    Need help with lawn irragation, I am currently using 3/4 hp submercible well pump from water source straight through no pressure tank I just turn it on and leave it on. I can run 2 large diameter sprinklers now but with reduced pressure, I am getting 13 gal a minute now, running 500 ft of 1in pipe. My question is I have a 1hp jet pump rated at 22 gal per minute, can I hook up the jet pump in line with my current system and gain more pressure and use it as a booster pump if so what would be the best way and place to connect to line. Please let me know if this will work.

    No. Leave it alone. You will get the 13 gpm, and no more, so it's up to you to spread it over your acreage. That's why they invented sprinkler systems.

    Lots more questions on wells and pumps lately. Sorry no answer for you from me. Just noticing the increased well/pump questions.

    I think we'll see more wells as our potable water supply shrinks from drought and demand and the cost for both potable water and its by-product (sewage) increases.

    So there'll be more questions about 'em. Here, a well is the way to go, what with our sandy soils and high water/sewer rates. To me it's semantics - they oughta give you the water 'cause they're killing you on the sewer bill anyway.

    Good answer, Boots. You can't get 10 lbs. out of a 5 lb. bag.

    Drop a larger HP submersible if there's enough water table to support it.

    12 gpm without violating the 5' per second rule, loss is 3 1/2 psi per 100'.

    You got some very thin-walled poly down there, bub.
