I was wondering how practical it would be to use a Water shutoff valve if I have a well, would it be just as effective and most likely cheaper to shutoff power to my well pump?
I'm about to close on a new house and the plumbing needs some repair work, new well pump, water heater, and some type of water treatment installed. Seems like a good time to have a WSV installed if thats the route to go.
Our permanent home is in Indiana...On a well and I only get back there about 30 days a year. It is unoccupied, and after seeing a neighbors house w/water damage, I decided that it was in my best interest to turn off water when we left our home unoccupied.
However, in the winter...we turn our spa room into a greenhouse to overwinter many perishable plants....I've got grow lights (PLC control) and drip irrigation (on a timer) set up in the room to ensure that the plants survive. However, I am concerned that a frozen pipe will leave a continuously running well pump for a long time.
My initial solution is a 3-position master switch that sets power to the well to either home, off, or away.
1. Home- routes power to the pump normally
2. Off- cuts all power out to the pump
3. Away- routes power through a Normally open contactor. I then use an PLC relay to control the contactor
End result is that I can turn power on for a minute every other day to ensure that the pressurized tank has water to ensure plants get water. It also ensures that the pump will not run continuously with a broken pipe.
Next visit home, I plan to install a current sensor on the well pump to ensure that the pump is not running excessively, or when it isn't supposed to (indicating a pipe break).
