    Hi,
    We just drilled our well on our vacant lot for a future house here in Central Washington (the state). I think we got pretty lucky. The well is 6" in diameter, 77' deep, and we hit water at 65' in basalt. We got a water flow in excess of 50 gallons/minute. The final water level is 2' below ground level and we have 4' of well casing above the ground (the water level is about 6' below the top of the well casing). We plan to build a 2 or three bedroom home....pretty standard requirements and are limited by the County in irrigated land to 1/2 acre - a nice size garden and yard.

    I assume we would want to use a submersible well. I was just reading up CSV's (cycle stop valves) - had never heard of them before.. I have a Sta Rite 10gpm, 3/4hp 230v pump and control box, but would put it on **** and replace it with something else if recommended. I also have access to a Grundfos .33 hp 10gpm 230v pump (S series - not the constant pressure type).

    Any recommendations would be great...

    Thanks!!

    Also....one story house with floor level no more than about 3' above the soil level at the well...and about 20' to 30' away. Any of the irrigated property slopes gently downhill from the well at about 1-2 percent grade.

    The 1/3rd HP pump is probably marginal at best, and the ¾ HP maybe a little overkill. One of the benefits of the CSV is that it allows you to install as large a pump as you want, and still be able to use it like a smaller pump when needed. Another benefit of the CSV it that you only need a 4.5 gallon size tank. The smaller tank saves space, heat, and money.

    I would use the ¾ HP pump and control it with a Pside-Kick kit that includes the CSV1A valve, 4.5 gallon tank, pressure switch, gauge, relief valve, and wall mount brackets.
