We just finished our first trip in our 2012 29' Sunseeker, the only casualty was the flush valve broke and flooded the bathroom with fresh water. Fortunately we caught it quickly and had towels nearby.
Two points I've come away with; 1. Always turn the water pump off when not using water and 2. These flush valves are made of plastic, I'd better order two. The link below is a replacement for the valve I need to order. Do you guys know of a higher quality part I can use as a replacement?
