Repair and Replace a Sink Strainer

 
Repair and Replace a Sink Strainer Your sink strainer isn't something you pay much attention to in everyday life, but as soon as there's a problem, suddenly it's got your attention. To repair or replace a sink strainer, you'll need to take it apart from the rest of the sink. Once disassembled, clean the strainer basket and inspect the parts. If you have a chrome drainpipe, you may want to replace it with plastic, as chrome tends to corrode. Other than that, you're not likely to have to replace anything more than the washers and gaskets if you don't mind using old parts
