The best solution for your well pump!
Works with both 110V and 220V. Specifically designed for North American market with true 1/2 inch male NPT threaded connector and PSI units. It is the perfect replacement for the unreliable mechanical switches with springs.
Well water shortage protection feature
With a regular pressure controller, if your well runs out of water or the inlet pipe is broken, the pump will run continuously trying to build up pressure until it will eventually fail. GamaTech pressure controller is designed to prevent such a scenario by automatically detecting the water shortage and shutting down the pump. The display will show “E-F” and the red “Protection” light will light up. After the water shortage problem has been solved, press any button to return to normal operation mode. If not needed, the water shortage protection feature can be completely disabled (see manual).
Water leak protection feature
If there is a leak in the plumbing or a faucet is left open, with a regular pressure controller your pump will run continuously trying to build up the set high pressure. GamaTech controller has a protection feature that prevents any water damage to your house by stopping the pump. Feature is disabled by default (see manual to enable).

Bought this after trying several other pressure switch setups for my irrigation pump. I feed off of a lake with a high volume pump (max psi 43) with pressure tank. Mechanical switches cycled too much and was going to shorten the life of pump. Tried an inline switch that water ran through but could not adjust pressure settings. Bought this easy to install, setup and worked great for a year. Wouldn't shut off last week something failed internally. Contacted Gammatech after trying several tests and they sent me a new one several days later under warranty. Great customer service and still love product.

I have been running this for about 2 months, and it works so much nicer and is so much easer to set up that the manual spring type

I ordered this $59 replacement to the generic mechanical pressure switches available at Menard’s, Home Depot, Lowes, etc. made by Square D & Merrill that sell for $18 - $25.I installed this device less than a week ago, and it has been easy to set and let run with my 2-wire 230v 0.5HP submersible pump set at 85 ft. I liked the stated separate, easily adjustable cut-in and cut-out pressure set points, and corresponds well to my fluid-dampened bourdon tube pressure gauge.It starts and turns off my pump like clockwork on each setting. I’ve noticed some reviews stating they saw a delay in shut-off, which can be programmed as well, but I chose to leave that at default.I woke up at 4:30 am 2 days after installation with no water when flushing the toilet. I checked the pump room and found an error code displayed on the controller, no pressure on the analog backup gauge, and immediately wondered WTF. To cancel the error code, you simply push any of the 4 adjust buttons and in my case, my pump started running like normal up to my programmed 65 psi cutoff (40-65 psi set).What happened next was interesting. As soon as the pump kicked out, my 80 gallon pressure tank blew down from 65 to 40 psi in about 10 seconds, indicating massive abnormal flow somewhere. I watched the pump and tank cycle the same way again and shut off by the switch safety algorithm while I had eyes on it.I checked all the house and outdoor spigots, no leaks or bursts, nothing running. My supply piping has 2 check valves, one at the discharge outlet on the pump, and one in our pump room just upstream of the geothermal tee. Our geothermal pump & dump system was running at the time, and has a fixed 5 gallon/min flow restrictor in the system. I turned the thermostat to OFF and the abnormal blowdown immediately stopped.Bottom line - this safety feature in this switch saved our ass within two days of being installed. No doubt our submersible pump would have pumped dry and burnt up if we had our old mechanical switch on it.It turns out normal geothermal operation the storage tank allows operations in the tens of minutes before the pump cycles on. A new 5 gal/min fixed orifice flow restrictor is on order for and yes it’s balls hot outside 29 July - 1 Aug 2024.Notes: For 220V wiring, you have 2 bundles one for power (inlet) and another identical marked outlet (for your pump). The yellow/green wire is for your ground. The other 2 wires, white and black, are for your hot wires (included brief user manual included actually states this). So a normal 3 wire 220V cable has red & black hot wires and a white for neutral/ground.If you get confused, read the documentation. The control wires white & black are switched on and off while the green/yellow is not.Well worth the money!

Works great to cut on when the pressure drops, but it tends to have a delay when shutting off once the pressure has reached the maximum

Installation was straight forward. I used a contactor because it’s controlling a 3hp submersible pump. Set the low side to 80psi and the high to 135. Pump turns on exactly at 80psi but the high cutoff overshoots a little (5-15psi)Read the instructions. There is a cutoff delay built in but you can set it as needed.

High accuracy digital pressure display with on and off start and stop. I read the reviews and was surprised to see that some of them are misleading and have nothing with the switch, like shipping packaging.. It is very accurate and heavy duty, instructions are clear and it works great on my water pump. Great product and the fact that it has NPT thread makes it easy to install.

It comes with what appear to be 16 AWG stranded wires on both the input and output sides. I’m sure that’s enough for the average 1/2 or 3/4 HP pump, but I don’t feel confident with the pumps power running through this, or connecting solid wire to stranded 6 times, although I’m sure you could hide them in a junction box somehow if you ran a 6”nipple through one under the switch.I think the best way to use this is to run the main pump power wires through a 240V 40A contactor, and then use the stranded wires on this gauge to switch the contactor. The instructions recommend this for pumps over 1.5 HP, but I think even for smaller pumps you’ll get a cleaner installation, that’s more reliable, and has better connections.

I looked around for a pressure switch for my well pump and this is the best bang for your buck. Easy to hook up. 120 or 240v. just set the desired pressure high and low and watch it do its thang. :)

Really cool switch.However, it comes about 5 psi off right out of the box. The instructions for calibration instruct you to calibrate it when there is no pressure. Which is only possible if you install another switch out to the well pump, or else the pump will kick on, which means you have pressure. (Since the pressure switch itself needs power to calibrate it)

Why did I wait that long before buying this. Using for 2 month and works perfect.
