How do you increase water presssure in your house?

the pressure switch by the pressure tank will have two nuts on threaded shafts with springs on them. the bigger one will increase the pressure, both top and bottom. most will have a 20 pound range, which is about right. take a 3/8 deepwell socked, and screw it down, as if you are tightening it, and it will raise it. be carefull not to touch it to anything else while you have it on there. good luck!!

yes there is it is in a little blue or black box it has wires running to it. one little nut holds the cover on. inside you will see a screw about 2 inches long with a spring and washer on it. turn it but pay very close to how many turnes and the direction you turn it so you can put it back to the adjustment if need. also most are out to increase and in to decrease. but you will figure that out. good luck. dont blow any pipes apart making it too high . the system is already used to the working pressure its at now.

Rebuild the pump. if its old youmight replace it.
