Questions & Answers

What general maintenance tips do you have for U series filters?
Why isn’t the spray bar or bottom outlet of my U series filter producing bubbles?

The venturi air valve only operates on the top outlet of the filter.

Why will my U Series filter not restart after maintenance?

The impeller assembly may be dirty. Detach the motor, pull out the impeller, and clean it and the impeller well. Also inspect the impeller for long-term wear, as it operates 24 hours/day and does require periodic replacement.
