I got this from Menard's about 6 years ago. It's the one that was able to flush a bucket of gulf balls. It has been an excellent unit and has never let me down (excepting once when I didn't fully commit to the flush).
It started slowly seeping so I replaced the seal with great hopes. It might have gotten better, but it still seeps. I can't see why I would have to replace the whole "tower". I added some web images below.
I'm thinking of putting a 3/4" stainless nut to add some weight to the "float".
Has anyone else had this problem with this unit and been able to fix it ? Thanks in advance.
