Need help figuring out how to rig an expansion tank for my new in the well pump, from using my broken old well pump parts/tank? I bought the in the well pump from Lowes

http://www.lowes.com/lowes/lkn?action=productDetail&productId=189222-48284-57411-LWS1&lpage=none


And the old well pump I bought from Harbor freight at

If these links don't work, I have saved everything onto a microsoft word page and can forward it to your direct e-mail, just PM me and I'll be glad to. It's getting hot out and I'd really like to use my auto floats on my livestock tanks to make sure the water is topped-off.

Thanks for you help. Oh, and I'm really bad at fixing wells, so please make it a detailed instructions.....

waterline coming out of the well goes into the pressure tank, the electircal lines hook into a relay and pressure switch..... and that would be the simplified version if i aint missing something.....

however you might want to get a bigger tank for the reason of eventually you will burn out the relay and or the pump motor and depending upon how deep your pump sits at it can be a bugger to pull it and the pipes up just to replace it for the on/off that happens all to often with a small tank.....

That tank is waaay too small for a submersible pump. You need at least a 19-gallon tank, and mine is 50 gallons. The bigger you can afford to get, the better. A 19-gallon diaphragm pressure tank is $125 new here. A 50 gallon is $260.

The 50 gallon will cycle your pump a lot less than the 19 gallon will, and provides smoother pressure.

You can get them up to 85 gallons.

Look here for examples: http://www.tractorsupply.com/detail.asp?pcID=4&paID=1035&sonID=401&page=1&productID=29647

You'll also have to buy a brass T fitting into which the regulator screws and a pressure gauge.

Buy the largest tank your budget will permit. Put a low pressure cut out type switch on the pump instead of the common pressure switch. It could save your submersible pump.
