Rated 3.0 out of 5.0 by Average Purchased this regulater a year ago for a new well. It failed in one year, have bought numerous regulators over the years for different wells but have never had one fail so quickly. Contact points moved somehow and it fails to make proper contact. July 28, 2015
Rated 5.0 out of 5.0 by Nice to work with. Easy to install The terminal connections were not clear, but figured it on youtube. If you need one, its not bad and will get the job done. June 26, 2012
Rated 5.0 out of 5.0 by Exact replacement Good product. I wish it was stocked in the stores. The one in the stores did not have as well known a name May 28, 2011
Rated 5.0 out of 5.0 by Replacement Control Hits the Spot! The old well pump pressure switch stopped working, so a new one was purchased from Home Depot to match the old one. The match was perfect, therefore the installation was easy. The old switch lasted several decades, and appeared to have failed due to unavoidable fouling of dirt and corrosion. I see no reason why the new switch shouldn't provide several MORE decades of reliable service! Terrific product!! April 15, 2014
Rated 5.0 out of 5.0 by was cheaper than any other store & it was the same product. product has worked excellent, for half the price of what I could find it locally. The customer service was excellent in helping me choose the right product. April 14, 2012
Rated 4.0 out of 5.0 by Perfect. Just what we needed. Great price. Easy purchase, having it delivered to the store. Great transaction. October 14, 2014
Rated 5.0 out of 5.0 by None Better I've used these in all the pressure tank applications I've installed throughout the years. While the design hasn't changed, it doesn't have to. They work and are easy to install and adjust. October 5, 2013
