Smart Pump Controller with 2 Metal Pump Connector, BSPP G1 Threaded Interface, 2 Modes Digital Display, IP65 Waterproof, Adjustable Pressure, High Power, for Home, Garden, Industrial Use

This has proved to be a valuable addition to my well water system easy instal easy programming and has been working for a year, no problems!

Very good product and works very well. Only took off one star because British Standard Pipe Thread (BSPT) doesn’t play well with NPT in the US and it can be a pain to get adapters. Amazon has them but it is an extra expense. Surprised that they haven’t made NPT only versions. Now with Tariffs I’m guessing that really wont happen. Oh well.

Very easy to retrofit an existing pump with this pressure switch.

The controller worked exceptionally, as expected controlling the water pump, only concern is what is powered up it lost the last setting

These are 1” threads in and out of this pump. I had to reduce down to the size I needed which was inconvenient

Yet to install - had to order more parts because the "kit" in not complete. This device takes European G (BSPP) threads on both input and output. The version I bought is advertised as a kit with adapters for US NPT. However, it only has one adapter - two are required to install in a US plumbing system. Furthermore, European G fittings like this require a gasket since they are not tapered and no gasket was provided - so it will most likely leak. I think they 'intend' that you screw the one provided adapter down hard on the plastic pump fitting - but that is neither reliable nor wise as you may break the plastic fitting on the controller. So, I have to buy 2 G1 (BSPP) females for US 1 NPT with gaskets.

It work fine. It turns the pump on at the lower limit and off at the upper limit as well. My only issue is that there isn't an on off switch/button and it resets to "bar" instead of "psi" every time you remove power. It DOES remember my settings though.
