Tell us about your project
Call or message us on WhatsApp and tell us the building type, its stage and the rooms to be first-fixed, so we understand what the pipework needs.
- 2
Setting routes and falls
Supply and drain routes are drawn and drain falls are set before any cutting, because the slope of a drain pipe directly affects how well it clears later.
- 3
Laying and securing
Pipes are laid in walls and floors and secured with clips, and joints are made carefully, because a weak joint behind the wall may not show for years.
- 4
Pressure test before closing
Before plastering or casting the floor, the supply line is tested under pressure to confirm the joints are sound. This is the only time a fault can be fixed without demolition.
Correct first-fix prevents demolition later
- We lay the pipes before burial on set routes
- We set the drain falls accurately at this stage
- We run a pressure test before closing the wall or floor
- We take your request by phone call or WhatsApp message

The service in Al Ahsa
In a home in a city like Al Ahsa, pipes and drains need precise routes from the kitchen and bathroom to outside the house or to a septic tank. Drains must slope at the right angle so water flows, or it pools and dampness builds up. Groundwater in Al Ahsa often contains salts, so pipes need to be placed away from moisture and pooling. Every route and joint is checked before building begins, because rework after that is very costly.
Al Ahsa is a city in Al-Ahsa governorate in the Eastern Province, close to As Saifa District, Ayn Najm District and Al Muhammadiyah District.
Most plumbing first-fix errors occur at bathroom and kitchen corners, where several pipes meet in a tight space.

Questions about Plumbing first-fix in Al Ahsa
First-fix is when pipes are laid inside walls and floors before plastering and tiling, in a new building or a major renovation. Ordinary plumbing work deals with the visible fittings, taps and sanitary ware after finishing. Each stage has its own requirements and tools.
Because the pressure test reveals any weak joint or fault in the line before the wall is closed. After plastering and tiling, the pipe cannot be reached without demolition. This stage is the only chance to fix a fault without extra cost.
It is very difficult after casting and often requires breaking part of the floor. This is why drain outlet positions are set accurately before casting, based on the planned sanitary ware positions in each room.
The fall matters greatly. Too little and water sits in the pipe, leaving solids that build up into a blockage over time. Too steep and the water runs ahead of solids, which are left behind. Horizontal drain pipes have an accepted fall range that should be followed.
Tell us the building type, the number of floors and the rooms to be first-fixed, and whether it is a new build or a partial renovation. If you have a layout of the planned sanitary ware or the drain outlet positions, mentioning it helps us understand the scope of work. Call or message us on WhatsApp.
Each drain's slope is checked with a level, pipes are tested under water pressure to ensure no leaks, and every joint and connection from kitchen and bathroom to outside is inspected.
Call Al Raya after excavation and foundations are done but before walls and building start, when the site is open and routes are accessible. Describe the location of the kitchen, bathrooms and the external tank or drain.
