I have a similar arrangement on my M=17 without the check valves. With weight in the stern, water backs into the cockpit, which I solve by installing corks in the drain holes when more than one person in the cockpit. Need to remember to remove them when leaving the boat however. The cockpit seems to drain while moored in the water at the dock.
