Hi, IВґm a new happy Regal owner, 292 -98 boating in Sweden. I didnt get a owners manual with my boat, and I have one problem, emptying the waste tank. On my AC/DC panel I have a switch marked Waste pump, when I turn it on I hear the macerator working and my through hull valve is open still nothing happens?! any help you can provide IВґll really be thankful ! Thanks
