    Post What Went Wrong

    O.K., here is my problem. Perhaps it was posted before, but I am unable to find it.

    Recently my above the ground pump (Myers HJ50D 1/2 HP), located in the basement started making all kinds of noise, which I can here being upstairs bedroom. It still pumped the water but didn't shut off, unless mechanically forcing contacts on the pressure switch to disengage. Adjusting the pressure switch didn't do any better. To stop pump from running between 30-40PSI, I had to turn out the screw #1 when finally switch disengaged. In turn this was making spring on the screw #2 (cut off) loose, therefore validating desired preset. Furthermore after unscrewing #1 my point of "cutting in" was very low, which in turn forced mi to close faucet and wait for the pressure to build up.
    So I did adjustment the way to give me higher point of "cut in" and I worked as "cut off" switch by forcing contacts on pressure switch to disengage with wooden stick.
    Finally I've changed pressure switch for the brand ned SQ D 20-40. But that didn't help.

    Everything was OK until wife caught me frequenting basement. Her sweet question, "can you do something with this?" forced me in to action.
    I did check couple of contractor for the "in ground" deal, and it runs around 6K in my neighborhood. I am about 1/3 mile from the lake and figured out, that new pump in the basement should do.

    I did find same Myers pump, but with impulse of greed, I've ordered slightly "bigger HP" unit, the Myers HJ75D 3/4 HP. Pump is exactly same, just stronger.

    My setup is as follows:

    Outside of the house I have 4" capped pipe sticking out from the ground.
    Do not have any knowledge of how deep it is.
    When pump works sometimes I can hears hiss coming from under the cap.

    InsideMyers pump seating on the top of the Flotec tank.
    Since tank get seriously rusted from the water dripping occasionally from the pump, I've decided replace both items - pump and tank
    This time I've installed Flotec FP715-08 tank and Myers HJ75D with pressure switch 20-40, and i lowered pressure on empty tank to 18PSI
    I am guessing that this pump/setup is called convertible as I have some sort of cast iron device attached to the pump which has on the front (side attached to the pump) two ports matching these on the pump.

    The back of the "contraption" is clamped with single black plastic pipe (3") going thru the wall in direction of my well.

    Headache started when I connected everything together.
    The new pump come with back pressure regulator, which I installed even I didn't have such thing before.

    Pump primed very well, but cant build more than 30PSI
    None of the adjustment on the back pressure valve or pressure switch did any difference. Also I've noticed that I do not have any water volume in the tank.
    So I figured (wrongly) out, that perhaps my pump would run better on V230
    Right now pump is running on V230, but no changes.
    After further tinkering with pressure switch I decided to eliminate the back pressure valve from the pump and go to old setup without any back pressure valve.

    This helped a little, but still cant get more than 30PSI pressure, however I fill weight of the water in the tank (which was none with the back pressure valve attached).
    This is still less than I used to get.
    I just run outside and tested my setup with garden house. Pressure is there, but after while water from the nozzle started chattering and spitting air. Pressure drops.
    Back in the basement pump kicked is running constantly at 30PSI, agin having same problem with shutoff. Only after easing off the #1 screw it stops, but then my cut-in point drops to 15PSI.

    So right now I am on no more that 30PSI pressure, with small volume of the water (tank supposedly should hold 50 gal.) with need to mechanically disengage the pressure switch.

    Any help will be GREATLY APPRECIATED.
    What did I wrong, and what are my options.
    TG is rains second day here and no need to water the garden.

    And lets keep this between us, no need for Mrs. to know

    Is the jet the old one from the previous pump? I ask because it is a different colour than the pump. Probably the jet is clogged and needs to be cleaned.

    Are you referring to that cast iron device between pump and wall?
    Yes it is old.
    To clean should I take it off the assembly and flush with water or some chemicals. Any movable parts in it?

    Yes, you have to take it off to clean it. I don't have an IPL of your particular jet assembly, but here is one for a Sears pump.

    OK, it doesn't look to sweet.
    I've disassembled the jet from the pump and attempted to move it out from the wall hook-up.
    There is (plastic?) pipe attached to the and of the jet body and somehow loosely attached deep inside that plastic pipe in the wall. I am able to pull this out for 4" and that is all. Didn't force it out as I am afraid to brake that tiny (1"-1 1/4") thin-walled pipe.
    Also I inspected that jet body, and can't see anything inside the casting, except that pipe. No valves, no ventures. Just cast iron body with some cavities inside. As it can be seen from the pics., this is some snob-nosed jet, not the kind shown on the diagram above.

    It's hard to make it out from the small pictures, but that doesn't look like a convertible shallow well jet assembly. It almost looks like a wellhead adapter for a deep well packer jet.

    Here is an IPL of a vertical casing adapter and packer jet.

    My guess is that there is a packer installed into the poly pipe. Reconnect the casing adapter, remove the hose clamp and pull out the nipple to remove it.

    If that would be the case, can I revive (clean) it or it is a replacement part?
    Any idea where should I look for replacement if that would be the case?

    You should be able to clean it. Most any pump supply house would have packers and convertible shallow well jets.

    It is no-go. I pulled the nipple from the pipe, but it stopped after the nipple separated from the pipe, roughly 4". Insight is that darn pipe holding everything together. I tried to gently twist and pull, but is not going well. I am afraid that if I brake anything I would ended up with unearthing that pipe going from inside the basement to the well.
    Any suggestions?

    Wow, that is a strange install. Maybe the packer isn't in that horizontal pipe after all. Maybe the small inside pipe goes all the way down the well and the packer is down the well where it should be.

    How far is the well from the house and does it look like it is a straight shot from that horizontal pipe to the well? What size is the well casing? Is the top of the well sealed tight with that cap? How far below grade is that horizontal pipe?
