Is it worth switching from Sand to Cartridge?

HI all-
I have not been on here much this year, which is a good thing because my pool has been great and no issues. I was checking my water bill (which is $233...ouch....we need rain in San Antonio...) and I noticed they are offering a $250 rebate if you switch from a Sand or DE filter to a Cartridge filter. I assume their interest is in no back washing. I am curious on your opinions on this.

You can see my configuration in my signature. Is it worth spending the money? I do backwash quite a bit in the Spring because of the leaves and pollen are heavy, but during the summer I almost never need to. My pool is clear. I have had no problems with the sand filter. I run my VS pump on the default program that came with it and it keeps it clear. My s200 robot does a great job in picking up dirt. I am not sure what size cartridge filter I would need, or what they cost. A quick search shows prices between $600-$1000.

Thoughts? Thanks in advance...

I suspect you're right about the rebate being related to saving water with a cartridge filter.

I have to agree with the "if it aint broke" way of thinking.
On the other hand, if you think you might recover your investment within 2 or 3 years, then its worth serious consideration.

Not sure about the DE filter because it DOES backwash and I think it may use more water if not the same because DE filters have a backwash sequence to call it completely backwashed prior to replacing the lost DE. Am I missing something here.

Usually these rebates are only valid if the equipment is "professionally" installed. That usually negates any savings from the rebate. Confirm before you proceed!
