Plumbing and hot water in Morocco: mandatory pipe standards, gas safety and tests

Plumbing is the finishing package with the densest set of mandatory Moroccan standards. Supply pipes in PE, PVC-U, PP-R, PB, PE-X and multilayer, copper fittings, PVC-U and other plastic drainage pipes, flexible hoses, water heaters and gas pressure regulators all carry mandatory NM references. Gas appliances also fall under Order No. 1616-22, and water use under Law 36-15 on water. Connection to the public networks follows the local distributor's rules. The two tests that matter on site are the pressure test of the supply and the flow test of the drains, both done before walls and floors are closed.

Scope

This page covers cold and hot water distribution inside the plot, drainage of waste and soil water down to the inspection chamber, rainwater pipes inside the building, electric, gas and solar-assisted water heaters, and the domestic gas installation up to the appliances. Sanitary fixtures and taps are treated in their own package.

It runs from the services design approved with the drawings to the commissioning of every water point and the final connection to the distributor's network. Buried mains and sewers outside the building belong to external works; solar collectors and their circuit are in the solar package.

Common non-conformities and follow-up

FindingAction
Supply pipe without visible marking or of a material not in the specification.Removal of the unmarked lengths and replacement with conforming pipe from a single system.
Pressure test not performed, or performed after tiling.Test carried out immediately; if a leak appears, opening of the finish, repair and a new recorded test.
Drain falls too flat, causing standing water.Re-laying of the section concerned before the floor is screeded.
Gas water heater installed in a room without ventilation or proper flue.Appliance put out of service until the ventilation and flue are corrected or the heater is relocated.

Frequently asked questions

Which pipe standards are mandatory in Morocco?

The main plastic supply pipe systems (PP, PE-X, PB, multilayer, PE, PVC-U), PVC-U drainage pipes and copper fittings all have mandatory NM references listed in the catalogue.

Who connects my house to the water network?

The local distributor, according to its own connection conditions. Your plumber prepares the branch and the chamber as the distributor requires.

When must the plumbing be tested?

Before closing: under the slab for buried drains, and before plaster or tiles for pipes in walls and floors. Tests done after finishing are of little use.

Are gas appliances regulated?

Yes. Order No. 1616-22 regulates the safety of gas appliances and equipment, and several gas standards are mandatory, including those for regulators and gas water heaters.

What documents should I keep?

The plumbing drawings as built, the pressure and flow test reports, and the conformity documents of pipes, water heaters and gas devices.
