When DI resin is spent, does it start to dump the dirt back into the water?

Reason I ask is that I've just discovered the TDS of my water coming out of my RO reading 014ppm but then comming out of my DI canister reading 026ppm.

Have changed the resin and it's back to 000ppm.

Strange or what!

yeah it must do - i've noticed the same thing before - from ro 4ppm from di 9ppm
