Thank you for your comments. Unfortunately, the model we provided is for Eljer toilets and is NOT designed to be shortened or cut as this will affect the Pitch and Throw of the Arm - thus changing the Flushing pattern.... and the resulting problems that you had.... In future, should you ever have any issues with HAG Products, the team is here for customers on line always and we'd have advised how to resolve this. Regardless, we are happy that you found a solution that works for you. Happy Flushing
