FAQs & Answers
- What causes a toilet to fill intermittently? An intermittent filling toilet usually indicates a faulty fill valve or a flapper that does not seal properly, causing water to stop and start filling the tank.
- How do I check if my toilet flapper is leaking? Inspect the flapper for any visible cracks or signs of wear, and ensure it seals tightly against the flush valve seat to prevent leaks.
- Can I replace the fill valve myself? Yes, replacing a fill valve is a common DIY repair that typically involves turning off the water supply, removing the old valve, and installing a new one following the manufacturer's instructions.
