GamaTech Pressure Switch for Water Pump and Air Pump, Digital Adjustable Pressure Controller, 110V, 0-145 Psi, 1/2" Male Npt

Best well pump digital controller on the market today. I tried multiple ones with springs and were very bad and hard to impossible to adjust. This one is very easy. I have 2 pumps one 110v and another 220v and both versions of this switch work great. Rau to set the high and low pressure and has built in pump prime detection at low pressure. It saves me energy and the pumps by minimizing the starts and stops. I fully recommend it,as it is NPT connection, and psi redings easy to understand. No need for small leaking flimsy pressure hoses. Easy to install on the pump line that goes to the house with a T. Lasts long time.Update after almos o.eyear of using: still holds pressure accurately, no maintenance to do to the sensor, great product, I will purchase another one just as spare. Very reliable simple to use product. Highly recommend.

It works great, I am using it as a pressure regulator valve controller in conjunction with a solenoid operated on/off valve.Works much better than the mechanical regulator valves which allowed pressure to rise slowly above the set pressure. With this setup, when the set pressure is reached, all flow from the source stops and no more pressure creep.

I like this controller very much. You just need to know that they ship it with a 3 second delay on the high shut off which caused me a problem because our pressure builds up very fast on our system. I had to adjust it to 0 Delay and it works great.I had the high set to 45psi and it got to 60psi before shutting off so this can be critical to know. And they did not send the full instructions so I had to look at the listing on Amazon to find the instructions. If you have a system that builds pressure very slowly it may only build 1 or 2 psi above your set point.

I have been using these for years. Much easier to adjust than the old fashioned mechanical pressure switches. Just set the upper and lower pressure limits and you are done.

Worked well for 2 months but now it activates at 95psi instead of the 85psi that it is set at.

I used this digital switch plumbed to a sprinkler pump from my newly installed cistern tank. I have had it all summer and it has worked flawlessly. Easy to adjust compared to the old school contact point type pressure switch. Worth the money and worked good for me.

While I will say it was easy to install, seems to be very accurate, and did seem to fix one of my issues with my system I can not recommend this simply because the wire guage is too small. At my best guess the wire guage for the in and out is only 16 AWG when to my understanding it should be closer to 12. I also wish the in and out lines were much longer. After I hooked it up to my 1hp Shallow well pump it did turn on and run for a while. The wire got very warm not enough to cause them to melt in anyway but warmed than I felt comfortable for them to be.

Great product.My first unit apparently had a water leak and stopped working, I returned the unit and received another. Again it appears to be working just fine.I would note that the green "run" light does not mean that the "well pump" is running, it means that the unit is powered, strange way of doing it to me but just so you know. With my last switch I was unable to tell whether the pump was turning on and off for sure. While waiting for this switch I wired a switch to the wall in our kitchen which allowed us to turn on the well pump there and I wired in a light so that we could see if the well was on or not. I left this setup in place so now every time the well kicks on so does the light so there is no question of the pump turning on and off now.I also returned my old dial pressure gauge to the system so that I could see the water pressure, I am noticing that according to the gauge this unit is not overly accurate on it's pressure reading, but not really an issue as I can use the dial gauge and adjust the electronic switch as needed that way. I would note that I am running 23 psi max pressure which is unusually low, the idea that the switch may be slightly less than accurate at and below those pressures is not really surprising.Again I am happy with the unit and would suggest it to anyone who wants to get away from the old points type switches which will only operate within the designed pressure ranges.I also have a 20 amp relay that I have wired up to the output of this switch unit to be sure that it is never overloaded or anything. I can buy relays for $15 which is a lot cheaper than replacing this switch. This switch is rated for 10 amps and my pump only draws about 5, but if I ever put either of my big well pumps back in the relay will run them just fine where this switch would not be enough to do so.
