MASTER 3 PLUS | Plastic


The exclusive MASTER 3 PLUS sound-insulating drain system from SANHA consists of high-quality three-layer pipes and modern fittings. The drain pipes are constructed with three perfectly matched layers that work together to meet all the demands that a drain system is subjected to in the construction of a modern house, apartment and industrial building. Each layer optimises the properties of the pipe: The smooth inner layer prevents encrustations and is partly responsible for the good sound insulation properties. The solid middle layer is extremely robust and the brown outer layer provides excellent impact resistance even at low temperatures. The sealing ring consists of styrene-butadiene rubber (SBR).

Easily compatible

MASTER 3 PLUS is easily compatible with HT-pipes due to the spigot and socket system.

Extensive flexibility

Many sizes between 32 and 160 mm available.

Chemical strength

Resistant to acids and alkalis in the range of pH 2 to pH 12.

Higher impact strength

The MASTER 3 PLUS drainpipes meet the more stringent requirements for impact strength and are therefore also suitable for installation at temperatures below -10 °C.

Practical pipe protection

Pipe protection from water repellent polyethylene foam with red durable and shatter-proof outer skin and inner gliding foil, sound-insulating.

Low linear expansion

Excellent sound insulation

The technical sound-insulation properties of the MASTER 3 PLUS drain system by SANHA have been tested by the Fraunhofer Institute in accordance with DIN EN 14366 and it meets all the requirements of DIN 4109 for sound insulation. The installation noise level is between <10 and 23 db(A)*.

Proven fire barrier

With the MASTER 3 PLUS, SANHA provides a domestic drain system, as a stand-alone system or in combination with other SANHA pipeline systems, which complies with standards and offers a practical solution for all standard applications in building technology with regard to fire protection. We recommend the tested and approved DOYMA Curaflam ECO Pro fire protection cuff, which also allows zero clearance installation, as a fire barrier.

Simple floor slab and wall ducting

SANHA MASTER 3 PLUS can be easily routed through both solid and light partition walls as well as through slabs. 

Easy mounting

Many sizes between 32 and 160 mm available.
