Picture this, you have a 3-BR house and each bedroom are next to each other, separated by a door from each other. In other words, one can get from the first room to the third without going to the living room. Now, you want room 3 to smell good (expecting a company, perhaps) and thought about spraying febreeze. Would you spray in room 1 or 2 and expect room 3 to be as fragrant as the others?
i put my heaters in my overflow since i'm using a durso standpipe and it's empty space.
