I currently have a 3/4 HP Red Jacket shallow pump (I guess it is a push/pulltype) which generates around 45psi which I replaced about 8 years ago and added 220VAC to the pump. It puts out around 5 gallons per minute out of the water spicket. I am installing a irrigation system (sprinkler system) and I don't believe the current setup I have will support my house and the yard with water adequitely. I am considering removing my push / pull 3/4 hp Red Jacket setup, including the black pipes down to my point and installing a submersible pump around 3/4 HP to adequitely supplying my yard and house with adequite water supply. I was also considering installing a 1 HP submersible pump and adding a second air bladder (tank) for the supply. One of my problems will be where the top of the well is the prior owners installed an house addition. Now to access the top of the well I will have to dig 2 to 5 feet in my crawl space to access this point. For the professionals out there who do this stuff often, what am I getting myself into and is this a good route to take for me at this point? Any advice or ideas would be greatly appreciated. Thanks in advance.
