I'm trying to track down a suction side leak, and one of the possibilities is an older Purex Ortega 3 port valve. I know that I can replace and re-lube o-rings and/or other seals in this unit, but before I start I'd like to get as much information as I can so there aren't any surprises when I take it apart. I found some exploded views online, but it would be nice if I could find a manual or some actual instructions indicating any special order of steps involved, what to lube, what to replace, and what not to mess with. Unfortunately, this is an older valve, and I was not able to find any information for it on the Pentair site. I'm a little concerned that taking it apart could cause some parts to disintegrate, so I'd like to know what I'm potentially dealing with before I start, and if the parts are commonly available.
Does anyone know of where I could find a manual or maintenance instructions for this valve?
Also, is there any sort of "rebuild kit" available for this valve that's designed for general maintenance? All I find online are full parts lists.
