Answer: 
Hi Kevin-
Sorry your previous question was not answered. you can reduce the pressure by loosening the lock nut and turning the adjustment counter clockwise. This should reduce the pressure to your desired level.

Rated 4.1 out of 5 by 11 reviewers.
Rated 1.0 out of 5.0 by Does not work--Most expensive i bought this to replace similar valve which i purchased less than 1 year ago from same place which failed..this one doesnot keep pressure as described.. plus installation is not easy.. June 7, 2016
Rated 1.0 out of 5.0 by Did not work The watts regulator did not function the way it was suppose to. May 10, 2016
Rated 5.0 out of 5.0 by Furnace Fix The regulator went on easily and solved my furnace problem. Glad Home Depot carries these supplies. March 29, 2016
Rated 5.0 out of 5.0 by Good product and easy to get from Home Depot. This pressure reducing valve is easy to install and adjust if necessary; just follow installation instructions. Nice to be able to get these parts from Home Depot rather than paying premium markup at local plumbing contractor. February 23, 2016
Rated 5.0 out of 5.0 by well made was better quality then what it was replacing,works great January 22, 2016
Rated 5.0 out of 5.0 by Exactly What I Needed To Feed My Furnace Humidifiers The pressure feeding my Honeywell humidifiers on 2 furnaces was too high. They are fed by a 1/2" line reduced to 1/4" for the final run. If I throttled the flow by partially closing the ball type shutoff valve, an undesirable noise resulted. After installing this valve, the humidifiers work great and there is no noise coming from the water supply line. December 16, 2015
Rated 5.0 out of 5.0 by As described - works and good quality It does the job and installed easily. At least at the retail level, it's the only one I found. July 21, 2015
Rated 4.0 out of 5.0 by Exact Replacement The old regulator wasn't working right and I had no idea on how to clean it and put it back together. This fixed the issue. Installation was a bit difficult. April 25, 2015
