    You will have to give me a lot more info than that for me to make a call. First of all, you need at least a 3" well to install a submersible pump.

    Do you know where the well is? What size it is? How much it is capable of producing?

    Being in PA you probably have a 6" well. If you have a two line deep well jet pump, your well is probably not more than 150' deep. I've converted a number of them. You may have a pit and if so you need to extend the casing to like a foot above ground, run 230v to the well through the one water line from the well and use the other for the water from the submersible. You will also install a pitless adapter below the frost line. That means you dig down around the casing on the side facing the house large enough to get down in it comfortably to drill/cut the pitless hole etc.. You need to have 6-8" on the backside of the casing. With the right size hole saw for the pitless hole and a good drill or a cutting torch, you can do the pitless hole in the casing very easily, as long as you create enough space in the trench.

    Most any pump guy or driller can do it or if you are handy you could do it if you know how. If you have a single line shallow well jet, you need to run electric to the casing using the old water line as a conduit and installing a new water line or just run the power cable like 18-24" deep.

    Extending the casing can be done with steel or 6" sch 40 PVC and a Fernco fitting and a casing cap. I've done this with the top of the old casing down 8-10 feet; at the basement floor level. That requires a backhoe and a big hole in the yard, no screw ups, 2-3 people and good pre planning. I have pictures.

    Sorry about the lack of info. Yes I have two line well but I have know idea where out in the yard the well is or what the capasity is. I guess I will start to look for a new jet pump.

    You might be able to find out about the well from the people that regulate Well Drillers in your area. Usually the Health Department. If it looks favorable, like you having a 4" or larger well and it making 10 gpm or more a submersible would work fine.

    If your looking for a Jet Pump or Submersible Pump please have a look at these two links. We have great pumps at great prices.

    My advice is to find the well now. You're going to need to get into it sooner or later and how soon depends on how long it has been since it was opened the last time. Also, the j-body of a two line jet is in the well and the foot valve is attached to it. The jet pump and j-body must match or your new pump may not pump too well and you'll be digging up the yard now anyway.

    Rent a metal detector and have a go at finding the pit; you probably will have a metal sanitary seal on the top of the casing in the pit. And if you're lucky, the pit cover won't be more than 2-3' under the grass.

    If that doesn't work, disconnect a line from the pump and run a metal electrical 'fish' out through it as far as it will go and go find that with the detector.

    A foolproof way is a mini excavator or backhoe digging down outside the basement wall where the lines are until you find them and then follow them back out to the pit. If you do that, you should could bury the power cable for the submersible pump in the trench and abandon one of the water lines instead of using it as a conduit which is tough to seal against dirt and water getting in it. Direct buried cable rarely needs to be replaced and then because someone digging damaged it.

    So what is wrong with your jet pump now, it may have something to do with the jet or foot valve in the well?

    Thank you for the info. Nothing is wrong with it just very old " 25+ yrs ". I am about to replace my galv. steel tank with a new bladder tank and thought might as well do both.

    Twenty five years says that now is the time to find the well and go to a submersible and bring the casing up out of the ground.
