I just replaced the bladder tank on my well. It come preset at 38 lbs pressure and I should have lowered it to 28 before I installed it. (my on/off pressures are set to 30/50). But I forgot. I lowered it about 10 lbs but the tank was full when I did it. So I know I can drain it and then set it correctly but how important is this? So far it seems to be working OK. Tanks.
