PVB on an outdoor well pump overkill?

Will it be worth it to keep my PVB that I have connected after my well pump for backflow. I just want to be certain that it won't rob me of too much precious pressure needed to water my zones properly.

Also, how did you guys with well pumps test your installation manually for your zones? I'm making about 40-49 psi according to my gauge and flowing from valves to lateral pipes that are 1 1/4" (I should have good flow). I'm planning to try and get a wet test started tomorrow as well. Just want to make sure that I get everything right. Let me know on the PVB as well as testing my heads manually with the pump (i can manually turn on the pump relay). Thanks again.

Really no need to unless your well is also being used for potable water in your home

Should I go ahead and uninstall it then? It's actually already installed.

pressure loss is minimal. Leave it on!

Rule of thumb - open discharge gallons per minute divided by 2 = circuit design max gpm. In other words if you have 60 gallon per minute at open discharge you can safely design your circuits at 25 to 30 gallons per minute.
