Every drain is supposed to have a low bend called a trap – sometimes called a P-trap. As water drains, it collects in the trap and blocks sewer gases and other unpleasant odours from coming into your home. If your drain smells bad, it could be that there’s something wrong with the trap, or it was never installed in the first place. Either way, Kitchener Plumbing Pros can help – contact us today for drain repair services.
