Was just at hurina and he said it was a new thing, sorry. I've seen quick disc on etec before but they where the garden version. I'll check when home but i believe the owners manual asks when flushing not to hit it with 80psi coming from your source. Just requires the pressure that the impeller produces. The pic of the pisser hole has a pressure blow off so you cant over pressure your cooling. My stock pisser is just a black adjustable nut.
