About US

Plumber Dai is a trusted, family-owned plumbing company serving Kathmandu, Lalitpur, and Bhaktapur with pride. With over 25 years of experience, our journey began 27 years ago with Pratap Iron Store, a humble hardware pasal founded by Manab Pratap Karki.

Over the years, Pratap Iron Store grew and evolved into what is now known as MS4 Suppliers, a one-stop shop for everything you need to build a home in Nepal, from cement to rods, pipes to toilet pans, and electrical wires to switches. Even today, MS4 Suppliers continues to serve customers with quality products, and Manab Pratap Karki offers expert consultations to help people build their dream homes, whether on a budget or with luxury finishes.

While running the store, we kept hearing the same thing from our customers: finding a skilled, reliable, and punctual plumber was almost impossible. Some plumbers never showed up, some worked carelessly, and trust was rare.

We decided to change that.

Today, Plumber Dai is known for:

• 24/7 Plumbing Support – Because emergencies don’t wait for business hours.

• Reliable Service – We arrive on time, every time.

• Quality Workmanship – Using the right tools and materials for long-lasting results.

• Local Trust – Serving our community with honesty, transparency, and respect.

From fixing leaky taps to installing new plumbing systems, we provide fast, friendly, and professional solutions you can count on, day or night.
