We presume that the system you got from Baileys has a 4040 r/o @Amos.

You need to take a reading of your tap water and then a reading of the pure water coming out from the r/o BEFORE the di vessel. That will tell you the state of your membrane.

If the membrane isn't working efficiently then your resin use will increase.

 
As @doug atkinson says, its your membranes that are causing high resin use.

When you are purifying water how much waste do you have to the amount of pure you produce? Is it 1 liter of waste to 1 liter of pure for example?

When did you last change your carbon filter?

 
I like MB 115 tulsion , its a good quality ! Heard bad things about unger though ... i dont know how much you fill your resin vessel but ive had good exp. In not filling higher than to where it starts to bend at the top.

 
Can you do a side view as well as looking at that photo I don't know if your waste bottom and pure top are joined together. On the photo it looks like it but may be wrong
