When recharging DE filters, this item should be used to bypass the TJ16 prefilter during the process of adding DE (Diatomacios Earth) powder to the skimmer. This item allows the TJ16 to be removed from the plumbing and to continue to be able to circulate the pool. This item is not typically needed if a cartridge or sand filter is present.
