What clogged my drain and what can I do about it?
More like what doesn’t clog your drain, am I right? Beauty products, hair, dirt, grease
and food waste are all day-to-day culprits that can lead to blocked drains. At home you
can help avoid build up by installing a drain catcher to catch physical debris. After that,
a great way to address small clogs is by pouring a mixture of hot water, baking soda,
and vinegar down your drains to loosen the build-up. If that doesn’t work, it’s time to call
Magnum Plumbing!

leaking. There could be valve corrosion, problems with the washer, worn out seals, or
general (and unfortunate) broken pipes or fittings. While this list of potential problems

Is there really a difference between hard and soft water?
Yes. Hard water, in short, is water that contains an excessive quantity of dissolved minerals like calcium, magnesium, and so on. Soft water, on the other hand, is treated so harmful minerals don’t build up. For comparison, natural rainwater is soft, not hard. Hard water can cause considerable damage to plumbing fixtures, pipes, and the things water in your home touches such as laundry and even your skin. If you suspect you have a hard water problem, we recommend getting in touch with a Magnum Plumbing professional to get it fixed before it causes any expensive, long-lasting damage to your plumbing.
