just installed new pressure switch, gauge, dual whole house filters, to a t off a 90, bottom of t goes to tank, and side goes to softner/house. not sure what mal uction is, but bladder tank is not filling, haven't adjusted anything, pressure switch was preset to 20/40, switch quickly cycles on and off and then trips off when open a valve or anything, not sure what else to put for info, need to get this fixed asap.
