In tank bown cleaners

[Kevink1955]

I know that many do not like in tank cleaners as they damage most flapper valves in less than 2 years, that being said and assuming I will replace the flapper when needed I have a question.

Has anyone ever had any problem with the cleaners decomposing or making the plastic fill valve or it's parts brittle. I had someone tell me that they had a fill valve crack off just inside the tank resulting in full flow of water that the overflow could not handle resulting in a flood.

At work I have seen that some chemicals cause plastics to decompose or become brittle, am I overthinking this?

I do not want to flood the house for the sake of a clean bowl

I think you know the answer to this and are just hoping someone will OK using some chemical in the tank. That just ain't gonna happen! How "clean" do you think the bowl has to be? If you feel that just looking clean isn't satisfactory, then use a liquid bowl cleaner and brush occasionally, but keep the chemicals out of the tank.

There are a couple of products that add bowl cleaning chemicals to the water that goes down the overflow to refill the bowl. One of those might solve your problem without the damage to tank parts.
