Chemical drain cleaners are not great for your pipes, especially when dealing with older plumbing or if you’re not sure what material your pipes are made of. Rather than pouring potentially damaging chemicals down your drain, stock up on some good old-fashioned white vinegar. Vinegar can be used to break up mineral deposits caused by hard water which can lead to clogs and it can be used clear aerator on faucets or shower nozzles thereby improving water pressure.
