As a plumbing expert with years of experience in dealing with various bathroom fixtures, I can provide a comprehensive explanation for the issue you're facing with your toilet. The necessity to hold the handle down to flush the toilet is a common problem that can be attributed to a few different factors. Let's delve into the mechanics of a toilet to understand why this happens and how it can be resolved.

Toilets operate on a system of water flow and siphoning. When you flush, the water from the tank rushes into the bowl, creating a siphon that pulls the waste out and refills the bowl with clean water. The key component that controls this water flow is the flapper or flush valve. It's connected to the flush lever by a chain or lift wire. The chain's purpose is to lift the flapper, allowing water to flow from the tank into the bowl.

The primary reason for needing to hold the handle down is often excessive slack in the lifting chain. When the chain is too loose, it doesn't provide enough tension to fully lift the flapper, which means the water doesn't flow freely. As a result, the toilet doesn't flush completely, and you have to hold the handle down to ensure the flapper is lifted high enough for the water to pass through.

Here are the steps to diagnose and fix this issue:


1. Inspect the Chain: Check the length of the chain connecting the flush lever to the flapper. There should be minimal slack—just enough for the flapper to move freely but not so much that it doesn't lift properly.


2. Adjust the Chain Length: If the chain is too long, you can adjust it by shortening it. This can usually be done by detaching the clip that holds the chain to the flush lever and moving it up the chain to reduce the length.


3. Check the Flapper: Sometimes, the flapper itself can be the issue. If it's worn out or damaged, it may not seal properly, causing the toilet to run continuously and not flush correctly.


4. Replace the Flapper: If the flapper is the problem, replacing it with a new one can solve the issue. Make sure to choose a flapper that's compatible with your toilet model.

5. **Inspect the Flush Lever and Associated Parts**: The flush lever and other parts of the toilet tank mechanism should also be inspected for any signs of wear or damage that could affect their operation.


6. Test the Toilet: After making adjustments or replacements, test the toilet by flushing it to see if the issue is resolved.

Remember, working with water systems can be tricky, and if you're not comfortable doing these adjustments yourself, it's always best to call a professional plumber to avoid any potential damage or leaks.

Now, let's move on to the translation of the above explanation.
