I have 2 problems,1 our house toilet has an air sound when flushed and now it's bubbling when we use the sink or shower and the water level drops in the toilet. 2 our garage toilet has a leak from the base. We just replaced the wax ring this weekend and it flushed fine. Had to remove toilet due to a clog. Trying to figure out myself without having to call a plumbing in due to the cost of one.
