Why Act Fast
WHY BROKEN WATER LINES NEED IMMEDIATE PROFESSIONAL REPAIR
At Unclog Drain & Rooter, we respond to water line failures every day across Nairobi – and the damage caused by delays is always significantly more expensive than the repair itself. A broken water supply line wastes thousands of litres per day, drives your water bill to unsustainable levels, saturates foundations, and can contaminate your supply with soil bacteria if left unrepaired.
Stops Water Bill Haemorrhage
A burst or heavily leaking water main can waste 500 to 3,000 litres per day. Unclog Drain & Rooter same-day repair stops this immediately, protecting you from weeks of escalating water charges that compound fast in Nairobi.
Prevents Foundation Damage
Water saturating soil beneath your foundations causes settlement, cracking, and structural movement. Unclog Drain & Rooter acts before a water line failure becomes a structural problem that costs ten times more to resolve.
Protects Water Quality
A cracked supply pipe draws in soil bacteria during pressure fluctuations, contaminating your drinking water. Unclog Drain & Rooter replacement with HDPE or uPVC pipe permanently eliminates contamination risk and corrosion.
Trenchless Where Possible
Unclog Drain & Rooter uses pipe bursting to replace water mains under driveways, gardens, and paved surfaces without excavation along the pipe route – saving your landscaping and reducing reinstatement costs dramatically.
Compliant Documentation
Every Unclog Drain & Rooter water line repair comes with a written completion report, pressure test certificate, and pipe specification document – required for NCWSC reconnection approvals and insurance claims in Nairobi.

How We Fix It
WATER LINE REPAIR METHODS USED BY UNCLOG DRAIN & ROOTER
Unclog Drain & Rooter selects the most appropriate repair method for your specific water line – based on pipe material, depth, location, extent of damage, and surface conditions above the pipe.
Pipe Bursting – Trenchless Replacement
Unclog Drain & Rooter pulls a bursting head through the old pipe, fracturing it outward while simultaneously drawing a new HDPE pipe into place behind it. The full water line is replaced with no excavation along the pipe route – only small entry and exit pits are needed. Ideal for replacing corroded galvanised or old uPVC supply lines under driveways, gardens, and landscaped areas without surface damage.
No Surface Damage
Full Replacement
Point Repair – Targeted Patch
Where Unclog Drain & Rooter leak detection has located an isolated failure – a single crack, burst section, or joint failure – we excavate precisely over that location only, replace the damaged section, and reinstate. This is the most cost-effective approach when the rest of the pipe is in good condition and the fault is confirmed at a specific point by pressure testing and acoustic detection.
Lowest Cost
Fast Fix
Open-Cut Full Replacement
When a water line is extensively corroded, repeatedly failing, too small in diameter for current demand, or made of material no longer fit for purpose (galvanised steel, polybutylene), Unclog Drain & Rooter carries out a complete open-cut replacement with new HDPE or uPVC pipe. We excavate, remove, install, pressure test, and fully reinstate all surfaces. A new meter connection is coordinated with NCWSC where required.
Permanent Fix
50-Year Pipe
Pipe Relining – Internal Repair
For water supply lines in sound structural condition but suffering from corrosion, pitting, or small cracks, Unclog Drain & Rooter applies an epoxy or CIPP liner to the inside of the pipe. The liner seals defects, eliminates corrosion, and restores full pressure integrity without excavation. Suitable for supply lines where the pipe bore is still largely intact and the pipe route makes open-cut work impractical.
No Dig

Recognise the Problem
8 SIGNS YOUR WATER LINE NEEDS REPAIR OR REPLACEMENT
Unclog Drain & Rooter attends hundreds of water line failures across Nairobi each year – and the majority show warning signs weeks before the main event. Recognising these early means a simple repair instead of an emergency replacement.
1
Sudden Drop in Water Pressure
A significant and unexplained drop in water pressure at all taps simultaneously – not just one fixture – indicates a breach or partial collapse in your main supply line upstream of the distribution point.
2
Discoloured or Rusty Water
Brown, orange, or cloudy water at the tap – especially on first draw – indicates internal pipe corrosion or a cracked pipe drawing in soil particles. Galvanised steel pipes over 20 years old are especially prone to this in Nairobi.
3
Unexplained High Water Bills
A sudden or sustained increase in your Nairobi City Water bill with no change in usage is a strong indication of a continuously leaking supply line between your meter and property.
4
Wet Patches or Sinkholes in Garden
Persistently wet ground, patches of unusually green grass, or small sinkholes appearing in your garden above a known pipe route are reliable signs of an underground water main leak saturating the surrounding soil.
5
Water Meter Running When Off
Turn off all taps and water-using appliances and check your meter. If the indicator is still moving, water is escaping somewhere between the meter and your property – confirming an active supply line leak.
6
Visible Pipe Corrosion
Visible rust, green staining, pinhole leaks, or white mineral deposits on accessible pipe sections – at meter boxes, under sinks, or in service ducts – indicate advanced corrosion that will fail completely without intervention.
7
Recurring Pipe Bursts
If your water line bursts or leaks repeatedly after repair, the underlying pipe material is failing throughout. A recurring burst pipe is the clearest signal that full water line replacement – not another patch – is required.
8
Old Galvanised Steel Pipes
Properties in Nairobi with original galvanised steel water supply lines older than 25 years are at very high risk of imminent failure. Unclog Drain & Rooter recommends proactive replacement before an emergency occurs.

Got Questions?
WATER LINE REPAIR AND REPLACEMENT – FREQUENTLY ASKED QUESTIONS
Honest answers to the questions Nairobi property owners ask Unclog Drain & Rooter before booking a water line repair.
How much does water line repair cost in Nairobi?
Unclog Drain & Rooter water line repair starts from KES 12,000 for an isolated point repair of a single fault. Trenchless pipe bursting replacement of a residential lateral (up to 20 m) starts from KES 55,000. Open-cut replacement starts from KES 45,000 for up to 10 m. All pricing is flat-rate and confirmed in writing before work begins – no hidden fees, no call-out charges, and no estimate ranges.
How quickly can Unclog Drain & Rooter respond to a burst pipe?
Unclog Drain & Rooter operates 24 hours a day, 7 days a week including public holidays. Our average emergency dispatch time across Nairobi is 30 minutes. Every vehicle carries the equipment and materials needed for immediate burst pipe isolation and temporary or permanent repair. We do not charge extra call-out fees for emergency or out-of-hours response – the standard evening rate applies between 6 PM and 6 AM.
Can you replace a water line without digging up my driveway?
Yes. Unclog Drain & Rooter uses pipe bursting to replace water lines under driveways, paths, and paved areas without excavation along the pipe route. A bursting head is pulled through the old pipe, fracturing it outward while drawing a new HDPE pipe in behind it. Only small entry and exit pits are needed at each end. This saves your driveway surface completely and significantly reduces restoration costs compared to open-cut methods.
What causes water supply lines to fail in Nairobi?
The most common causes Unclog Drain & Rooter encounters in Nairobi are: internal corrosion of old galvanised steel pipes causing them to scale up and eventually split; tree root intrusion fracturing plastic supply lines near the surface; ground movement from expansive soils in the dry season causing joint displacement; pressure surges from the NCWSC network fatiguing older pipe materials; construction or excavation activity damaging nearby pipes; and simply age-related failure in pipes over 20 to 25 years old.
How long does water line replacement take?
A standard residential point repair takes 2 to 4 hours. Trenchless pipe bursting replacement of a residential water lateral (up to 20 m) is typically completed in one day. Open-cut replacement for a residential property takes 2 to 3 working days including surface reinstatement. Commercial and industrial water main projects are scoped and programmed individually. Unclog Drain & Rooter always provides a clear timeline in the fixed-price quote before work begins.
Do you handle the NCWSC reconnection after replacing a water main?
Yes. Unclog Drain & Rooter provides all the documentation required for Nairobi City Water and Sewerage Company reconnection approvals, including the completion report, pressure test certificate, and pipe specification. We guide you through the NCWSC reconnection process and can liaise directly with their teams on your behalf to minimise delays in restoring your supply.
What warranty does Unclog Drain & Rooter provide on water line repairs?
Unclog Drain & Rooter provides a 10-year written workmanship warranty on all water line repairs and replacements. This covers workmanship defects and the materials we install. Every warranty is backed by a post-repair pressure test certificate. If a warranty issue arises, Unclog Drain & Rooter returns within 48 hours to assess and remedy at no cost. HDPE pipe installed by Unclog Drain & Rooter carries the manufacturer’s 50-year design-life specification.
Do you reinstate the surface after water line excavation?
Yes. Full surface reinstatement is included in every Unclog Drain & Rooter open-cut repair and replacement quote. We backfill and compact all trenches using appropriate bedding material, then reinstate concrete, paving blocks, tarmac, or garden landscaping to match the existing surface as closely as possible. All reinstatement specifications and materials are detailed in your quote before work starts so there are no surprises.
