Chlorazone®

Korky Flapper

Posted on

Winter weather brings winter water.  Reservoir water sitting out, like the porch cat’s water bowl.  Gets pert’ cold this time of year.  Freezes over, even.  What does that water do to plumbing system innards?  Not a whole lot, if you’ve got good materials.  One component you do not want failing?  The flapper inside your toilet tank.  The part that opens to let the toilet flush, and closes to let the tank refill.

In 1954 Korky invented the first toilet flapper.  This technology is still used today.  Their current reliability is so good, Korky warrants their premium product at 5 years.  Ten years for their double super premium ‘Ultra’ product line.

Last week my toilet flapper failed to drop over the flush valve.  It ‘stuck open’ and the tank tried to fill it self all night long.  After morning coffee, I didn’t hesitate.  Picking up a new radiator valve for Widow Baxter, I had Mike toss a couple of Korkys into the sack.  Replacement was fast and easy.  The old red Korky had an accumulation of minerals on it but the rubber was still pliable.  Yes, I probably could have cleaned and reinstalled it, but a few bucks for another lustrum or longer of reliability?  No brainer.

The Korky premium toilet tank flapper, made with chlorine resistant rubber.  This basic component of modern life has done as much to promote health, convenience, and conservation as refrigerated food.  Six Thumbs Up to Lavelle Industries of Burlington, Wisconsin!

Chlorazone® rubber is Lavelle’s proprietary family of elastomeric formulations that is specifically designed to withstand chemicals found naturally in water or added to it by municipal treatment facilities. Introduced in 1990, it was the first chlorine-resistant material made available for plumbing applications.  Lavelle
