Negative Positive
Title: horrible
Review: I am a contractor, and not stupid - couldn't make it work. I am sure I understood how to connect the "extra" chain for the leak-preventing valve (I carefully, carefully reviewed and reviewed again the instructions which intially are somewhat daunting since they insist on using non-laymen terms to describe objects). But valve would not function properly (would not fill). So I tied the chain up so that the valve is deactivated. Toilet worked fine for 2 days, then, stopped filling back up. So i let chain loose, thinking that would deactivate valve. Nothing I could do would get it to consistantly fill up the toilet. Nice idea but putting in practice seems to be overly complicated.
Is the review positive or negative?
