How to install a shower filter
Short answer: three steps, a few minutes, no tools. Unscrew your shower head, screw on the filter, then screw your shower head onto the filter. Here's the detail.
Before you start
- Lull is made for standard US shower arms and shower heads (1/2-inch thread).
- In the box you'll find Teflon tape and 2 rubber washers.
- Have a towel handy for any drips.
1. Unscrew your shower head
Turn off the water. Unscrew your shower head from the shower arm by hand, turning it counter-clockwise. If it's stuck, wrap it in a towel for grip. Wipe any old tape or grit off the arm's threads.
2. Screw on Lull, then your shower head
If your threads are worn, wrap them 3 to 4 times clockwise with the Teflon tape first. Screw Lull onto the shower arm by hand. Then screw your shower head onto the bottom of Lull. Hand-tight is enough. Over-tightening can crack the plastic or squash the washers.
3. Turn on the water and check for drips
Run the water for a minute. A little grey water at first is normal: that's loose carbon from the new cartridge flushing out. If a connection drips:
- Hand-tighten a little more.
- Add Teflon tape to that thread.
- Check the rubber washer is sitting flat, or swap in a spare.
Troubleshooting
- Lower pressure than before? Normal at first. If it stays low, check the washer isn't blocking the opening.
- Shower head sits too low now? Lull adds a few inches. An adjustable or angled shower arm can help.
- Won't thread on? Your arm may not be a standard US thread. Email us a photo and we'll check.
That's it. Change the cartridge about every 60 days. See how often to change a shower filter.
