Solar Joules are catch and release
Also a water meter with contact closure (one pulse per gallon) running to a Raspberry Pi will tell you how much you are using per hour/day and have settable alarm limits.
BAM! It finally clicked for me. I already have a 30/50 switch like this in my system and all I need to do is replace it with one with the low pressure cutoff. My brain was trying to think of how I'd add the switch to the system. $30 and a proven decades old tech. Win-win. Thanks.Would a pressure switch with a low pressure cut off work?

If something is running continuously and your tank so in build pressure it will shut off power to the pump.
That's awesome. Simplest solution is usually best.BAM! It finally clicked for me.

What does a Low Cut-Off Pressure Switch do?Square-D Pressure Switch 40/60 with Low Pressure Shut-off
The industry standard for controlling electrically driven water pumps. Low Pressure Shut-Off operates at approximately 10 PSIG below cut-in and will turn off the pump.aquascience.net
A low cut off pressure switch turns the pump off in the event that the water pressure in your lines drops lower than the cut-in pressure (low number). Imagine that there was a leak or break in your water line. This would cause the pressure in your line to drop and your pump to kick on and stay on which could lead to flooding of your home or business. The low cut off pressure switch would turn the pump off if the pressure drops 10 psi below the cut-in pressure (low number). Think of it as a nice piece of protection.
Is there a tutorial for this?Also a water meter with contact closure (one pulse per gallon) running to a Raspberry Pi will tell you how much you are using per hour/day and have settable alarm limits.
That's what I need. If something breaks there needs to be manual intervention to start the pump and fix the problem.That's awesome. Simplest solution is usually best.
One thing to note- if the low pressure cut off is activated you have to go out to the pressure switch and manually flip the lever to switch it back on.
Thanks. I'm not concerned about the pump. My issue is that if the pump runs continuously it will drain the batteries creating a low voltage condition that will shut off power to the fridge, freezer, wifi network, etc. The loss of food is the biggest issue. Loss of communication is a moderate concern.We have two wells going into 2 cisterns, when there's cattle in the summer both wells run 20 plus hours on a hot day especially when the house is occupied and continuous if a float is broke, This has been going on for 20 plus years. It could be helpful how deep your wells are and how big a pump, That said I would not worry about it, if the well is deep your back pressure won't dry out the pump as another person stated your pressure tank also keeps things lubricated. Only variable is how much sand, dirt going through the pump wearing out your propellers. IMOP cheers.
Well, not exactly, but it's pretty straightforward, and there are lots of tutorials for setting up inputs. I use Python because that's the RPi ecosystem standard:Is there a tutorial for this?
Pardon but you also said you need for the pump not to be cycled too long from someone running water excessively. The pressure switches that require reset from having pressure drop to nothing (broken pipe) will not handle that.That's what I need. If something breaks there needs to be manual intervention to start the pump and fix the problem.
I don't understand what you're saying.Pardon but you also said you need for the pump not to be cycled too long from someone running water excessively. The pressure switches that require reset from having pressure drop to nothing (broken pipe) will not handle that.
There are a bunch of different failure modes that the OP is trying to solve.Pardon but you also said you need for the pump not to be cycled too long from someone running water excessively. The pressure switches that require reset from having pressure drop to nothing (broken pipe) will not handle that.
That seems to be a problem I have. Read WPNS post.I don't understand what you're saying.
That's correct. This is easily solves the problem of broken pipe, etc. which is my biggest concern. I'll continue looking at other monitoring solutions suggested for lesser leaks.Pardon but you also said you need for the pump not to be cycled too long from someone running water excessively.

One other thing you may want to think about is exactly where to place this "shutoff switch". In my situation, the pressure tank is about 40 feet from where the pipe from the well enters my basement. If I place a switch after or at the pressure tank, any break or leak in the 40ft of piping before the tank will go unnoticed. The well pump will just keep running in that situation.Hello,
I have a 120VAC well pump triggered to start and stop by a pressure switch at the Well-X-Trol storage tanks. I want to add an auto shutoff of some kind that will stop the well pump if there's a continuous draw such as someone leaving a frost-free hydrant on or a line breaking so the well pump doesn't run continuously.
I'm thinking that a timer that shuts off the pump after, say, 30 minutes of continuous use. To restart would require manual intervention after the leak is remedied.
I'm also open to other pump shutoff methods. I've searched several times for quite awhile and I must not be using the correct terms.
What is available to serve this function?
Thanks.
Well, you should never have the switch that far from the pump, but the low-pressure-dropout switch will take care of a broken pipe.One other thing you may want to think about is exactly where to place this "shutoff switch".

If I place a switch after or at the pressure tank, any break or leak in the 40ft of piping before the tank will go unnoticed. The well pump will just keep running in that situation.
edit: This is assuming you want to install some sort of valve/switch to just stop the water flowing.

Yes makes perfect sense.Thanks. I'm not concerned about the pump.

The generator is on AGS and will start automatically and that will eventually drain the 500 gallon propane tank, depending on how long I'm away. This $30 solution will prevent those problems.
Also, if the leak is in the house this will limit the water damage to 80 gallons or so.
