Shower filter compatibility with non-standard shower arms
The aquabliss shower filter is designed to fit all standard ½ inch threaded shower arms — the most common type in US homes. If your shower setup uses a non-standard arm type, installation may require a small adapter. Here's how to handle the two most common non-standard configurations.
Shower elbow arm
Shower elbows are L-shaped arms that extend from the wall at a right angle, with the outlet pointing straight down or at a sharp angle. Because of the limited clearance between the outlet and the wall, the body of the shower filter cannot be threaded on directly — there simply isn't enough space to rotate it into position.
The solution is a short extension adapter that adds enough clearance for the filter to thread on freely. These adapters are available at most hardware stores and plumbing suppliers, or online.

Install the adapter between the shower elbow outlet and the shower filter inlet. Add plumber's tape to both thread connections before assembling.
Ball joint shower arm
Ball joint shower arms use a rounded ball-and-socket connection at their end rather than a threaded outlet. Because there are no threads, the shower filter cannot be directly attached.
You'll need a thread adapter that fits over the ball joint and provides a standard threaded outlet for the shower filter to connect to. These are available from hardware stores or online.

Cross-threaded connection
If the shower filter thread became cross-threaded during installation — where the threads have not aligned correctly and the filter has been forced — please contact us before attempting to remove or reinstall the filter. We'll help you assess the situation and advise on the safest way to resolve it without damaging the shower arm.
