While planning a house in Nepal, everyone is concerned about the building, tiles, and interior designs. The plumbing is usually not considered an important aspect, but it can prove to be costly in the long run. Cheap pipes can cause leaks, rust in the water, and maintenance problems. What you are saving on can prove to be an expense you end up paying every year. 

The strength of the plumbing system largely depends upon the quality of the plumbing materials. When it comes to plumbing materials, the climate, water, and soil conditions of Nepal are such that there is greater demand for plumbing materials, and hence, the quality of the materials is of utmost importance. When it comes to residential plumbing, it is always better to use multiple types of plumbing materials. CPVC pipes are better for plumbing within the house, while HDPE pipes are better for plumbing between the water tank and the house, and hence, many people in Nepal prefer Dolphin Polyplast plumbing materials.

Why Pipe Selection Matters More in Nepal

Nepal is a country with geography. From the freezing cold in the mountains to the temperatures in the Terai region Nepal has it all.. This is exactly how the plumbing pipes are affected by the temperatures.

*   Temperature Variation

Nepal has temperatures. The mountainous region is freezing cold while the Terai region is very hot. This affects the plumbing pipes.

*   Earthquake activity

Nepal is located in a zone. During earthquakes the earth. Puts pressure on the underground water pipes. The pipes that are not flexible will crack under pressure.

*   Irregular water supply

Urban areas have storage tanks and pumps for the supply of water. When the pumps start or the tanks are being filled with water pressure is built up in the pipes.

*   Water quality

Minerals, sediment and chlorine can cause weaker materials to deteriorate faster. Metal pipes. Low-grade plastic pipes have a shorter life.

Pipes Commonly Used in Nepali Homes

 PVC Pipes

The commonly used standard PVC pipes can be seen at most construction sites. These are commonly used for drainage systems.

*   Where they work well

*   Wastewater pipes

*   Sewage pipes

*   Rainwater outlets

PVC pipes are easy to handle. Are quite economical. However they are not strong enough for drinking water supply systems. They become brittle in temperatures.

 CPVC Pipes

CPVC stands for chlorinated polyvinyl chloride. CPVC is better than PVC and is used for hot and cold drinking water supply systems.

*   Key advantages

*   Resistant to rust and chemical corrosion

*    internal surface for the free flow of water

*   Resists temperatures up to 90°C

*   Used for drinking water supply systems

These CPVC pipes are most commonly used in homes for kitchen pipes, bathroom pipes, geyser pipes, etc. They can withstand winters in the hill districts of Nepal as well as scorching summers in the plains.

 HDPE Pipes

HDPE stands for high-density polyethylene. It is most suitable for water supply.

These pipes come in the form of a coil. These coils are connected to each other through a heat fusion process. This results in a connection between the coils thus minimizing the chances of leakage.

*   Typical Uses

*   Main Supply Line from Water Source to House

*   Bore Well Connections

*   Underground Tank Systems

The Most Practical Plumbing Setup for Houses

For buildings in Nepal it is recommended that the following plumbing materials be used in combination:

*   For the supply it is recommended to use HDPE pipes.

*   For supply inside houses it is recommended to use CPVC pipes.

*   For drainage it is recommended to use PVC/UPVC pipes.

Why Quality Pipes Matter in Local Conditions

Nepal is divided into three regions: mountain, hill and plain. The plumbing requirements differ for these three regions.

*   Mountain and hill regions

The freezing winter is a problem for this region. Materials that cannot be bent easily tend to break.

*   Terai region

High temperature and humidity will cause corrosion of the metal pipes.

*   Places like Kathmandu and Pokhara

Intermittent supply will cause pressure problems when the tanks are being filled or when the pumps are running.

In these places, quality or cheap pipes will not last long. It is always wise to invest a little more in high-quality pipes, which will definitely be useful for decades to come.

How to Identify Good Plumbing Pipes

It is always necessary to perform checks before you buy the plumbing pipes for your construction work.

*   Look for the brand name, size and pressure rating marked

*   Check for certification from national/international standards organizations

*   Check the surface for color and texture

*   Avoid pipes with cracks, discoloration or uneven thickness

*   Buy pipes and fittings from the same manufacturer

Why Many Builders Choose Dolphin Pipes

There are several construction projects in Nepal that have been using CPVC pipes from Dolphin Polyplast.

The company provides the quality of CPVC pipes that can withstand the environment of Nepal. They consider the pressure strength and temperature of the product. They ensure that the product lasts long.

Practical Tips for a Reliable Plumbing System

A pipe material alone does not guarantee success. Installation practices matter well.

*   Use pipes and fittings from the brand

*   Hire plumbers familiar with CPVC and HDPE installation

*   Avoid excessive joints and sharp bends

*   Protecting the exposed pipes in cold climates with suitable insulation materials

*   Recording the specifications of the pipes for future repairs and renovations

Final Thoughts

A good plumbing system in Nepal can only be achieved through the use of the right materials. The cold winter, summer and changing water pressures are some of the factors that influence the performance of the materials used for the plumbing system.

For the majority of houses CPVC pipes are the best for the water supply system within the house. The HDPE pipes are the best for the water supply system. The combination of the two ensures that the water supply's constant for a long time.

Using the manufacturers of the materials for the plumbing system also ensures that the system is good. Today most builders are using CPVC materials from Dolphin Polyplast for the construction of houses in Nepal. The materials are the best for the plumbing system in Nepali houses because they are efficient and safe for use.

Using the materials, for the plumbing system ensures that the house remains comfortable, efficient and problem-free for a long time.
