Visit from the pro: @mmplumber

Solving problems connects people. This is precisely one of the reasons why Matthew Marciniak, aka @mmplumber, became a plumber 18 years ago. To this day, he loves tackling challenges, finding solutions, and genuinely helping people with his work. And that's exactly what he shows on social media – with incredible success. He is the most successful HVAC-R content creator worldwide, with almost 1 million followers on Instagram and almost 800,000 followers on YouTube...

We at DERBLAUE® have also made it our mission to identify challenges in everyday craftwork and to create simple, clean, and well-thought-out solutions for them.

What connects us with Matthew is far more than just a love for craftsmanship. It's the same attitude, the same standards, the same values. And over time, a genuine friendship developed from that.

In our Family Podcast, we talk with him about our shared journey, about craftsmanship, about real community, and about why the best connections often arise where people share the same passion. Look forward to a conversation about friendship, solidarity, and the joy of creating solutions every day.
