Swimming Pool Filter FAQ

Swimming pool filters can be complex, or at least seem that way, and there always seems to be a bunch of questions regarding the use, care, and cleaning of filters.

There are probably too many pool filter questions to answer in just one blog post.

But, today you're going to learn the answers to three of the most common questions I see regarding pool filters.

SWIMMING POOL FILTER FAQ

1. How often should I backwash?

Truth be told, it depends.

It depends on how much the pool is being used and how dirty it gets during normal use. The general rule for sand filters is to backwash once each month and to tear down twice each year. For DE filters, both procedures should be completed six times per year or more.

2. Why is there dirt flowing back into my pool?

Frankly, it's usually because of poor assembly after a cleaning or a torn grid.

First off, de-assemble your filter and check everything. Put the filter back together carefully and start using it again. Watch it for a week or two to make sure it's working properly.

3. Which filter is best?

A better question... is there a "best" filter? This is subject to debate and my purpose in this blog post is not to do product reviews.

With that all said, all filters will generally do a good job of keeping your pool clean. Most importantly, remember to stay committed to a consistent schedule of cleaning and to size your filter correctly.

Filter cartridges have a reputation of being easy to maintain, and this has been the case for me for many years. However, if you have a large pool that rivals something William Randolph Hearst had then a cartridge filter may not work for such a big pool.

So using a filter that is compatible with your pool size is always a good idea.

Know your pool, enjoy your pool. Good luck!
