This is a follow up or a continuation of this thread
Here is what I have
And I nee d to insert an 1" female to female Orbit in line sprinkler valve between the green handle valve and the hose
It is 1" because this is what I got , the delta cost for going to 3/4" does not make the things simpler
everything that I have there is 1/2" and I am not sure what is the best way to do this or if it is OK to do this
The idea here is to make sure that the system needs two valves to fail in order to flood my house (or the hose and the main valve)
I want to make sure that while I am away if something breaks it has to be the control valve and either piping or another valve at the same time in order to have a serious flood problem
