ended up running a straightline from the thru hull (2) to the pumps, then to the sacks. No valves to turn anymore. Just hit the switches, and fill, then hit the switches and drain. <BR> <BR>Again thanks to all who helped, and especially those named above. <BR><img src="http://www.wakeworld.com/MB/Discus/clipart/smile.gif" border=0>
