Today’s episode is the second in our four-part filter series, and we are talking all about sand filters. We all know what they look like, but do we know exactly how they work and their correct terminology?
Our guests today break down the anatomy of a sand filter, what backwashing is truly intended to do, why the laterals are important and when to change them out, and when and how to do a proper sand change.
To lead our discussion, we have with us Pentair’s Product Manager on filters and valves Frank Swindell and Regional Training Manager Mike Childress.
Our next episode is a primer on DE filters. Stay tuned!
