Will I be able to get that alarm System sound when I lock my doors any way besides an alarm system.
How about a thick tire with a thickly twisted rope? Or a fire hose dog toy (made out of real fire hose material)? ^_^
This happened at my house-exactly as you're describing. It turned out to be sediment that built up in the drain gets disturbed when it's blasted with hot water. You need to access the drain and clean it, right there where the water gets blasted onto it and this will stop. Guaranteed! You may need to unscrew the small round plate with the holes in it, and clean the underside of that as well.
