There have been related threads to this one but replies seem to be mixed so I'm posting this. My well & submersible pump system has two pressure tanks. One is a small 2-gal unit with a pressure switch located in the well pit along with the pump control box. The second one is a 44-gal unit in the house crawl space without any pressure switch. The main water line between well and crawl space is about 100' long, 1-1/4" diameter I believe. There is a check valve just before the tee to the 44-gal tank. My question is whether I need to have an additional pressure switch at the 44-gal tank? Or, should I remove the pressure switch at the 2-gal tank and put it next to the 44-gal tank? (Both options would require some additional wiring that I'd rather not have to do.) I know there will be some pressure drop in the 100' line that some folks have claimed will cause the well pump to cycle on-off again briefly after filling the 2-gal tank. BTW, I do not know why there is such a small pressure tank in the well pit - maybe because that was the largest size that could fit and the 44-gal was added later to reduce cycling? I also know there used to be an AquaGenie flow controller in this system but it has been removed - but not sure if this is relevant. Thanks for any help!
