FAQ

Can I skip soaking the new filter?

No. The matching PDF instructions say to soak the new main filter for five minutes before installation and rinse it before use.

Should I soak the filter inside the fountain tank?

No. Use a separate clean bowl or container so loose filter dust is not introduced into the fountain tank.

What should I check if water flow is weak after replacement?

Check that the filter, cover or lid, water pipe, tray, pump area, and tank are seated correctly for your model.
