Swap
A fresh cartridge in a few minutes.
By hand, no tools.
-
Take Lull off
Turn off the water, unscrew your shower head, then unscrew Lull from the shower arm.
-
Open it and take out the old cartridge
Hold the bottom half and twist the top counter-clockwise. If you see grit inside, give it a quick rinse.
-
Drop in the new one and close it
Holes side up, toward the shower arm. Make sure the rubber seals sit flat, then twist it closed by hand.
-
Flush, then put it all back
Screw Lull back onto the arm and run the water for about a minute. A little grey water at first is normal. Then put your shower head back on.
