Thetford C200 Toilet Manual Flush Problems
The Thetford C200 toilet is a common choice for caravan enthusiasts, renowned for its functionality and design. However, like all systems, it’s not without its quirks. Some owners have reported manual flush problems, mainly related to unexpected water accumulation in the toilet bowl. This article aims to shed light on this issue and provide potential solutions for those facing similar problems.
1. The Issue:
Owners of caravans equipped with the Thetford C200 toilet, especially those with models like the Swift 2003, have noted an unusual problem. Despite ensuring that the electric flush had stopped and there was no evident leak, they sometimes returned to find the toilet bowl filled with fresh water, alarmingly close to overflowing.
2. Potential Causes:
- A malfunctioning or worn-out seal could be the culprit.
- The electric motor valve might be faulty or malfunctioning.
- Dirty contacts on the electric flush button might be causing unintentional flush operation.
- Misplacement or breakage of the brackets holding the electric pump in position, leading to a siphon effect.
Solutions and Remedies:
- Consult with Thetford: Before attempting any fixes, it’s a good idea to consult with Thetford directly. They are often knowledgeable about common problems and can provide specific advice. In some cases, they have identified a powdered valve deep in the system that might fail and allow for unexpected filling. Replacing this valve has resolved the problem for some users.
- Inspect the Electric Motor Valve: If you’re comfortable with DIY fixes, consider inspecting the electric motor valve. Faults or malfunctions in this component could be responsible for the unexpected filling of the toilet bowl.
- Check and Clean the Electric Flush Button: The electric flush button’s dirty contacts could be causing unintentional operation. Cleaning these contacts can potentially resolve the problem. However, it’s crucial to ensure the cleaning process is thorough to prevent recurrence.
- Inspect the Fresh Water Tank Positioning: One owner found that the two plastic brackets meant to keep the electric pump and valve upright had broken. This misplacement could lead to a siphon effect, causing the toilet to fill. Fixing the pump’s positioning using plastic cable ties or replacing the broken brackets can solve this issue.
- Conversion Kits: For those interested in converting a manual flush toilet to an electric one, it’s advisable to check with Thetford or trusted caravan equipment dealers. They might have conversion kits suitable for specific models like the Thetford Model Cassette PPC4r No 1634 26Z GO7.
Conclusion:
The Thetford C200 toilet is an integral part of many caravans, and while its design is generally reliable, unexpected problems can arise. Through a mix of regular maintenance, prompt consultation with experts, and sometimes a bit of DIY, owners can ensure their toilet system remains functional and trouble-free. If problems persist, it’s always best to consult with a professional or the manufacturer.
