Frequently Asked Questions (FAQs)
1. Are all dual flush valves the same?
No, not all dual flush valves are the same. Some dual flush valves are operated with a handle, where pushing up gives a half flush and pushing down gives a full flush. Others work with a double button, where one button triggers a half flush and the other triggers a full flush. The design and operation of dual flush valves can vary.
2. What is the common problem with dual flush toilets?
Common problems with dual flush toilets include water continuously running, clogging and leaks, fill valve issues, and water level problems in the toilet bowl or tank. It's also important to consider plumbing compatibility when dealing with dual flush toilets.
3. Why is my dual flush toilet not flushing properly?
If your dual flush toilet is not flushing properly, it could be due to various reasons. Common causes include a clog in the trap, a worn-out flapper, blocked rim jets, a faulty float, or issues with the handle and chain. It's important to identify the specific issue to troubleshoot and fix the flushing problem.
4. How do I know which flush valve to buy?
To determine which flush valve to buy, you can look at the size of the flush valve drain opening in the bottom of the tank. If it's about the size of an orange or baseball, you need a 2-inch seal.
