Naturally, HT Safe^® is fully compatible with our previous HT system.

Patented 3 lip seal

The new patented 3 lip seal can now be used more quickly than ever before and guarantees secure sealing even under the most adverse conditions.

Minimum noise emission

The smooth inner wall ensures optimised noise behaviour of just 21 dB (at a 4 litre flow rate according to measurements with Bismat 1000 (P-BA 222/2016)). This makes the in house waste water system extremely quiet and offers excellent soundproofing.

PP-H formula

The pipe is made of polypropylene and is hardly inflammable according to DIN 4102 (B 1) and DIN EN 1451-1.

25-year guarantee

We offer an unbelievable 25-year guarantee on this system. The resistance, formula and a patented 3 lip seal completely redefines the standards for building drainage.
