In this post, we’ll take the plunge and break down everything you need to know about World Plumbing Day. We’ll review when it takes place and how plumbers can use it to promote their brands. Let’s dive in. 

What is World Plumbing Day?

World Plumbing Day is an annual event that recognizes the role plumbing plays in public health and sanitation. The World Plumbing Council established it to highlight how proper plumbing systems contribute to clean water access, disease prevention, and overall quality of life.

Think about it — without plumbing, there’d be no safe drinking water, no efficient waste disposal, and no hot showers after a long day. While plumbing often goes unnoticed when things are working well, this day reminds people how essential plumbers are to modern life. And, trust me, nothing is more valuable than an emergency plumber when a rush of water floods your floors.

For plumbers, World Plumbing Day isn’t just about awareness — it’s a marketing goldmine. It’s an opportunity to promote your services, build customer trust, and show that you’re more than just a business; you’re a vital part of the community.

When is World Plumbing Day?

World Plumbing Day is celebrated on March 11. In 2025, it will fall on a Tuesday, making it an excellent mid-week event to engage customers and offer special promotions.

This year’s theme? “Plumbing is More.” World Plumbing Day will focus on the role plumbers play in building better communities.

How to Celebrate World Plumbing Day

Now that you know what World Plumbing Day is, let’s talk about how to use it to market your business. Here are some practical and creative ideas.

1. Offer a limited-time World Plumbing Day discount.

People love a good deal. Customers always like to save a few bucks, whether it’s a discount or a giveaway. Offering deals is a great way to distinguish yourself from competitors and can lead to repeat purchases. If you’re constantly offering deals, people will follow your brand so they can take advantage of them. 

For World Plumbing Day, consider offering limited-time discounts on common services such as:

• Plumbing inspections
• 10-15% off repairs
• Discounted drain cleaning services

Promote these deals before March 11 through email, social media, and your website. I like how this example provides context about World Plumbing Day and directs people to its deal via the carousel. I recommend highlighting your offer in the social media caption to make this promotion more effective. 

2. Run a social media campaign.

Social media is a powerful (and free) tool for reaching potential customers. A good social media campaign increases brand awareness and re-engages previous buyers. You can use social media to share updates from your company, launch new deals, or publish compelling content that gets people interested in your business. 

Here’s how you can use social media for World Plumbing Day: 

• Use a hashtag like #WorldPlumbingDay2025 and encourage customers to share their plumbing stories or photos of upgraded bathrooms.
• Post behind-the-scenes content of your team at work, showcasing their expertise.
• Share fun facts about plumbing (use the ones above) to educate your audience.

3. Host a giveaway.

Giveaways are an excellent way to boost engagement and attract new customers. But, what can you give away if you don’t sell any products? 

Plumbers can offer complimentary services and discounts on World Plumbing Day. Some ideas include:

• A free plumbing inspection for one lucky winner
• A gift card to a home improvement store
• A “plumber’s survival kit” with tools and supplies

You can also find prizes you know customers will want, like tickets to a game or show. For example, one brand created a poster contest for kids on World Plumbing Day. The winner received an iPad and $500 for his college fund. 

If you’re hosting a giveaway, I recommend using social media to promote it. Require participants to follow your page, like your post, and tag friends to enter — this will spread awareness and encourage people to sign up.

4. Partner with local schools or community organizations.

World Plumbing Day is a great chance to give back to your community and improve your brand’s reputation. By partnering with local schools and community organizations, you’ll forge a stronger connection with your customers, which will lead to word-of-mouth marketing opportunities. 

Consider:

• Visiting local schools to teach kids about water conservation and plumbing careers
• Donating plumbing services to a local shelter or nonprofit
• Sponsoring a community event related to home improvement or sustainability

For example, here’s a company that donated to the Mechanical Contractors Association of Canada. This gesture was covered by a local news station, generating more publicity for the brand. 

These efforts show your business cares about more than just profits, which can build trust and increase customer loyalty.

5. Write a blog post or record a video.

Blogs are great for your website because they improve SEO, or search engine optimization. By writing about plumbing, Google views you as a trusted expert and directs people to your website by ranking you first on its results page. 

Tip: That was a really simplified explanation of SEO. If you’re looking for more details, I recommend reading this guide from our SEO expert. 

Writing a blog post about World Plumbing Day can boost your brand’s visibility and generate more traffic to your site. Here are some topics you could cover: 

• The importance of plumbing in everyday life
• Common plumbing problems and how to prevent them
• The history of plumbing and its innovations

Don’t forget to use keyword research to target phrases and words your customers are searching for. 

Not a fan of writing? Create a short video instead. A “Did You Know?” video featuring plumbing facts or a quick DIY tip can generate interest and shares. Post these videos on your website, YouTube, and social media channels. 

6. Create an email marketing campaign.

Email is great for marketing because it speaks directly to customers. Your email subscribers have already demonstrated interest in your brand, so email is a great place to engage them and share your latest products, services, and deals. 

Reach out to your existing customers on March 11 with an email newsletter highlighting:

• The significance of World Plumbing Day
• A limited-time discount or promotion
• Tips for maintaining your plumbing system

Ensure the email is friendly and engaging — no one likes boring sales pitches. It should also be mobile-friendly so it can be viewed on the go. 

Tip: Email marketing software can automate this and personalize your message for each customer. 

7. Get featured in local news.

News stations won’t promote your business but will cover interesting stories like events, donations, and special promotions.

If you want to get your business on the news, contact local newspapers, radio stations, or community blogs to tell them how you celebrate World Plumbing Day. If you’re hosting an event, offering a special promotion, or doing community work, they might be interested in featuring your business.

By using social media, offering discounts, and sharing educational content, you can turn World Plumbing Day into an effective marketing campaign that benefits your business long after it’s over.
