Thread: Delta Diamond Seal Technology

  1. #1

    Default Delta Diamond Seal Technology

    I am researching a new kitchen faucet and came across the Delta Signature Pull-Out (472-DST) which uses their Diamond Seal Technology. Price difference between the faucets with/without this new technology is very small...am wondering what the pros think....opinions, please. Thanks.

    It's what Delta is calling their ceramic cartridge line. Too new to have an opinion on it. Delta stuff is usually pretty good for longevity so I would be surprised if there were any problems with it.
