Frequently Asked Questions

Q: My flush pedal stays down unless I lift it—will this fix it?
Yes. A failed spring cartridge is the most common cause of a pedal not returning.

Q: Does this also fix bowl water not holding?
If the pedal isn’t returning fully, yes—it can prevent the flush ball from sealing.
If the seal is worn, you may also need a bowl seal kit.

Q: Is this an OEM part?
Yes — 385310683 is the genuine factory spring cartridge.

Q: Do I need to remove the toilet to install this?
Usually no; the mechanism is accessible from the side or back.
