What is a kitchen sink flange?
The flange in a kitchen sink is designed to create a watertight seal between the sink and the plumbing beneath it. The seal gets exposed to dramatic fluctuations in water temperature, and over time it will eventually break down. Fortunately, repairing a leaky kitchen sink flange can be accomplished in one afternoon.
How do you remove an old sink flange?
Turn the locknut counterclockwise to remove it and release the flange from the sink. Tap the bottom of the sink drain flange from beneath the sink with the side of the pliers if the flange is stuck to the edge of the sink opening. This should loosen the grip on the flange and allow you to lift it from the sink.
Can you replace a sink flange?
You can replace just the flange when making the repair, or the whole bathroom faucet. Whichever option you choose, you need to disconnect the plumbing below the sink so the flange can be unscrewed.
Is it better to use plumbers putty or silicone?
Both plumber’s putty and silicone are sealing compounds designed to provide a water tight fit for pop up drains, sink strainers, undersides of fittings, showers and drains. Plumber’s putty is more traditional while silicone caulking is a more modern product, but either one (in most cases) can get the job done.
Can I use plumbers putty instead of silicone?
Plumbers use it because it remains soft for a long time and maintains a watertight seal, but unlike silicone and other types of caulk, plumber’s putty is not an adhesive, so a fixture or drain part sealed with putty remains easy to remove if you ever need to replace it.
Is duct seal the same as plumbers putty?
duct seal (mostly used for sealing electric panels and such from water infiltration) is very similar to plumber’s putty but never dries out.
