Plumbing Installation & Maintenance

First-fix plumbing means laying supply and drainage networks before plaster and tiles according to a layout that sets routes, diameters and slopes, then pressure-testing the network before closing it up. The service also covers installing heaters, mixers and pumps, maintaining existing networks and repairing leaks. Most costly plumbing problems trace back to untested installation or incorrect drainage slopes.

When do you need plumbing installation & maintenance?

  • Weak water pressure on upper floors or at certain outlets
  • Hidden leaks inside walls and floors
  • Drain odours and recurring blockages
  • Heaters that fail or don't deliver enough hot water
  • Pumps that run constantly or make disturbing noise

Early warning signs

  • Sound of running water with all taps closed
  • Water meter turning with no consumption
  • Odours from drains and basins
  • Damp patches around bathrooms and kitchens

Materials and systems we use

Material / systemUse and advantages
PPR supply pipesHeat-fused and widely used for hot and cold water lines; the pressure rating is chosen per line.
uPVC drainage pipesFor drainage and vent networks with proper slopes and cleanouts where needed.
Valves, mixers and sanitary fixturesChosen for network pressure and type of use, and installed after the network is tested.
Water heatersStorage or instantaneous heaters sized by number of users and outlets, with a safety valve and earthing.
Pumps and float valvesA booster or transfer pump depending on building height and tank layout, with its operation set up.

How Azl carries out the work

  1. 1Inspect the site, review the layout and set supply and drainage points and heater locations
  2. 2Lay supply and drainage pipes along the specified routes, diameters and slopes
  3. 3Pressure-test the supply network and water-test the drainage before closing up
  4. 4Photograph pipe routes before plaster and tiles
  5. 5Install heaters, mixers, sanitary fixtures and pumps after finishing
  6. 6Commission the network and check pressure, drainage and that there are no leaks

Saudi Building Code

The Saudi Plumbing Code (SBC 701) sets requirements for supply, drainage and vent networks and sanitary fixtures, including testing networks before they are covered.

Warranty and compliance

You receive a written warranty whose period depends on the insulation type and surface condition, with a handover report documenting materials and tests (flood, adhesion, thickness).

Plumbing Installation & Maintenance: frequently asked questions

Why must plumbing be pressure-tested before tiling?

Because any defect in fusion joints or fittings shows up during the test and is easy to fix, whereas finding it after plaster and tiles means breaking and refinishing. The supply line is pressurised and monitored for a set time to confirm the pressure holds.

What causes weak water pressure on upper floors?

Usually relying on gravity from a low roof tank, an unsuitable pump, small pipe diameters, or clogged valves and filters. The fix starts with finding the cause and may involve installing a booster pump or rerouting the line.

Are PPR pipes better than older types?

PPR pipes don't rust and are heat-fused, so they have fewer leak points than older metal pipes with threaded joints. But their quality depends on choosing the right pressure rating and accurate fusion.

What size water heater does a home need?

It depends on the number of users and bathrooms and the usage pattern. Storage heaters suit simultaneous use, while instantaneous heaters suit distant or low-use outlets. What matters is fitting the safety valve, earthing the heater and connecting it to a suitable electrical circuit.

How do I know if I have a hidden leak?

Close all taps and watch the water meter; if it keeps turning, there is a leak. Its location is then pinpointed with leak detection equipment without random breaking, and only the damaged section is repaired.

What causes drain odours?

Common causes: trap water drying out at unused outlets, no venting in the drainage network, incorrect slopes causing standing water, or a leaking joint. The fix depends on identifying the exact cause.
