The title says, "one pack." are there 2 bags in 1 pack, or will i need to order this twice to refill a dic-20?

Hello, Thank you for your email. If you order a R2-20 that is two bags of resin. One bag for each cartridge. Warm Regards, Josette Shields Customer Concierge Crspotless Water System 858-530-9993

k would like to know home manie car i can wash with this filter

Good morning, Thank you for your question. it is hard to say without knowing what your TDS (Total Dissolved Solids) level is, or what system you have. If you have a DIC-20 you get approximately 300 gallons of water before you have to change out your resin. Again it depends on your water quality. On a average car you use approximately 10 gallons of water or if you have a SUV or a truck you typically use approximately 20 gallons of water for a final rinse only. Since I don't know what your TDS level is I can only give you approximately how much water you might be using for final rinses only. Warm regards, Customer Service Crspotless Water System

Will this work on Model number SM-1?

The SM-1 is the model number of the TDS meter only. If your system has 2 large blue 20" canisters, then yes, this will work.

Anyone know how to regenerate this resin?

Not sure I understand your question. Once the old resin stops working, replace it with new. Screw of the top of white cylinder, dump old resin, clean out cylinder and replace with new. Does that answer your question?
