Before we start: what we know about Baqiq

Team note on Baqiq: Kashf teams serve this city and its nearby districts with the same documented inspection standard: device-based leak detection without demolition, a written report, and a clear scope before any work begins.. The centre of Baqiq sits about 83 m above sea level (SRTM open elevation data).

Picture a family that owns a duplex in Baqiq, with two households sharing one building and one aging water network. Over the years, a leak behind a wall, slow drains, or weak water pressure on the upper floor starts to disrupt daily life for both units. The owner wants the pipes fixed properly, but does not want the work to drag on or leave the property in worse shape than it was found. For a building of this type, the plumbing is often hidden inside walls and ceilings, so a small problem can turn into a larger job before anyone notices.

Baqiq sits about 83 m above sea level, which matters more than it might seem for water supply. Elevation affects how pressure reaches upper floors, so a duplex that looks fine at ground level may show weak flow on the second level. Owners here should check pressure at the highest outlet first, before assuming the fault lies in the fixtures. Because the terrain is not flat, any repiping plan should consider where the main supply enters the building and how the lines rise to each unit, rather than copying a layout from a flatter site.

A practical sequence keeps the job under control. Start with a site visit and quantity survey, which typically costs SAR 150–400 per visit, so you know the scope before committing to materials. Next, mark which lines are old, leaking, or undersized, and decide whether the two units can be worked on in stages. Plan the wall and ceiling openings together with the finishing trades, since plastering, painting and any gypsum board false ceiling must follow the pipe work. Where walls are reopened, plaster with guides and paint after surface preparation, and tile only after the plumbing is tested. Keep the work for each unit in a fixed order, and confirm pressure and drainage on both floors before closing the walls. Doing it this way limits disruption and avoids reopening finished surfaces later.

In a duplex, the two floors often share lines, so tests are done floor by floor.
