House introduction

Multi-line building entry with water, electricity, telephone and speed pipe for fiber optics

House lead-ins or wall lead-throughs are components that allow different pipes for gas ( gas house lead-in ), drinking water ( water house lead-in ) or district heating as well as cables for electrical power or communication (telephone, TV, etc.) to be safely inserted into buildings. House entries are part of the house connection and must be tight against gas and water.

General

House entries are divided into single entries and multi-branch entries. Individual introductions are usually used to introduce one division at a time, for example gas, water or electricity. Multi-line entries bundle several or all of the pipes and cables required for electricity, telecommunications, fresh water as well as gas or district heating and feed these together into the building.

Installation

A distinction is made between dry and wet paving. While the building entry is detachably sealed with at least one rubber press element to the building with dry installation, with wet installation the building entry is firmly and permanently connected to the building using a hardening potting material.
In addition to sealing the building entry to the wall or floor slab, the connection of the building seal to the building entry may also be relevant, depending on the situation. For this purpose describes z. B. DIN18533 different requirements and types of execution.
