Small pressure tank on Neighborhood well

So I live in a neighborhood with a shared well (60+ homes) my house has 1/2 copper throughout and I'm looking for a way to boost the pressure, just a little.... Will adding a pre-charged or regular pressure tank (20gal) give me a pressure boost... at least enough to regulate and maybe take out air pockets.... And how easy are they to plumb in... Thanks

A pressure tank only stores pressure, it can't boost pressure. You will need a booster pump, then a small pressure tank with a pressure switch. However, if you have "air pockets" it will cause problems for a booster pump. Sounds like the main pump system needs some work. Need to figure out where the air is coming from and increase the pressure at the main pump system.
