In reference to the leaks- my washdown hose was loose from the factory, an easy fix, but required some contortion. This year, the hose split just behind the hose clamp on the fitting that enters the pump. I also had this splitting problem on the freshwater washdown hose. I'm not sure of the cause, but it happened both times right at the fitting. Neither was a gusher, they both sprayed under pressure. So, check those fittings and hoses for splits.
