Noticed the past few days my pool was losing water. As my pac fab fns+ 36 is several years old on original parts, I checked the multiport valve and sure enough, set on filter but water was going out the waste line. I turned everything on and capped the waste outlet until the parts get here.
I'm need to double check the model numbers but I'm pretty sure my multiport is the model on the right-

As far as I can tell I need to replace the o-ring part #20 (far left schematic) and the gasket part #2, right?
Will I need any seal or lubricant to install the gasket? This is the correct fix for this issue, right?
