Ideal Standard Toilet Flush Problems

An increasingly common issue among modern press-button type toilets is that water continuously runs into the bowl post-flush. This problem can cause significant inconvenience and increase water bills if not promptly addressed. This article sheds light on the potential reasons and offers solutions to mitigate the issue.

1. Symptoms:

• A consistent stream of water running into the toilet bowl after flushing.
• The issue isn’t present at the outset but arises suddenly.

2. Identifying the Issue:
To understand the root cause, you need to check the cistern, where you’ll typically find identification numbers (such as E752 and E6541). These numbers can help in understanding the model type, which is crucial for acquiring replacement parts.

3. Potential Causes and Solutions:

a) Fill Valve Issues:

• Symptom: Continuous water inflow even when the float is manually lifted.
• Solution: The fill valve washer could have deteriorated, or there could be debris preventing it from sealing. The washer is typically located beneath the large round plastic nut atop the valve. Replacements can be found in hardware stores.
• If replacing the washer does not resolve the issue, you might need to install a new fill valve. Prices are typically around £10, and the installation process is straightforward if you’re able to shut off the toilet’s water supply.

b) Misaligned or Faulty Shut-off Washer:

• Symptom: Constant water flow, regardless of float position.
• Solution: Examine the rubber shut-off washer to ensure it’s correctly aligned. If installed inversely, it may not seal properly, leading to water leakage. Reorient the washer and check for improvements.

c) Incorrectly Set Fill Valve:

• Symptom: Persistent water inflow despite a new fill valve installation.
• Solution: Ensure the fill valve is set to the right height and that all washers are in their appropriate positions. If the issue persists, consider consulting the installation guide or seeking professional assistance.

d) Valve Compatibility and Material:

• Symptom: Replacement valves not halting water inflow.
• Solution: Not all replacement valves may be compatible with the toilet model. It’s essential to check compatibility before purchase. Additionally, consider using valves with brass threads instead of plastic, as the latter can sometimes present issues.

4. Expert Recommendations:

• Before disassembling any components, it’s helpful to record or photograph the process. This way, reassembly becomes easier.
• Fluidmaster is a widely recommended brand for toilet fill valves, renowned for its brass thread construction, which offers more durability than plastic alternatives.
• It’s crucial to ensure that the connecting thread of the replacement valve matches the original. In some cases, thread lengths may differ, which can complicate installation.

5. Conclusion:
Addressing a constantly running toilet is not only beneficial for reducing water wastage but also for avoiding inflated water bills. By identifying the root cause and implementing the appropriate solution, homeowners can swiftly remedy this problem. If the issue persists despite trying the mentioned solutions, it might be time to consult with a plumbing professional.
