What Glacier Bay has confirmed (Home Depot Q&A)
- Reversible: asked whether the cartridge can be flipped to fix hot and cold lines piped backward, Glacier Bay answered "The cartridge can be flipped."
- Not for H40621B: Glacier Bay said it isn't compatible with that model.
- For models not on the list, Glacier Bay refers shoppers to Home Depot customer service (1-855-434-5224).
How to recognize it
- Beige ABS plastic body. Home Depot lists it at 3.05 in high and 1.57 in wide.
- It's a single-handle tub/shower cartridge. The listing doesn't say whether it's pressure-balancing, so check your faucet manual.
Hard water
Several reviewers in hard-water areas say they replace this cartridge every few years because of mineral build-up. If a new one gets stiff quickly, that's the likely cause, not a bad part.
