My tap TDS is 60.

Im using 1 DI vessel at the minute.

Whats the idea behind using 2 vessels to save resin?

Is it worth it?


My vessel is starting to creep up to 001, so ive got 3 months out of it.

Cheers

Use your old vessel ( which is filtering at 001 ) as a pre filter to adding a new one, so the new vessel and resin will last longer as it is not working so hard.

When your tds creeps up again, then change the resin from number one vessel ( the original ) and place this as number two vessel.
