Troubleshooting Tips:

I need to hold down the handle to get a complete flush or my toilet flapper is closing too quickly. We need to adjust the flapper to stay open a bit longer. We recommend turning the red band to the higher numbers located on the underside of the flapper (closing off the holes and allowing the flapper to float longer). This will prevent you from having to hold down your toilet handle.


My toilet flapper is staying open too long or my toilet is double flushing. We need to adjust your toilet flapper to flush less water. This is accomplished by turning the dial on the flapper to open up larger holes - this will allow the flapper to closer quicker and avoid double flushes. There are several settings to get the perfect flush.


How to attach the flapper chain correctly: Attach the flapper chain with minimal slack and to the hole on the flush lever arm, most directly above the flapper (this helps to ensure the flapper is being lifted straight up and down and not side to side). If there is too much slack in the chain, this can cause a weak flush. If there is too much slack, this can create a slow leak beneath the flapper.
