Sand filters - is bigger, better?

[milbogo]

Hi guys, being new to pools and to this forum - this is what I learn so far in terms of having an efficient setup (keeping power bills down):

PUMP- bigger isn't better. Get the right size pump, or slower running pump - running longer is better.
PIPES - Bigger diameter is generally better.
CHLORINATOR - Getting bigger than what you need is better, you can run chlorinator shorter times - less wear on cell - cell will last longer.
SAND FILTER?????

Is a sand filer bigger than what you need better? ie will a bigger pump cause less friction and be more efficient?

The answer is the missing link to my basic knowledge of pool equipment and efficiency

You have to have the ability to backwash the sand filter at the proper rate- backwashing too fast or too slow will cause problems.

As cprince eluded to, the ability to backwash properly is the deciding factor. Each filter size has a recommended backwash flow. As long as your pump is capable of producing that much flow, you're fine.
I don't ever remember someone who had a pump large enough to cause a too much backwash issue. However, I'm sure there are setups out there that could.
