Why You Might Need to Replace a Toilet Fill Valve
If you’re still on the fence about whether your toilet needs a new fill valve, here are some common signs:
- The toilet keeps running long after flushing
- The tank takes a long time to refill
- Water trickles into the bowl constantly
- Strange hissing or whistling sounds
- Water leaks from under the tank
In Singapore, many older HDB flats and condos have toilet fittings that suffer from mineral buildup or corrosion due to our water quality. This affects the performance of internal components, especially the fill valve. Replacing it isn’t just a fix—it’s a long-term improvement.
Tools and Materials You’ll Need
Before you begin your toilet fill valve replacement, gather these basic items:
- New toilet fill valve (universal or brand-compatible)
- Adjustable wrench or pliers
- Towel or sponge (to catch residual water)
- Bucket (optional, but helpful)
- Gloves (optional for hygiene)
You can find replacement valves at local hardware stores such as Selffix, Horme, or even online platforms like Lazada or Shopee. Just make sure to match the model or choose a universal valve if you’re unsure.
Step-by-Step Guide: How to Replace a Toilet Fill Valve
Step 1: Turn Off the Water Supply
Look behind your toilet for the shut-off valve, which is usually found near the floor. Turn it clockwise to stop water from flowing into the tank. Most of the water can be drained by flushing the toilet. Use a towel or sponge to soak up what’s left in the tank.
Step 2: Disconnect the Water Supply Hose
Use a wrench or your hand to unscrew the hose from the base of the tank. This is the hose that brings water from the supply line to the fill valve.
Step 3: Remove the Old Fill Valve
Inside the tank, you’ll see the fill valve connected through the bottom. There’s a locknut under the tank that secures it in place. Loosen and remove this nut. Once done, lift the old valve out.
If your valve is crusted with mineral deposits or visibly worn out, you’ll be glad you’re replacing it now rather than later.
Step 4: Insert the New Fill Valve
Place the new fill valve into the same opening. Adjust its height according to the tank’s size—most modern valves are adjustable. Lock it in with the nut from underneath. Make sure it’s firmly in place, but don’t overtighten.
Step 5: Reconnect the Water Supply
Screw the hose back onto the new valve. Again, it’s tight but not overly tight. Verify the hose connector’s washer again; it must be in good shape to stop leaks.
Step 6: Turn On the Water Again and Test
Slowly open the shut-off valve. Let the tank fill and watch for leaks around the base of the valve and the hose connection. If everything looks good, test the flush.
Adjust the float if necessary so that your tank stops filling at the proper water level. You’ll usually find a clip or screw adjustment on the valve.
Common Mistakes to Avoid
- Forgetting to turn off the water supply: Always shut off the valve first to avoid flooding.
- Overtightening connections: This can crack plastic parts or strip the threads.
- Using the wrong size fill valve: Match your existing valve or choose an adjustable one for flexibility.
- Not testing for leaks: Always check thoroughly before walking away from the job.
