>>2790243>There's a mesh filter in the housing of the solenoidThose are rudimentary and only for large particles.
I'm talking about mesh or screen filter that is placed over main line, something like this, drip lines usually require 120 mesh or greater otherwise they'll clog up with small particles over time.
You need to open it and clean every few months so best to place it close to shut off valve for easy maintenance.
>I need vacuum breakers on all my drip lines, and regulators?Not necessarily, you can step down pressure somewhere close to where line comes into your property, then it'll lower the pressure in the entire system this however will reduce your flow rate and hose pressure so it might be better to have it closer to drip lines, I have mine before main line enters my garden area to maximize length at higher pressure but after my main watering hose so it can operate on higher pressure.
If you want to keep main line at high pressure and only step down where it branches off you'll need a regulator in every branch off.
As long as your drip lines and other components are below their rated pressure it will work fine.
Keep in mind that height changes will affect pressure when installing your regulators, if you instal a regulator on low ground then pressure on high ground will fall a lot more and if you install it on high ground then pressure on lower ground will be higher, pressure changes by 1 psi for every 2.31’ of elevation change.
And I don't know exact principle they work on, I just know they step pressure down.
