I’m sure someone has thought of this. I would like to put a electronic sprinkler valve on one of the bibs (outside faucets). I have easy access to these water lines in the basement. The bib is above grade and will never be hooked up to something that runs underground. The main purpose is to create a zone that can be used as a controlled sprinkler (in this case for plants that are hanging in front of our garage). Here are my fundamental questions.
What type of electronic valve do I need? I know that it is 24VAC. However, many of them are plastic inline valves. Whereas, the water line to the bib is all copper piping. I have no problem working with copper piping. Is a brass valve required for this application? I’m trying to avoid that because most of the brass valves are very expensive. Can I use a simple sprinkler electronic valve?
I currently have a 16 zone system with 13 zones utilized and a Master valve. I can easily connect the above valve for the bib as zone 14-16. But here are the questions. Do I need to reconnect the bib copper piping after the Master valve? I know it is safer. That said, I can see all of the bibs and will know if they are leaking. If I don’t tap into the water line after the Master valve and use zone 14-16 – is there any harm in this. More specifically, the bib would be connected as is to the water supply of the house, but when engaged both the zone and the master valve would be opened. I’m guessing there is no harm in this because the master valve would be open without an irrigation zone be opened (zones 1-13). Is that ok?
