hello I am trying to pick a well system. I know little about wells. I purchased this land and the well was already here. had well company inspect, flow test and water sample. well depth is 340, static level 241' when they flow tested they pumped for 15 minutes and got 22gpm static level drew down to 248.4' they pumped for 45 minutes and the water sustaind and took about 6 min to start recovering. I have had three different bids on a pump installation and no one seems to be able to give me solid information on what type of system I should put in. I am planning on building a house with 2 baths, shop with bath, water some lawn and have a garden so I think I want about 15-16gpm that's one question I seem to get unclear information on. I have been mainly looking at the goulds pumps 2hp10gpm, or the
3hp13gpm the 2hp only gives me about 13-14gpm and 3hp is about 16-17gpm and both are off of chart looking at 260' pumping level that's static level plus distance from well to pump house that's another question I seem to get mixed answers on. so then someone said something about constant pressure system when I asked what that system is he said look it up online so I did and found lots of bad info until I read on here about csv valve what does that do exactly. so how many gpm do I really need what footage do I use when looking at flow chart my pump house is 14' from well do I count the distance from pump house were the pressure tank is to the house because that's another 100'. I have read about total head and then I get all sorts of confused. I had another well outfit tell me I need to look at the flow chart in the 330' colum since that's were the pump will be then I was confused again. I only want to do this once and 6-8k seems like a lot of money when I am doing all the reserch. also two outfits told me if I go with the 3 hp motor I need to use 1 1/2" pipe that added 1300$ to the bill then another one told me I only needed 1 1/4" .I don't know if 1300$ is worth 3-4 gallons a min. when I read about constant pressure system some said pumps didn't last that long others said power bill was to high.so any help would be helpful.thanks
