Rated 3.9 out of 5 by 29 reviewers.
Rated 5.0 out of 5.0 by Accurate, easy to install and priced right! I purchased two of these gauges to replace one existing gauge and to add an additional feature to my home water system. I have gauges installed at the well head and the second 200 feet at the water point. These gauges then give an instantaneous alert of pressure drops caused by line problems or other pressure drops. The Gauges are easy to install, very accurate and value priced. Home Depot also carries every accessory material necessary to install and use these gauges. August 13, 2014
Rated 5.0 out of 5.0 by water pressure gauge small easy to read gauge at a budget cost, fits in small tight places such as ground meter box. perfect for my project! February 17, 2015
Rated 4.0 out of 5.0 by Easy to install and read after installation Easy to install, came with proper adapter so I could easily replace old gauge. August 26, 2014
Rated 1.0 out of 5.0 by Poor Quality It has a plastic case and lens which wont rust but feels cheap and durability is questionable. I installed this gauge and it was fine for a week. After a week it started dripping water from the fitting. I figured it may need to be re-taped with teflon but I was suspicious at why it would not have been leaking from the start if this was the case. The leak got progressively worse so I went ahead and re-installed it with new Teflon. Still leaking. At this point I went to remove it again and the brass fitting broke off inside the T pipe. It was never over-tightened. The entire time there was a hairline fracture in the brass adapter that come with this gauge! The brass is very thin. Luckily I was able to extract the broken piece and fish the old gauge from the trash so we could have water. That brass adapter is just adding another failure point. Get a real 1/4" gauge that doesn't need an adapter. March 10, 2015
Rated 5.0 out of 5.0 by Very nice gage I installed several of these gages on the low pressure side of my home shop compressed air system. They all read the same which I assume means they are fairly accurate. Great value. February 10, 2015
Rated 5.0 out of 5.0 by Excellent Gauge, Excellent Price Purchased this a the local store and it was about $1 cheaper than listed online. I'm very pleased with the quality of the overall build. The gauge is very easy to read. It comes with a smaller nipple (1/4" I believe) and a larger one that serves as an adapter (1/4" to 3/8" I believe). I installed it in minutes and I'm looking forward to many years of good use. October 26, 2014
Rated 4.0 out of 5.0 by Well Pressure The gauge comes with a 1/4" NPT adapter, so it installed directly on my daughter's water well header. October 1, 2014
Rated 5.0 out of 5.0 by Excellent Product Item came with TWO fittings to accommodate whatever size necessary for installation to the pressure switch. September 30, 2014
