    As I said. I have the entire thing apart. There is no blockage. In a post above I mentioned I am in SC. An hour or so SW of Myrtle Beach. I am pulling pump back out tomorrow.

    You said its a DEEP well and then the pump is at 30 feet - what is that about? You should have bench [barrel] tested the pump before reinstallation on PE pipe. Learn how to assemble PE correctly before doing it - LONG brass or SS barbs with 2 or 3 not chinese clamps per joint, warm the pipe with hot water not a torch. You said the pump was tight on the wires and rope ..... no no no no no. Loosen it up to hang on the PE. That brand pump is poor quality, but likely has a Franklin motor that is good. You might re-use the motor and just buy a good pump head.

    If your pump is at 30 feet, is it deep enough? I live about 100 miles from you and I, like you, I(I think) get my water from the floridan aquifer. My pump is about 130 feet down and I think the well is about 3 or 4 hundred feet deep total. I know the aquifer depth varies a lot, but 30 feet doesn't sound deep enough to me. Have you tried to determine the water level?

    I agree as to 30 feet. That is what we inherited from previous owner. I am looking into possibly dropping the pump further in. To try and get an idea of the true depth of the well....Can I use a heavy plumb bob, and lower it thru the casing to guage the depth?

    Thanks for the info on PE fittings. Really! That is the kind of support that really helps. So thread a long brass fitting into pump, and the use high quality clamps (at least 2) connected to PE. Got it.
    How about a link to a supplier of PE so I can actually see it. I have run across more PEX than PE in my searches (at least when searching for 1-1/4"). Or; is PEX the same thing, basically?

    I might just use 1".
    My local h'ware store has 1" blue PEX "potable" Can I bury blue PEX?

    How about a link to a supplier of pump replacement? I apologize to Terry if posting links are against the rules. In that case, please disregard the link request. I wil be searching "grainger" etc, this evening due to your info. Now I know what to shop for.

    And lastly; I realize you are right about the cable tension. It probably isn't as tight as I made out originally. My fault. thanks again, and to all the good folks who have added .02-.03 cents worth. Thanks

    I did actually realize that it might be a good idea to guage the well. As long as I am replacing the guts, I might as well upgrade to current methods, and try to drop the pump deeper.

    Good news. The pump I pulled out when the threaded pvc broke off a few years ago ("Aermotor" brand), causing me to replace the pump with the current (Flotec) on bad advice...Tested good today. So at least I don't have to buy a pump as long as this one lasts. I think I still want to drop pump a bit deeper though.

    Thanks again, and to all the good folks who have contributed. Thanks

    You should check for PE pipe with pump supply houses in your yellow pages under the heading Pumps. PE is pipe size meaning the ID is maintained where PEX is CTS (copper tubing size) where to OD is maintained meaning the ID is smaller than IPS (iron pipe size) pipe. PEX is not a good choice for drop pipe or underground from the well to the house. PE has been used for both for over 50 years and will be less expensive while I don't think you can buy PEX in as large rolls as PE pipe.

    Since the inlet to the pump is at 30' or so, all the water under the pump is useless and, if you pull the water down to 30', the pump runs dry, so you're out of water until the well recovers some and that is no good for a pump and a pump with a thermal overload feature will shut it off until it cools and comes back on. Making you think there is something wrong with the pump etc..

    This is my 3rd attempt to post this. software has deleted my last 2 posts. Not very happy about that. So this is a condensed version :)

    I found all supplies except brass barb fittings. I did find gray PVC fittings.

    So I am going to use gray PVC fitting in pump to 1"PE clamped with 3 (non chinese) stainless hose clamps. thru new well cap, and adapting to old manifold. On outlet, they used 3/4" PVC. I am scrapping the entire run and adapting 1" PE to the house. Sound right?

    As for well depth. I spoke with the son of the man who installed the well 15 years ago. The well was originally a shallow well. The drop pipe length is odd in his opinion. We figure that when the well was drilled to a deep well the owners didn't want to replace the casing, and in this area you cannot drop the pump past the casing or you will find sand and debris. That might be the reason the pump is only 30' deep. Our water level is approx. 7-8' below the ground. so I am well below the water level, just not into the sand. I am going to plumb bob for depth tomorrow when I pull pump rigging back out.

    Grainger sells stainless steel hose barb fittings in all the common sizes. Remember that the pump (torquing motion) and pipe full of water (weight) will hopefully be hanging off this pipe assembly for many years. I wouldn't take any chances with plastic fittings.

    Don't use PVC or Nylon adapters or fittings. You can get brass or stainless steel from a plumbing supply house.

    I wanted to go to a plumbing supply house, but the round trip is 3 hours give or take. I have to have this finished tomorrow evening. I might try to get to Grainger. It is a little closer. I really do believe you 2, but the local guy still uses PVC. He liked the idea of going to PE instead of schedule 80, but said he would still use PVC fittings.

    One question just for clarification, or to make sense of this. If schedule 80 PVC with threads can be used, then why wouldn't the PVC barb fitting work as well? Just for closure. Perhaps it is not as thick walled>?

    You all are great to keep up with all this. Thanks

    You cannot use those 39 cent pvc fittings vertically. You need a Graingers stock number 5ym18 brass hose barb with rope fitting [or another without the rope hole] Go to 5YM18 item numbers page and you will see the sort of fittings you need. You must use a TURNED, machined barb if you like your pump to stay on the pipe. The machining provides a "fish hook" rather than the injection moulded junk that is softer than the pipe and without any bite.

    Although I agree with not using plastic or nylon fittings on drop pipe, I have never seen a sch 80 PVC insert or other type fitting that is not harder than PE pipe. And I've never seen any fish hook like barbs and I've worked with a lot of insert/barbed fittings in PE pipe to 500' deep.

    I do not suggest a safety rope. They usually break just when you need one and it wants to fall down the well when they break and that can cause the pump to not come out of the well. That gets expensive real quick if you can't get the pump out.

    Well it is done. I wish you had posted yesterday Gary. I had to run all the way to Charleston to find 1-1/4 brass fitting. It took me stopping 4 places to try and get PE pipe. The Plumbing supply in Charleston, sold out of 1" PE 160 psi before I got there. So I had to chase that down to a mobile home, 'doit best" hardware store,and had to settle for 100psi PE. they are getting me some 160psi, but I might let her fly with the 100psi.
    So there was 1 place in the entire eastern 1/2 of the state that had a 1-1/4 brass fitting to a 1" barb. Guess what!? After removing the bushing that had been used with the schedule 80 (bushing was nylon btw, and hadn't failed in 15 years) I grabbed my 4 hours of driving brass fitting to find that the outlet on my "aermotor" pump was 1-1/2". So I put the 1-1/2" nylon bushing back in the pump and inserted a galvanized 1" to barb fitting that I bought as a back up. Thanks God I bought that backup!

    So new PE pipe, new galvanized fittings, spliced with an underground butt connected with shrink wrap and a double coating of Scotch super33, new well cap, and we have water again.

    The only problem now is that the pressure switch is cutting on and off too quickly. My man at the Plumbing supply stated I needed pump to run for a minimum of 1 minute. Pump goes on for about 15 seconds and cuts off. I know that is bad. I am looking up the directions for adjusting the pressure switch, and I am going to run a pressure test on the tank; but tomorrow. I am sick, and have had enough of sweating in the cold for today. Hopefully the system won't take a dump before tomorrow. Thanks Good Folks of TerryLove.com DIY forums.

    I hope you hung it all at 30 feet again, otherwise the nylon bushing will be your next failure, and after that goes the galv. chinese barb. Why not Graingers instead of 4 hours driving? GS:I dont fish with my barb fittings, but a machined fitting has bite.

    You should check the pressure switch but the tank itself is more likely the problem. If you have a bladder type tank the pressure ( pump off, tank pressure drained) needs to be 2lbs less than the pump cut in. You may have a bad tank also. If you get water out of the air valve the bladder is gone.

    I forget what size pump you have but it's probably a 1/2 hp so I don't think the nylon fitting is a problem at 30'.

    The galvanized needs to go though, it will rust adding iron to your water.

    The 100 psi should be OK at 30' but I would use at least 125 psi but 160 is best.

    The PE and nylon will probably go forever unless the pump gets hot from no water etc..

    What that guy meant about the pump running for a minute has nothing to do with the switch, it is the size of the pressure tank and the draw down gallons between pump runs. The pump should stay off for a minute (60 seconds off) so the motor can cool before running again. Less than that and the pump short cycles, and too little air pressure in the tank can cause that too. So 1-2 psi less air than the cutin setting of the switch. 30/50 gets 29-28 psi with no water in the tank.

    I did not have time to wait on grainger to order the part. I had no water for days, while researching how to correctly upgrade my well. Everything is working great. Like I said if you read my post. Roland Supply was the "only" place that had a fitting I could use "TODAY!" All quality parts. Not chinese. All well diggers, and commercial plumbers shop at the store Roland Supply for all their plumbing hardware.

    I am not an idiot. Of course I hung the pump in the same spot, inside the casing. I have been a contractor all my life. I merely wanted good advice from knowledgable people, and I got it here. I needed the job done, and I have water. I am not a puss, and can handle pulling the dadgum thing out again once I can get the correct brass fittings. Sorry I did not do it exactly as you recommended. My wife really enjoyed her shower last night.

    Thanks for your input. :)

    I knew that Gary, thanks. I set my pressure switch last night, and I have better pressure than before, there is absolutely nothing wrong with the bladder tank...So far (fingers crossed). It wouldn't surprise me if something else (the tank) failed just because I replaced a big portion of the system with new stuff. Just like when you fix your car. Fix one thing, something else breaks...hope not. Later

    Plan on getting the brass. Also; The store where I got the 100psi is getting 160psi within the week. plan on getting a roll of that, asap.

    After adjusting. With the tub faucet running full blast my cycle is almost 2 minute off, allowing for the bladder tank to function correctly utilizing most of the stored water before pump cuts on. I am very happy with the performance of the well now. Will let you know if anything comes apart; Just for the reference.

    Thanks all. Roger
