While I had the 2011 RZ2 in the shop for the stereo and ballast upgrades, I had a chance to take in the OEM hose routing and configuration. I think i have isolated a couple of areas that could be address in order to reduce the passive draining some have experienced.
1) I think most of the passive draining is coming from the drain thru-hull. This is expected because the custom sac is higher then the thru-hull once the sac is full. Once the sac is full, the water pressure in the tank and sac are enough to push the water past the pump and out through the t-hull. Kind of like water over a dam. The best way to prevent this, IMO, would be to pull the drain hoses off the t-hulls, extend them and rout them over to the opposite side. No need for drilling holes, just hose, some clamps and a couple of hose splicers.
2) involves the configuration of the surf sac's fill and drain connections. I think they could stand to be reversed from what they are now.
Looking at the picture, the port on the left is the rear of the sac and is the vent. The port on the right is the front of the sac and is the fill.
I would swap the hose, thus putting the fill at the rear and the vent at the front. This would require extending the hose to now reach the back of the sac and swapping the gray T 180*.
