Water Line Installation
Whether you're building a new home, adding an extension, or upgrading an outdated supply system, professional water line installation ensures your property has a reliable, code-compliant water supply from the start. In Nairobi's growing residential areas — Syokimau, Ruiru, and Kitengela among them — new water line installation is one of the most requested plumbing services as homeowners connect to county water mains or set up borehole and tank-fed systems.
What Does Water Line Installation Involve?
Water line installation covers the planning, laying, and connection of pipes that bring water from a source — whether the Nairobi City Water and Sewerage Company (NCWSC) mains, a borehole, or a storage tank — into a property's plumbing system. This includes main supply lines, branch lines to individual fixtures, and connections to water heaters and outdoor taps.
When You Need Water Line Installation
Common situations that call for water line installation include:
- New construction requiring a full plumbing supply network
- Home extensions or additional bathrooms/kitchens
- Switching from an unreliable water source to a borehole or tank system
- Replacing an undersized main line that can't support current household demand
- Relocating water lines during a renovation
The Water Line Installation Process
Our approach to water line installation follows these steps:
- Site assessment and planning — mapping fixture locations, water source, and required pipe sizing.
- Material selection — PPR, PEX, or copper chosen based on application and budget.
- Trenching or wall chasing — pipe routes are excavated or channeled as needed.
- Pipe laying and connection — supply lines are installed, joined, and secured according to plumbing best practice.
- Pressure testing — the full system is tested for leaks before backfilling or wall closure.
- Final connection and commissioning — fixtures, tanks, and heaters are connected and the system is flushed and activated.
