Cannot fully tighten shower mount onto shower filter

Last updated on Apr 14, 2026

Shower mount won't fully tighten onto the shower filter

Some shower mounts and shower heads have a raised collar or protruding edge around their threaded connection. When this sits against the body of the shower filter, it creates a gap that prevents the connection from tightening fully — and allows water to leak from the joint.

This is a known compatibility issue, and we've developed a simple solution: a small threaded adapter that bridges the gap and allows the connection to seat properly.

****Shower Filter Adapter

The adapter should be included in the box with your aquabliss shower filter. If yours didn't come with one, contact us and we'll send one out to you free of charge.

How to install the adapter

The adapter installs between the shower filter outlet and the shower head or mount. Follow these steps:

  1. Attach the adapter to the threaded outlet at the bottom of the shower filter (the end that connects to your shower head or mount). Before threading it on, check that there is a washer inside the adapter — this is needed to seal the connection. Hand-tighten the adapter onto the filter.

  2. Attach your shower mount or shower head directly onto the other end of the adapter. Again, make sure there is a washer inside this connection before threading it on. Hand-tighten until firm.

Turn on the water and check both connection points for leaks. If you see any dripping, add a layer or two of plumber's tape to the relevant threads and reattach.
