the chiller came on about5 or 6 times yesterday. today its much cooler. the sump is protected from the weather by a patio. there is insulation on the bottom and three sides. having the sump on the outside makes it very easy with water changes, and you aren't really limited for room if you have other equipment, the noise of all of the equipment is outside, best thing I did was to move all of the equipment outside. the most noise I have inside is the overflow. I am relying on gravity to run water from the DT to the sump. The sump is about 25 feet away from the DT. I've tried different methods of muffling the sound but I found I needed the space in the overflow box as a cushion, otherwise for some reason, the water would fill the overflow and run onto the floor
