The installation is so simple that you can do it on your own following the instructions in the manual. The included wrench facilitates the replacement, installation, and related processes.
Why does water leak from the housing connection?
The O-ring may not be in place or there is not enough Teflon tape on the thread. Please reapply the Teflon tape and tighten it. If it still leaks after adjusting the O-ring or threads, please contact our customer service.
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.
