Springtech 300 recirculation wash

[village idiot]

On the side of my Springtech RO it shows pictures for the valve positions for concentrating, soap washing, and rinsing. There is also a picture for a "recirculation wash" but there are no instructions on when to do this, why to do this, or how often to do this. Do any of you know? The unit works like a champ but I will soon be putting it to bed for the season and I want to keep treating it well.

I have never done this either......I always do a rinse every night, and a wash every other time I use the RO. For me that works great.....I am thinking this re-circulation wash is perhaps if you are having a lot of mineral build up so pressures are not holding good throughout the season.....but that is just a guess....should call Leader for a more direct answer, but I doubt it's all that important, at least in my situation....
