In the learn something new every day category:
Our home is about 25 years old and the toilets are at least 10 years old (that’s how long we have been in it). Recently two of them developed lazy flushing, where the water sort of swirls around but does not flush completely. It does not back up and overflow just flushes poorly. Since we have a home warranty and I don’t have a closet auger, I called the warranty plumber out. He augured both but that did not help. He declared they were flushing slowly due to a restriction of the internal trap caused by scale build up and they should be replaced. He also said that the warranty company would not cover replacement due to scale build up. (I called them and he was right, they don’t). He said I could try muriatic acid to clean the scale out before forking over for new toilets.
So I did some Googleing and came across www.toiletology.com/lazy.shtml which verified that muriatic acid may help in some cases. But it also has lots of info on lazy flushes caused by “blue goo”. Those are the blue cakes you put in the toilet to make the water clean and pretty blue. www.toiletology.com/blue-goo.shtml My wife had put those in our toilets a few weeks ago. I was skeptical but I cleaned out all the blue goo, ran a clothes hanger thru the rim jets for good measure and presto! Full and complete flushes again! Didn’t even have to do the muriatic acid treatment. Warn your clients when you see the blue toilet water.
edit addition: The more I think about it, the more it makes sense. The problem of the lazy flush was not caused by restricted water leaving the bowl, but by a slowed flow of water entering the bowl thru the small rim jets. Increased viscosity caused by the blue additives slowed the flow enough to prevent the siphoning action from starting. Wish I had thought of that before I spent the home warranty deductible fee. Oh well, at least it wasn’t the full cost of a plumber visit. God bless the internet! Thanks Al Gore for inventing it.:mrgreen:
