If you’re dealing with plumbing issues and trying to fix a Toilet Bowl Leak, I’ve been there—and I know exactly how annoying it is. A few years ago, in my old HDB flat in Tampines, I kept noticing a small puddle of water forming around the base of the toilet. I initially blamed it on condensation or splashed water, but the real culprit was a stealthy leak that caused harm to my bathroom tiles.
To help you avoid what I went through, here’s a clear, personalized guide on how to fix a toilet bowl leak in Singapore, including where to get parts and when to call a pro. Therefore, PS Home Maintenance Singapore brings some practical tips for you to fix a toilet bowl teak in Singapore in addition to their professional toilet plumbing, toilet bowl replacement, and furniture assembly & disassembly, and door repair services.
How to Tell if You Have a Toilet Bowl Leak
The initial step consists of learning how to detect the problem. Wet spots usually appear in Singapore due to condensation since the country has a humid climate, but trouble isn’t always detected in these instances. A toilet bowl leak reveals itself when you notice these symptoms:
- Water accumulates at your toilet’s foundation base after each flush.
- A foul odor alongside mold growth becomes noticeable near the toilet area
- Your ear senses a never-ceasing drop of water flowing at a steady pace.
- The water in your tank stays constantly running.
- Increased PUB water bills with no obvious explanation
If you’re nodding your head at any of these, it’s time to fix that toilet bowl leak before it gets worse.
Where’s the Leak Coming From?
Determining the precise location of a leak is what proves most challenging in my experience. These methods helped me pinpoint the exact source of the leak:
1. Leak at the Base
A worn-down wax ring seal typically leads to this problem. A transparent seal connects the toilet to the floor flange. Every time someone flushed my toilet, I saw water leaking through the wax ring. This problem commonly affects residents who live in older HDB or condo units (10+ years or older).
2. Leak Between the Tank and Bowl
The tank-to-bowl gasket failure and rusty bolts lead to this problem. Water dripping below the tank indicates you likely have a tank-to-bowl problem. The Arino and Baron two-piece units, which are found in local hardware stores, commonly experience this problem.
3. Internal Leak (Tank to Bowl)
A running or refilling mechanism points to internal leaking inside the tank because either the flapper valve fails to seal or the fill valve needs replacement. My flapper valve required replacement, so I got a universal kit from Self-Fix at IMM, which fixed the issue in less than 20 minutes and cost under $15.
Step-by-Step: How to Fix a Toilet Bowl Leaking
Step 1: Cut Off the Water Supply
Switch the angle valve, which typically resides on the toilet wall by the left side, and change its direction clockwise to stop water flow.
Step 2: Drain the Tank
Use a sponge or cloth to dry up the remaining water in the tank after you flush it. The tank should be completely dry before you begin replacing parts inside.
Step 3: Replace the Faulty Parts
Fixing a Leak at the Base:
- Remove the nuts attaching the toilet to the floor.
- Gently rock the toilet bowl to break the seal and lift it off.
- Scrape away the old wax ring and install a new wax seal (available at places like Home Hardware or even Lazada SG).
- Reseat the toilet, bolt it down evenly, and test.
Fix Leak From Toilet Tank to Bowl:
- Use a spanner to unscrew the tank bolts.
- Take out the worn rubber gasket and wearers to replace them.
- Secure the bolts together smoothly to prevent stress cracks.
Fixing a Tank Leak (Flapper or Fill Valve):
- Remove the faulty flapper or fill the valve.
- Put on a new flapper that works with all tanks.
- Adjust the float height if necessary.
Step 4: Turn the Water Back On
Slowly turn the valve back on. Let the tank fill, then flush and check for leaks. I always lay down a few sheets of tissue paper around the base and under the tank to easily spot any new drips.
When You Should Call a Plumber
Sometimes, the leak isn’t obvious, or the fittings are corroded. In one of my jobs in a Jurong West condo, I encountered a hairline crack in the porcelain that was almost invisible until it worsened.
When water leaks develop from the toilet bowl a certified plumber specializing in toilet bowl leaking repair in Singapore should handle the work. Their team will come equipped with both replacement parts and expertise for both modern and traditional toilet models.
