VERY NOISY. WHEN RUNNING IT, THE WATER BACKS UP BECAUSE THE RUBBER GASKET IS TOO HARD TO ALLOW THE WATER TO OPEN IT LIKE ANOTHER BRAND. IT TAKES A LONGER TIME TO GRIND UP BONES AND CITRUS RINDS COMPARED TO ANOTHER BRAND I HAVE USED.. YOUR ENGINEERS NEED TO MAKE THIS MORE EFFICIENT AND QUIETER. I GOT THIS DISPOSAL IN A NEW HOUSE AND WILL PROBABLY REPLACE IT SOON.
