yeah, if the pressure returns with the head off and you still have pressure issues elsewhere in the house then you have sediment that has lodged in all of your various outlets. This can be a one time deal or it can be a disintegrating dip tube. You can clean out each outlet (the little screen on faucets and such) and hope the problem is gone but if it's the dip tube it will come back eventually.
