Q: Why does water leak from the pressure release button?

The pressure release button has a screw under the bracket. Tighten the screw and this should stop the leak.

Q: Why does water flow slowly immediately after installation?

The filters may be installed incorrectly. Check to see if a piece of the plastic wrapping is still protecting the filter. Likewise, any high-flow situation within the first 72 hours after installation may cause a temporary carbon blockage. To clear the blockage, turn off any running water for at least 10 minutes and resume using water at low or normal flow rates.
