Frequently Asked Questions

Q: Is this spring compatible with other Thetford toilet models?
A: It is designed specifically for the water-valve assemblies used in Aqua-Magic Plus and Style Lite toilets. Other series may use different valve designs.

Q: Can a worn spring cause continuous water flow or leaks?
A: Yes — a weak or broken return spring often fails to close the valve fully, causing slow leaks or continuous flow.

Q: Do I need to replace seals when swapping the spring?
A: Not always. If seals are still in good condition, only the spring needs replacement. Inspect seals during disassembly — replace if cracked or worn.

Q: Is this an OEM Thetford part?
