Frequently Asked Questions

Q: My toilet won’t fill when I press the pedal. Is this the part I need?
Very likely. A broken or worn valve link is one of the most common causes of lost water flow during flushing.

Q: Does this fit Aqua-Magic IV or Style Series toilets?
No. This link is only for Aqua-Magic V and VI models.

Q: Is this an OEM Thetford part?
Yes — 36528 is the genuine factory replacement.

Q: Will I also need a new water valve?
Not always. If the valve itself leaks or sticks, then yes — but many flush/fill issues are solved by replacing just the link.

Q: Do I need special tools?
No. Basic hand tools are typically all that’s required.
