Booster Pump for Irrigation
Pressure from my well/pressure tank is insufficient for irrigation. My setup now, which is hopefully somewhat short-term, is that I ran some PVC, about 200' feet worth, from the garden area to the spigot/hydrant. I then just use a 3' hose to run water to the PVC. This was to avoid running 200' worth of hose across my yard.
The pressure at the other end of the PVC is not sufficient to run sprinklers. What I was thinking was installing some type of booster pump. Perhaps run a hose from the hydrant to the pump, then from the pump to the PVC down to the garden. Can anyone tell me if this can work, and any considerations I may need to take into account?

Does the existing pump still cycle on and off, proving that the irrigation system is not overdrawing the well?
If the pump runs continuously with pressure dropping to near zero, then you may need to operate fewer sprinklers at a time (and have more zones to handle all of the sprinklers).
If you do have enough water but just not enough pressure, nstall another pressure tank, preset to a higher pressure as is the new booster pump pressure switch, after your booster pump.

200' of 3/4" PVC. The pump still cycles on and off. All I was trying to run was one sprinkler head, the type where the water pressure causes it to oscillate. Only there is not enough pressure to do that, so it gets stuck in one spot a lot. So I suppose a tank with a higher set point is my best option?

I believe the cut in/out are 30/40. I could raise this a bit, but looking at some of the plumbing, I am not sure I want to raise the pressure in the house without first making some repairs.

It sounds like a booster pump might help. You could boost the pressure to just the irrigation line without worrying about blowing something in the house.
Do you have power available near the hydrant? Then the next question is how automated do you want it to be? Something you turn on/off manually when you are irrigating?

Yes something manual would be fine, since it would probably be easier to set up, and this hole setup is hopefully going to be removed for something more permanent in the future. And yes there is an outlet nearby to the hydrant.
