Should any liquid but water enter a water strainer through a waterproof pipe, the result will corrupt a singleplayer world or crash a server. The corruption can only be fixed by using a map editor to remove the water strainer or by deleting the Power Converters mod. However if there is more pipe directly opposite the input pipe, the other liquids (oil,lava) will continue through the opposite sideFor what its worth I'd advise using a finite power source e.g. an engine requiring fuel or if using energy link use a battery (not a solar panel).
