GamaTech 110V 145PSI Digital Adjustable Pressure Switch Controller for Water Pump and Air Pump, 1/2" Male NPT

I had issue with water pumps pressure gauge keeps going ( comes with pump). Wasting my Battery Bank , I replace it with GamaTech 110V 145PSI Digital Adjustable Pressure and it works great I added two check valve one before the pump and one between the pump and the pressure gauge and works the way i want it .

Found how to toggle the water sensor and subsequently E-F error: Press and hold buttons #2 & 4 at the same time for 3 seconds. It will turn disable the pump (if running), display F00 and enable it again. Being a toggle you can simply repeat the above and re-activate the feature. Ref: https://m.media-amazon.com/images/I/81IuBW9F1HL._US800_.jpg My review was going to be just this: The first thing is a missing manual, second throwing an invalid error E-F to protect my pump which is not needed. Otherwise it would have been a great product. I need to operate in less than the normal 20lbs pressure range and this solved it if it just wasn't for the "protection" feature which causes great problems. I came here hoping I could discover how to turn off this feature. Unless I can find a solution this goes into the trash.

After trying different mechanical pressure switches over the years for my air compressor, this digital pressure switch is night and day better. Allows me to individually set the lower pressure (on) and upper pressure (off). Seems to be fairly accurate and consistent. If I had to complain about anything... I ordered this expecting a device which was black in color as shown in the description image. What I received was a light green/turquoise pressure switch. It takes some getting used to visually, but works great. Hope this helps others.

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.

For 11 months it worked, but when calling for high water flow, the built in protection turns pump off. I have a protection system on my pump already and do not need my pressure switch to "protect" my pump. I need it to turn on and off at preset pressures. Now it doesn't turn pump off anymore although it indicates that it is. Must replace in less than a year. UPDATE: Replaced again because of something unrelated. The new switch sat on shelf in box for a year. Installed and 1 week later it reads 113 or 114lbs at any pressure. Even a vacuum. Replaced with the one I removed until I find something better. Can't return because it sat for a year. Waste of money

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.

After trying to find a digital pressure switch for my well pump and not wanting to spend $500+ for a name brand pressure switch (that didn't have great reviews), I decided to give this a chance. I just got it installed and everything seems to work well so far. The wire colors appear to be UK standard, so ground is the Yellow with green stripe, Blue is Neutral and Brown is Line. converting that to standard US, Yellow-Green goes to Green, Brown goes to black, and Blue goes to white. Keep in mind, this was what worked for me, do you own research and take precautions. Setting up was extremely straight forward which I was very happy about because there is no documentation other than how to change the pressure setpoints. For the price, there doesn't appear to be any competition and having the ability to set the high/low pressures so easily and precisely I would definitely recommend this. Longevity of this part is still in the back of my mind though. Update, almost 2 years and still working great!

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.
