Product review (1 stars): Terrible Quality Control
Purchased this valve in late January 2014 and received this in February and installed it a week later. Went in without a hitch and added a new filter and inlet as well. Worked great till this morning when my water alarm went off in the basement. The Solenoid valve was stuck in the open position allowing water to continually drain into my Aprilaire Humidifier and create a basement flood. Contacted the company about a replacement  and was told the Solenoid Valve has only a thirty day guarantee so I was out of luck. What valve is supposed to fail after three months of service????. Complete waste of money and time for this poor quality item and don't expect any help from the seller if you develop a problem.
