Hi *,
I am thinking about a solution to protect my water pump from frost. This winter, I was too late to drain it and it was torn in half. It is not connected to a tap, but to rain water tanks.
A perfect use case for an automation.
But how?
The pump has two 3/8 " sockets, one to drain it and one to refill it.
My Idea is to use 24VAC valves with 3/8" threads. But I didn’t find any.
First question, can someone recommend such valves?
Draining would be easy: just open the valve when the temperature drop below zero degrees.
But how would I automatically refill it?
I would need some small water reservoir, which itself is protected against frost.
How would I do that?
Looking forward for any suggestions!
Thanks,
Ck
