When it comes to plumbing, often the little things make a big difference. Take, for instance, the water seal in floor and trough drains. Have you ever wondered, "What’s the deal with that?" Well, let me explain why it’s so crucial to maintain a two-inch water seal.

A Barrier Against Odors

Imagine being in a café, enjoying your coffee, and suddenly—bam! There’s an unpleasant smell creeping in. That’s the very problem this water seal is designed to mitigate. If you skimp on that two inches, you could be inviting unwanted sewer gases right into your living space. Now, wouldn't that be a health hazard?
