2319 Replacement with PS #7943
Controller # 2319 is obsolete. This is a kit to replace that controller. If the pressure switch you have looks like the one pictured (#2047) you do not have to replace your pressure switch. You can purchase kit #7942 without pressure switch. If the pressure switch you have is longer and skinnier, than you do have to replace it and you want to purchase kit #7943 with pressure switch.
