A toilet that keeps running can be a major annoyance and a significant waste of water. The issue is commonly caused by problems with either the fill valve or the flush valve. These are tank components and understanding how they work and how to replace them can save you money and reduce water waste. This blog post will guide you through diagnosing the problem, explain how to fix it, and discuss the cost and complexity differences between replacing fill valves and flush valves.
Diagnosing the Problem
When a toilet continues to run, it’s often due to one of the following issues:
1. Fill Valve Issues: The fill valve controls the water level in the toilet tank. If it’s malfunctioning, it might allow water to continue flowing into the tank, which then spills into the overflow tube and causes continuous running.
2. Flush Valve Issues: The flush valve controls the release of water from the tank into the bowl during a flush. A faulty flush valve can cause water to leak continuously from the tank into the bowl.
Replacing the Fill Valve
Fill valves are typically easier and cheaper to replace than flush valves. Here’s a step-by-step guide:
1. Turn off the water supply to the toilet and flush it to drain the tank.
2. Remove the old fill valve by disconnecting the water supply line and unscrewing the lock nut that holds the valve in place.
3. Install the new fill valve according to the manufacturer’s instructions. Make sure the new valve is adjusted to the correct height.
4. Reconnect the water supply and turn the water back on. Check for leaks and adjust the fill valve as necessary.
The cost of a new fill valve ranges from $10 to $20, making this a cost-effective repair.
Replacing the Flush Valve
Replacing the flush valve is more complex and costly. Here’s how to do it:
1. Turn off the water supply and flush the toilet to empty the tank.
2. Remove the tank from the bowl by unscrewing the bolts that hold it in place. This step can be tricky and might require a second person.
3. Remove the old flush valve by unscrewing the lock nut and taking out the valve assembly.
4. Install the new flush valve by following the manufacturer’s instructions. Make sure all seals are tight to prevent leaks.
5. Reattach the tank to the bowl and reconnect the water supply.
Flush valve kits typically cost between $20 and $30, but the labor involved can make this repair more expensive. If you hire a professional, the cost can sometimes exceed the price of replacing the entire toilet.
Handyman vs. Professional Plumber
While these repairs can be handled by a handyman, they can also be done by a homeowner with some basic DIY skills. Hiring a handyman can save you money compared to hiring a professional plumber. However, for more complex issues or if you’re not comfortable doing the repairs yourself, it’s best to consult a professional.
So Fixing a toilet that keeps running involves identifying whether the problem is with the fill valve or the flush valve. Fill valves are generally easier and cheaper to replace, while flush valve replacements are more labor-intensive and costly. A handyman can handle these repairs, offering a cost-effective solution. Addressing these issues promptly can save water and reduce your utility bills.
By understanding the differences between fill and flush valves, and knowing how to replace them, you can maintain your toilet's functionality and efficiency without breaking the bank.
