About this service
Few homes come with accurate plumbing drawings, and even when they do, the pipes rarely follow the plan exactly. Owners of older village houses, apartments renovated several times over, or villas with long garden runs to septic tanks and soakaways often have no idea where their pipes actually go. That becomes a problem the moment someone picks up a drill, a breaker or an excavator.
Pipeline mapping solves it. Using detection equipment, professionals trace supply and drainage pipes through walls, floors and the ground, mark their routes and, where requested, record them in a simple sketch or photos. You can then plan renovations, landscaping or repairs around facts instead of guesses.
What pipeline mapping can include
- Supply pipe tracing: following hot and cold lines in walls and under floors before kitchen or bathroom work.
- Drain route tracing: locating waste pipes, manholes and the route to the sewer, septic tank or soakaway.
- Sonde tracing: sending a small transmitter through a drain and following its signal above ground to find position and depth.
- Heating and garden lines: identifying underfloor heating loops, irrigation lines and supply pipes to outbuildings or pools.
- Marking and records: marking routes on site and providing sketches or photos you keep for the future.
When mapping is worth doing
Before renovations. Moving a kitchen, removing a wall or laying new flooring is much safer when you know which pipes are underneath.
Before landscaping or building. Paving a driveway, digging a pool, planting trees or putting up an extension over an unmapped drain can lead to expensive damage or lost access later.
When tracking down leaks. Knowing the route narrows the search area for a hidden leak and limits how much needs to be opened up.
When buying or managing property. Landlords and holiday-home owners benefit from a record of where services run, useful for any trade that works on the property later.
How the work is carried out
The method depends on the pipe material and what it carries. Metal pipes can often be traced with electromagnetic locators. Plastic pipes are harder to detect directly, so professionals may insert a sonde or traceable rod, or use acoustic methods on pressurised supply lines. Drains are usually traced from manholes and access points. Ask in the offer which equipment will be used for your pipes and whether depth readings are included.
Mapping water and drain pipes does not cover electrical cables or gas lines. If you plan to dig near those, contact the relevant utility and use a suitably qualified professional.
What affects the cost
The area to be mapped, pipe materials, the number of access points, the equipment required, ground conditions and whether a written sketch or record is wanted all influence pricing. Sharing any existing plans and photos when you post your job helps professionals quote accurately.

Why choose this service
Avoid Costly Strikes
Drilling into a pressurised pipe or breaking a drain while digging can flood rooms or halt a project. Mapping first prevents those expensive surprises.

Village houses and renovated apartments rarely match their drawings. Tracing shows where pipes really run after decades of alterations and repairs.
Records for Later
A marked sketch or photo record helps every future plumber, builder or landscaper who works on your property, saving time on each job.
