Key takeaways
- Most leaks at the base come from the pan connector, the seals between the cistern and the pan, or the flexible hose and tap that feed the cistern.
- When the water appears tells you a lot. Water that keeps coming points to the hose, the tap or the cistern bolts; water only after a flush points to the pan connector or the seal under the cistern.
- Turn off the tap behind the toilet, dry the floor and use another toilet if you have one. Lifting or resealing the pan is licensed plumbing work in NSW.
- Water from the pan connector has been through the bowl, and a slow leak can rot a timber floor or soak under tiles long before you see a puddle.
