When the seal inside the toilet basin incompletely seals, and water slowly drains out, do you need to replace the entire internal mechanism?
One of our toilets has “sprung a leak” inside the basin, and after flushing, the bottom seal doesn’t close well, leading to a slow leak and subsequent refilling of the basin. This continues indefinitely. What is the simplest way to fix this? Does the entire apparatus need to be replaced, or simply the bottom seal (somehow)?
