My mother in law has an Impulse toilet where the rapide flush push button cup has cracked so needs replaced, but I can't find one anywhere. I found a you tube video showing how to replace it with a different make at https://www.youtube.com/watch?v=X_N1O_azEY4 but when you click the link to buy the replacement it shows a completely different style. Her one has to screw into the section of the syphon.
Can anyone suggest where I can buy one to fit?
