Why Toilet Installations Can Get Complicated

Installing a toilet may sound simple, until you encounter hidden issues such as:

  • Corroded or unevenly set floor flanges
  • Off-level subfloors that cause rocking
  • Incorrect rough-in distance
  • Faulty wax rings or loose seals causing leaks or sewer odours
  • Poorly aligned water supply lines or bolts
  • And more.

Flow-State prevents these headaches with code-accurate installation and tested leak prevention, every time.
