bleach in toilet to speed things up

[shadowman]

It has been my experience that the chlorine drop-ins for toilet tanks definitely cause premature wear on rubber seals. I have fobidden their use in my house When I worked in a hardware store as a kid, customers would bring in mushy, distorted seals and I would ask them if they used those things. 99% said they did.

Some toilet manufacturers won't honor their warranty if in-tank cleaners are used (not sure how they would know if you did). My guess is that they are claiming that the chlorine damages seals or other parts.

I can attest to the mushy rubber syndrome - my wife is a hardcore puck user, I replace the flapper yearly because it breaks down and turns to mush - usual sign is hearing a small drip drip.
But when it's all said and done, a 1.99 flapper isn't a big deal.
Haven't seen anything else break down over 7 years of usage....

Interesting page and how the cleaning pucks can cause flush problems in some situations.

Having read this thread I had a VERY slow sink. I poured in Draino gel and saw it contained sodium hydroxide and sodium hypochlorite as its active agreements. The stuff opened up 2 slow drains but one was still no better.

So I went out to the pool, got a cup or two of 12.5% from the carboy and poured THAT down the sink, waited a half hour and VOILA! fast-running sink again! That was yesterday.

So it sounds like the summary of these stories is that occasional use of chlorine (or chlorine and lye) to clear a clog is not a problem, but use of the chlorine tablets that expose the seals to more constant levels of chlorine can wear them out or for the blue tabs can change the viscosity to prevent suction flushing.
