1. Loose Connections
Your toilet refill hose will keep popping out if it is not properly connected to the fill valve or the overflow tube. For instance, if your refill hose has threaded fittings but aren’t tightened enough, they can easily come loose due to water pressure or movements in the plumbing system.
Moreover, the seals or washers within the fittings can degrade over time due to regular use, leading to leaks and a loose connection. In addition, the connections can loosen over time due to vibrations in the plumbing system or any movement of the toilet.
Fix
a) Tighten Fittings
Use your hands to carefully tighten the fittings connecting the hose to the fill valve and overflow tube. If the clip or clamp that attaches the refill hose to the overflow pipe is loose, use a screwdriver or pliers to tighten it gently.
b) Replace Seals or Washers
If you notice worn-out seals or damaged washers, replace them with new ones compatible with your toilet’s fittings.
c) Recheck Installation
Ensure the hose is correctly installed and firmly positioned in the designated connectors. Check the manufacturer’s manual for correct installation.
d) Stabilize the Toilet
If your toilet seems wobbly or unstable, secure it properly to the floor to help prevent vibrations that might contribute to loose connections.
2. High Water Pressure
High water pressure in the plumbing system can also cause the hose to pop out. As water flows through the refill hose with excessive force, the pressure created could push out the hose.
If you suspect elevated water pressure, measure it with a pressure gauge.
Fix
- Install a pressure-reducing valve or regulator in your plumbing system to help regulate and reduce the overall water pressure in your home’s pipes.
- Tighten the fittings, joining the fill valve to the overflow tube. If loosely connected, the refill hose can get disconnected even with normal water pressure.
- Consider using a more robust or reinforced refill hose designed to withstand higher water pressures. These hoses can handle increased pressure without popping out from their connections.
3. Old or Damaged Parts
The hose itself or the components it connects to (such as the fill valve or overflow tube) might be worn out or damaged, causing the hose to slip out. These parts can deteriorate, causing improper fittings and a loose refill hose.
Therefore, when troubleshooting this problem, check the fill valve, overflow tube, and refill hose for signs of wear, cracks, or damage. A worn, stretched, or weakened refill hose is more prone to slipping out.
Furthermore, inspect the seals or washers within the fittings of the refill system since damaged seals can cause leaks and contribute to the hose popping out.
Fix
Replace any worn-out or damaged parts, making sure the replacement parts are compatible with your toilet. For instance, Fluidmaster 218 Toilet Refill Tube and Clip Replacement (View on Amazon) is highly durable, installs easily, and fits most fill valves.
Implement a schedule for checking and maintaining the toilet’s refill system. This will help you catch any signs of wear or damage early and prevent issues like the hose coming loose.
Note
Apart from compatibility, go for durable, high-quality products when choosing replacement components. For instance, stainless steel braided hoses are constructed with a durable stainless steel outer layer, providing exceptional strength and resistance to wear and tear.
Upgraded materials are generally more robust and capable of withstanding varying water pressures and environmental factors without deteriorating quickly. This durability leads to fewer instances of detachment or failure.
4. Length of The Hose
The length of your refill hose can also contribute to it coming out repeatedly. This applies to both long and short refill hoses.
On the one hand, if the refill hose is too short, it might not reach the designated connectors properly. This can cause it to pop out or not fit securely, leading to leaks or detachment.
On the other hand, a hose that is too long can have excess slack, leading to kinks or bends that prevent it from staying in place securely. This might cause the hose to dislodge from its connections.
Fix
If your refill hose is too long or too short, reinstall it according to the manufacturer’s instructions. Make sure it’s not stretched too tightly or excessively loose.
It should have enough slack to reach its connectors without excessive bending or stretching.
Additionally, ensure the hose is correctly positioned without any kinks or bends that might cause it to dislodge from its connections. If necessary, adjust it to eliminate any unnecessary twists or loops.
If the hose is too short or long despite your efforts to adjust it, get a replacement hose of the correct length and type for your toilet model.
5. Incorrect Installation
For a toilet to work flawlessly, the components must be installed correctly. Therefore, if your refill hose is coming out repeatedly, the issue could be due to incorrect installation.
The refill hose might not fit snugly into the connectors if it isn’t appropriately aligned with the fill valve or the overflow tube. This misalignment can cause it to pop out easily.
Moreover, suppose the hose wasn’t securely fastened to the fill valve or overflow tube during installation. In that case, it can easily become dislodged due to water pressure or movements in the plumbing system.
Fix
i) Reinstall the Hose
Turn off the water supply to the toilet and carefully reinstall the refill hose, ensuring it is adequately aligned with the fill valve and the overflow tube. Insert fully and securely into the designated connectors.
Hand-tighten the fittings without over-tightening to avoid damaging the components.
ii) Check for Leaks
After reinstalling and securing the hose, run the water and check for leaks. If leaks persist, reevaluate the installation.
6. Obstructions
Blockage or restriction within the hose or the inlet it attaches to can create pressure imbalances or prevent a secure connection, leading to the hose popping out. Therefore, ensure both the hose and the inlet are free from debris or blockages.
Fix
Disconnect the refill hose from the system and use a garden hose or another water source to flush out any debris. Exercise caution to avoid damaging the hose while performing this action.
For more stubborn obstructions, use a cleaning tool, such as a thin, flexible wire, to carefully push through and dislodge any blockage.
Furthermore, make sure the point where the hose inlet is also clear of any debris or blockages. Clean the inlet carefully using a small brush or flushing it with water if possible.
If the obstruction is severe or the hose has sustained significant damage, replace the damaged parts or the entire hose.
How To Replace A Refill Hose
Follow these steps to remove an old refill hose, then install a new one.
Things You’ll Need
- New refill hose or tube
- Adjustable wrench or pliers
- Towel or sponge to soak up any water
Steps
- Before replacing your toilet’s refill hose, you’ll need to make sure water doesn’t flow into the toilet and the tank is completely empty.
- Loosen the nuts that connect the refill hose to the toilet’s fill valve and the water supply valve. Turn the nuts counterclockwise to loosen them, then detach the old hose from both connections.
- Pull the old hose out of the tank, then drain any remaining water by holding it over a bucket or tipping it into the bowl.
- Take your new refill hose and connect one end to the fill valve on the bottom of the toilet tank. Hand-tighten the nut onto the fill valve, and then use the wrench or pliers to give it a quarter turn to ensure it’s snug but not over-tightened.
- Attach the other end of the new refill hose to the water supply valve coming out of the wall or floor. Again, hand-tighten the nut onto the valve, then use the wrench or pliers to give it a quarter turn to secure it in place.
- Let the water flow back to your toilet by turning on the shut-off valve. After that, check whether water is leaking between the connections. If necessary, tighten the nuts slightly if needed to stop any leaks.
- If everything looks good, flush the toilet and observe the new hose to ensure it’s working correctly without any leaks.
