The Delta Faucet Company, a division of Masco Corporation, manufactures Peerless brand faucets. In most cases, both Delta and Peerless, faucet repair parts are interchangeable. Until 2010, Delta and Peerless used the same ball, seat, and spring combination as their primary operating mechanism. In 2010, Delta distanced itself from Peerless by switching to a new cartridge technology. Peerless faucets remain as a quality utility faucet for the professional and homeowner alike. Repairing a Peerless faucet is fast, easy, and affordable. The average cost for a Peerless rebuild kit as of 2010 is around ten dollars. The normal repair time is about an hour for the novice, 15 minutes for a proficient do-it-yourselfer.
