I've never heard of the brick thing, and have run yachts for a long time. Maybe it's a northern thing, I dunno.
You need to locate your holding tank in the boat, follow the vent line and see if there's a charcoal filter on it (roughly a 2" thick tube and 18" long) these are usually made by sealand and should be changed every 2 years, if not remove the vent line (usually 1/2" hose) from the tank and try blowing it out with compressed air. The vent should be close to the deck fitting where it exits the hull. Your Y-valve may be in the wrong position, I would try filling the deck fill with a garden hose for 30 seconds and see if water goes down it, it may be as simple as moving a y-valve. This would be near the tank on one of the large hoses coming off of the tank
