Dear Irene,
I am no professional. but offer the following for your consideration...
Test your floor in the area that will likely be the spot where you intend to locate the piano. I have confidence that if the home is new that it will easily bear the weight, but you can test anyway. Simply have someone, preferably a heavyweight, 200 pounds or more, stand on the spots where you think the corners of the piano will sit. Perhaps a slight jumping motion would help. If the floor doesn't "give" when you do this, it should hold up the piano nicely, even though an upright piano might weigh as much as 600 pounds. Think of it this way, if the floor holds four big people where you plan to locate the piano, the piano will be OK there. I would suggest that you place something under each corner to spread the weight, so that more of the floor is bearing the piano's weight at each corner. A piece of plywood 1/2 inch or thicker, about 6 inches s.quare would do nicely, or you can buy something similar at any Home Depot or similar store, about the size of a saucer. The piano is about equal to the weight of two large people on a large bed, so what works for a large bed should work equally well for your piano. Because the piano is so heavy, you should put the spacers under each corner anyway, to protect the floor from being damaged.
PLEASE NOTE: PROBABLY WOULD BE BEST TO KEEP SOMETHING BETWEEN THE PIANO WHEELS AND THE FLOOR WHILE MOVING IT, AS IT COULD LEAVE "TRACKS" EVEN ON WOODEN FLOORS, IF YOU SIMPLY ROLL IT FROM THE DOOR TO ITS CHOSEN PLACE. tHE WHEELS ARE USUALLY SMALL. AND WILL EVEN LEAVE TRACKS IN HARDWOOD IF YOU DON'T PROTECT IT DURIND THE MOVING PROCESS. ENJOY..
When you have installed your piano, please play Peg o' my Heart for me. Whenever I move my piano, that's my ritual. I hope you enjoy your piano as much as I always have mine.
