Water Supply Line Installation

Construction Sewa designs and installs water supply lines for homes, apartments, hotels, and commercial buildings across Nepal. We size every pipe to your fixture count, route it so you're not losing pressure halfway through the building, and pressure-test the whole system before handover using PPR, CPVC, uPVC, or HDPE, whichever actually fits what you're building.

3.      Requirement Assessment: we calculate fixture count, water demand, and pressure requirements

4.      Layout Planning: mapping out main lines and branch connections

5.      Pipe Material Selection: recommending PPR, CPVC, uPVC, or HDPE based on your needs

6.      Pipe Installation: pipes cut, fitted, and secured according to the layout

7.      Jointing & Connections: heat-fused or solvent-welded joints for leak-proof connections

8.      Pressure Testing & Leak Inspection: the system is tested and every joint checked under pressure

9.      System Flushing: lines flushed to clear debris before water reaches your taps

10.   Final Inspection & Handover: a complete walkthrough before the system is handed over

Materials & Options

•       PPR: heat-fused joints, handles hot and cold water well; a strong all-around choice for homes and apartments

•       CPVC: rigid and heat-resistant, well-suited to hot water systems and commercial buildings

•       HDPE: flexible and durable; the standard choice for outdoor, underground, and long-distance runs

•       uPVC: affordable and corrosion-resistant, best suited to cold water lines and outdoor runs

We'll help you weigh these against your budget, hot water needs, and building type when we get to the material selection stage of the process.

Every property's laid out a bit differently, every job's its own case a site visit is really the only way to land on a quotation that's actually accurate.

Frequently Asked Questions

Which pipe is best for home water supply?

For most homes, PPR is the safer bet it handles hot and cold water without issue and holds up well over the years. CPVC's a solid alternative too, especially if hot water lines are the priority.

What is the difference between PPR and CPVC pipes?

Both deal with hot and cold water fine. The real difference is in the joints PPR gets heat-fused, CPVC uses solvent welding. PPR's a touch more flexible; CPVC's more rigid and can take slightly higher temperatures.

Can old water pipes be replaced?

Yes. We handle full pipe replacement for old, corroded, or leaking systems including occupied buildings, where we plan the work around your daily routine instead of disrupting everything at once.

What causes low water pressure?

Usually it's undersized pipes, a poor original layout, corrosion narrowing the pipe from the inside, or a water source that isn't positioned to gravity-feed properly. A site inspection generally pins down the exact cause, and where a boost is needed, our Water Motor Installation service can add a booster pump.

How long does water supply line installation take?

Depends on the property size and whether it's new construction or a renovation. A standard home job usually takes a few days; bigger commercial projects run longer. We'll give you a real timeline once we've seen the site.
