Hi we are planning on laying berber carpet in our sunroom. We have ask carpet experts in Home Depot and Lowes and they all say this is how we should do it. They say we can use double sided tape or glue it down to the exsisting plywood floor. The room is mostly glass and has a insulated ceiling. Its doesn't have A/C or heat. We live in GA. and we are wondering if this all sounds okay to the experts on here, or does anyone have any other ideals. We are leaning towards the double sided tape. Thanks for the help in advice.

Sump pump overflowed, soaked the carpet in my walk in closet, about a 5x5 area. Pulled up the carpet up to the door frame, removed the underlay. Underlay appeared to soak up most of the water so it's been air drying with a fan in the garage for 3 days(still damp). Questions: 1) Should I reuse this underlay or after 3 days of trying to dry it out, will it still mold? It's only a 5x5 piece so shouldn't cost too much to replace if necessary. 2) A bit of water seemed to have made it's way past the closet that I can't get to without completely removing everything from the room and tearing up the carpet. It's a very little amount and I want to know how long it will take to air dry with a fan blowing under before I can call it good and drop the carpet back down. 3) The water was sump water, no odor, just a slight yellow color. Is it dangerous at all(bacteria wise)?
