Hot and cold supply
PPR runs sized for sink, dishwasher and fridge-water connections

Farwaniya
Kitchen plumbing in Rai Industrial addresses mixed commercial and residential buildings with high-pressure supply systems. We install large-diameter supply, waste and vent lines rated for heavy loads before concrete walls seal.
Rai Industrial has modern buildings with large kitchens in offices or small hotels, and supply systems are centralized and high-pressure to serve multiple floors. We choose waste pipes at least one hundred fifty millimetres in diameter to handle flow from multiple taps open together. Waste must reach a treatment tank underground because the public sewer near The Avenues Mall cannot take high volumes.
Rai Industrial is located in Farwaniya governorate, a planned industrial and commercial zone where infrastructure is robust and spaces are generous.
Total flow from all taps running simultaneously is measured before handover to confirm pressure stays above the minimum threshold.
PPR runs sized for sink, dishwasher and fridge-water connections
uPVC drain at correct fall to stop grease settling inside the pipe
Grease trap position and vent stack stub to block sewer odour entry
Gas supply stub-out to cooker position run before wall cladding closes
Supply and drain stub prepared at the right height for the water heater
Recorded pressure test on all supply lines before any wall is closed
How we work

Tell us what is happening and where, and the right equipment is loaded before we arrive.

We film the line from inside and know the kind of blockage and its exact place. No guessing.

High pressure water, a machine or a drain snake, whichever the line actually needs.

The camera runs a second pass and you see the line clear with your own eyes before we leave.
Same method, same equipment. Only the size of the job changes.

Amana means trust. Someone else's home is not ours to be careless in.
Do not take our word for it. Look at the line yourself.
Breaking is the last resort, never the first step.
A blocked line does not wait for the morning.
Six governorates, 139 areas.
For buildings and complexes, servicing before the problem starts.
Restaurants, offices and complexes, not only homes.

Yes, if the main supply exceeds four bar we fit a pressure-reduction valve at the kitchen inlet. This protects hoses and fittings from stress and regulates flow stability.
It is better to fit a grease trap in the waste line to stop fat blocking the pipes. The grease trap needs cleaning every two weeks, after which clean water flows to the tank.
