Plumbing Work Practices / Leaking Basket Strainers - Plumbers Putty - Silicone Caulk?
« on: April 04, 2011, 10:08:58 PM »
Over the course of time in our plumbing profession we have set 1000's of fixtures that require a waterproof type connection where the drain assembly connects to the fixture. For decades, the most common/sensible product used was plumbers putty. Plumbers putty is a pliable product, very similar to play-doh that is a kids favorite in their childhood growing up. With putty though, it's a product that works as a filler between the flange of a drain opening or basket strainer. Putty is also used for the installation of garbage disposal flanges as well.
But as time progresses forward, it has been more than obvious that plumbers putty has a limited life, and can lead to leaking under these flanges/strainer baskets as water can loosen/break down the once dry connection. With certain types of sinks, like Kohler kitchen sinks that are either cast iron or americast (spun polymer with hardened finish similar to porcelain) the angle of the opening where the strainers go can be quite large.
