Hi, I am having trouble identifying the multi port on my older Triton II filter (clear top). The port is on the side of filter and the pipes are 2". The number on the housing is SP-715-A-6 and when I search this number it comes up under Hayward products but also shows under Sta-Rite. But the top of the unit is PacFab. The glass sight cracked and the gasket is worn out and broken off and needs to be replaced. This is so confusing.
