Why do I need a drain catch?
A drain catch is important if the drain is prone to having items go down it that should not. For example, women with long hair may choose to use a drain catch because long hair that comes out during the washing process will clog a drain very quickly. A drain catch would also be useful in a utility sink where work tools/buckets are cleaned. Sometime screws, stones, larger pieces of debris can get washed down a small sink drain and cause a backup. It is much better to catch this items before the enter your drain system.
