I can go with re-positioned tubing or remotely actuated valves. In principle the tubing is easier, but I'm trying to think through all possibilities before deciding, and just thought of a new option. There's six tanks per side, and the tanks are small so it would be a challenge to put a mushroom valve inside each tank. Besides, that would be a dozen valves. However, I could also do just two valves per side, mounted outside and above the tanks, with very short hoses or tubes leading from three tanks to each valve. There is space, and because the valves would be outside the tanks I have a lot more freedom for the size or geometry of the valves. Maybe even normal ball valves actuated by a little air cylinder. This system would allow for fore-aft and side-to-side control, and would be highly resistant to list-induced water blocking. </div><div id="yui_3_16_0_ym19_1_1492269432664_51907"><br></div><div id="yui_3_16_0_ym19_1_1492269432664_51909">Anyone have thoughts on the KISSest way to control valves?
