Function For your home pool and spa maintenance and upgrades, replace broken manifold components to restore heater efficiency and enjoy your pool or spa. Superior Replacement Fits most sizes Pentair MasterTemp 175, 200, 250, 300, 400 and the Sta-Rite Max-e-Therm SR200, SR333, SR400. Our manifold does NOT fit the 125. The 125 or 125000 is Pentair’s smallest pool or spa heater. The 125 needs to use a smaller manifold.
