Hello all thank you for welcoming me to this wonderful forum.
I am designing a system for on-demand water and low pressure, low volume irrigation throughout a 1 acre property. My desired flow and pressure is about 15-20 gpm@ 30 or 35 psi thereabouts.
The well is a 45’ length of 2” pvc in a 60’ hole. The stagnant water level in the well is about 3 to 5’ below ground level. I’ve yet to determine the flow rate but I’m fairly sure it’s tapped into the aquifer.
I have been looking into shallow well jet pumps (Recommendations?)
A minor obstacle I’ve run into is the fact that I intend to use a pressure tank, pressure switch, and a cycle stop valve to provide constant flow and pressure, using independent timers to control irrigation of each zone rather than running the pump from a timer, so that I’ll always be able to hook up a hose and have water where I need to use it.
The problem is, virtually all of the shallow well jet pumps I’m seeing on the market have the pressure switch included, and as of some literature I have seen, the correct position for a pressure switch, especially for a system where there is something generating back pressure like a CSV in line, is directly adjacent to the pressure tank with the CSV coming before everything. I could see how this could potentially cause the pressure switch to do some wonky things.
Would it problematic to remove the pressure switch from the pump, cap the tubing, and move it to the tank tee assembly? I’m assuming I would have to splice more wire to the pumps connections as well so that they could reach the pressure switch. Also would this void a manufacturers warranty?
As an alternative, can anyone recommend a shallow well jet pump, or any reasonably priced pump that will get the job done and does not have a pressure switch included?
In terms of a power supply, im assuming a 120AMP box is enough? Do I need any type of power supply control unit or anything of that type? I’ve seen people using power supply boxes with capacitors and whatnot. I’m not exactly the electrical expert.
Soon I’m going to pour a concrete slab to mount everything to and build the pumphouse around. Should I pour concrete right up against and around the well casing? Just wondering about potential vibration. I would be thankful for any experience or knowledge you could share.
So in total we’re looking at:
Foot valve
Pump- 3/4hp?
Cycle stop valve
Tank and T assembly-
Pressure gauge
Pressure switch
Pressure tank (35g?)
Flow meter?
Hose bib
Some type of master shutoff valve on either side? Is this necessary?
After that I would have some type of filter as I intend to use drip emitters and mixrosprayers with potentially easily clogable heads.
I plan on running 2” pvc in a perimeter around the property in a grid with strategically located spigots with 2 or more hose bibs (per spigot). This is where I will be able to put the timers, or hook up a garden hose. Then I will run poly tube from the timers and punch the poly tube for the drip emitter and micro sprayer inserts. I like the idea of using 1/4” polytubing from the main polytubing to drip emitter heads or micro sprayers on small stakes.
If there is any plumbing hardware you recommend, or microsprayers or drip emitters you like, or if you have any suggestions on how to improve upon my design, I’m all ears. Thank you for your time and your input.
