Piping Services in Karachi:
New Lines & Re-Piping
Low water pressure on the top floor. Rusty water from the tap. A new bathroom with no proper supply line. A shop that needs a fresh pipeline before it opens.

When Do You Need
Piping Services?
Most customers call us for one of these situations. Whether building new or fixing old, proper piping at the start protects your investment for many years.
New Builds & Renovations: New houses, shops, extra floors, or moving a kitchen/bathroom basin needs new pipe routes planned properly before closing walls.
Old Pipes Failing: Rust-coloured water, low pressure and repeated leaks are signs. Re-piping is cleaner than patching leaks every week.
Better Pressure & New Equipment: A blocked or narrow pipe limits flow. Also, installing a new geyser, motor or tank requires strong connections that handle heat and pressure.
Piping Services for
Homes, Shops & Factories
The basic principles are the same everywhere. But each type of property has its own priorities. For Houses and Apartments: Families care about pressure, clean water and a neat finish. We plan lines for each bathroom, add valves for easy maintenance, and keep noise low. In apartments, we follow building rules to avoid disturbing neighbours.
For Shops, Offices & Clinics: Business owners need speed. We plan work around your timing. For offices, we plan washroom and pantry lines. For clinics, we plan clean layouts without dead ends. For Restaurants & Factories: Kitchens use a lot of water and produce greasy waste; we install strong lines and proper traps. Larger properties need long pipelines and zone valves so you can maintain one section without stopping the whole facility.
Choosing the Right Pipe & Cost Factors
The pipe material affects the price, the life of the system and the way it is installed. We choose the pipe according to the use, not what happens to be in stock. The cost depends on the scope of work, pipe material, length, concealed vs surface work, and finishing required. We quote clearly before starting.
PPR & CPVC for Supply
PPR uses heat fusion for strong joints and handles hot/cold water without rusting. CPVC uses solvent cement and has good heat resistance. These are our top choices for concealed supply lines inside walls.
uPVC & HDPE
uPVC is light, affordable, and perfect for cold water, drainage, and waste lines (not hot water). HDPE is flexible and corrosion-resistant, making it ideal for underground and outdoor main lines.
GI & Brass Fittings
Galvanised Iron (GI) rusts over time and is mostly replaced in modern work, but brass fittings and valves provide strong, long-lasting connections to taps, motors, and equipment where threads are needed.
Concealed or Exposed Piping:
Which Should You Choose?
Both options have their place. Concealed Piping: The pipes run inside the wall or floor, and only the taps and fittings are visible. It gives a clean finish, common in new construction. The downside is that repairs may need wall opening, which makes testing before closing very important.
Exposed or Surface Piping: The pipes run on the wall, along the ceiling or in a shaft. It is faster to install, easier to inspect and cheaper to repair. It works well in workshops, rooftops, rented properties and older buildings. With clean routing and painted pipes, it can also look tidy.
Our Advice: If you are building or fully renovating, concealed piping with proper access points is usually better long-term. In rented homes or commercial units where layouts change, surface piping keeps things flexible.
Our Piping Services in Karachi
We handle a wide range of piping work. You can book one service or combine several in the same visit.
New Water Supply Piping
We design and install complete supply lines for new houses, apartments, and shops. The plan covers tank connections, branch lines, and isolation valves.
Hot and Cold Water Lines
Hot and cold lines must be kept apart. We install both, add insulation where needed, and connect them to geysers, mixers and showers.
Re-Piping & Replacement
For old buildings with corroded pipes, we replace the lines in stages or all at once. We plan room by room so you do not have to shift out.
Bathroom & Kitchen Piping
We fit and shift supply and waste lines for basins, toilets, sinks, and dishwashers, aligning properly with your tiles and fittings.
Drainage & Sewerage Piping
We install waste pipes, soil pipes and sewer connections with a steady slope and proper bends so waste flows freely and does not choke.
Water Tank & Motor Piping
Tanks and boosters need correct suction lines, non-return valves, and overflows. We arrange these for smooth running and easy maintenance.
Outdoor & Underground
Garden, boundary and underground lines need strong protection from soil and sun. We use suitable pipes laid at a safe depth.
Commercial & Industrial Piping
Restaurants, clinics, and factories need complex lines. We plan routes for high-volume use and heavy equipment, coordinating with your contractors.
Pipe Shifting & Extension
If you are moving a basin, a kitchen sink or a washing machine point, we extend or shift the pipe with minimum damage to the wall and floor.
Pipe Testing & Inspection
We test pipelines under pressure for weak joints. If you suspect a hidden leak, our water leak detection service finds it without random breaking.
How We Do Piping Services Step by Step
A clean process gives a system that works for years. This is how our plumbers handle a typical job.
Our Installation Process
Site Visit & Requirement Check
We check the plan, note the bathrooms, appliances, floors and any special needs like rooftop/underground tanks.
Layout & Material Plan
We plan routes to keep lines short, avoid unnecessary bends, and keep them away from electrical wiring. You receive a clear estimate.
Marking & Preparation
We mark pipe routes on the wall. Where wall cutting is needed, we cut neat channels and protect surfaces to limit dust.
Installing & Joining Pipes
Pipes are installed correctly (heat fused for PPR, solvent cement for CPVC/uPVC). Supported with clamps so they don't sag.
Fitting Valves & Testing
We fit isolation valves on each branch. Before closing walls, we test lines at high pressure. If the gauge drops, we fix it.
Closing, Flushing & Handover
We close channels with cement, flush lines to remove debris, and show you the layout and shut-off valves.

How to Look After Your Pipes & Common Piping Problems
How to Look After Your Pipes
Good piping lasts many years. A few habits keep it in good condition. Know where your main valve and the branch valves are, and check that they turn. Flush the lines after long periods of no use. Clean your water tank regularly, because tank sludge can enter the lines. Our water tank cleaning service helps.
- Do not pour grease, oil or heavy waste into drains. See our drain cleaning page if your drains are slow.
- Cover or insulate exposed roof pipes.
- Watch for damp patches, rust marks and low pressure, and act early.
- Do not hang heavy items from pipes.
- Get the system checked once a year, especially in older buildings.
Piping Problems We See Often in Karachi
Karachi's climate, water quality and building habits cause issues we see again and again. Corroded GI Pipes: Old houses have GI pipes that rust inside, causing brown water and low pressure. Low Pressure on Upper Floors: Narrow pipes, scale, or a weak motor limit flow. Poor Joints: Joining different pipe types without adapters, badly fused PPR, or weak glue joints cause leaks. Wrong Drain Slope: A flat drain collects waste and chokes. Heat Damage: Roof pipes get brittle under the sun if not UV-resistant or covered. Salt & Moisture: Metal fittings corrode faster in coastal areas; brass and good plastic last longer. Poor Additions: Extra bathrooms tapped into the nearest pipe overload the system over time.

Frequently Asked Questions
The common questions property owners in Karachi ask most often.
What are piping services?
Piping services cover the planning, installation, replacement, extension and testing of water supply, hot water and drainage pipelines in a building. They include work on tanks, motors, geysers and outdoor lines.
Which pipe is best for home plumbing?
PPR is a popular choice for concealed hot and cold water supply because it has strong fused joints and does not rust. uPVC is common for drainage, and HDPE suits underground lines. The best choice depends on the use.
How much do piping services cost in Karachi?
The cost depends on the scope, pipe material and size, length of the lines, concealed or surface work, fittings and finishing. We inspect first and give a clear estimate before starting.
How long does a re-piping job take?
A single bathroom can take one to two days. A full house may take several days, depending on the layout, the wall type and the finishing work. We can plan the work in stages, so you do not have to shift out.
Can you replace old GI pipes without breaking the whole house?
Often, yes. We plan the route, replace the lines section by section and open only the areas that need it. Sometimes we run the new line on the surface or through a shaft to avoid heavy wall cutting.
Do you install hot water lines?
Yes. We install heat-safe pipes for geysers and heaters, and we insulate the lines where needed. We also make sure that hot and cold pipes are properly separated.
Why is my water pressure low even with a new motor?
The pipe may be too narrow, corroded, partly blocked or full of bends. A leak or a wrong valve setting can also reduce pressure. We check the whole path from the tank to the tap to find the cause.
Do you test the pipes before closing the wall?
Yes. We pressure test every new line before closing any wall or floor. It confirms that the joints are sound and prevents expensive repairs later.
Can you extend or shift a bathroom or kitchen line?
Yes. We extend or shift the supply and drain lines with minimum damage to the surroundings, and we test them before finishing the wall.
Do you handle commercial and factory piping?
Yes. We handle piping for shops, offices, restaurants, clinics and factories. We plan the system for higher use and add zone valves for easy maintenance.
How fast can your team reach me?
We have teams in different areas of Karachi, and they can normally reach you within 30 minutes. Traffic and weather may affect the timing.
