GamaTech 110V 145PSI Digital Adjustable Pressure Switch Controller for Water Pump and Air Pump, 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.

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.

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.

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!

Was excited to get this thing on my pump but it never shut off the pump literally went so high I couldn’t believe it when I read the gauge. Thankful the pressure relief was on there. So maybe others had good luck but for the money and poor quality or even a work work product I would look at something else personally

Met expectations shut off at user selected high PSI limit turns back on at user selected low PSI limit

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.

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 .
