I've been looking for a description on how multiport valves work and can only find general overviews. The question of Waste vs Rinse has been bothering me. Can any of the knowledgeable and esteemed members of this board educate me?
When in the "Waste" setting on a multiport valve water flows from the pool, through the pump, and to a Waste port. Simple enough.
"Rinse" is more obscure to me. Let me explain. The filter has two ports, In and Out (when filtering in normal operation). During backwash, water flows from Out to In (backwards) through the filter. "Rinse" is supposed to rinse the filter after backwashing. A proper rinse would require a second In port. Rinsing would have water flow from one In, to the other, and then out to Waste. This is clearly not how Rinse works.
With one In port, all the "Rinse" setting can do is send water by the In port and then to Waste. This seems identical to the "Waste" setting.
What am I missing?
