European foreword
This document (EN 1253-6:2022) has been prepared by Technical Committee CEN/TC 165 “Waste water
engineering”, the secretariat of which is held by DIN.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by April 2023, and conflicting national standards shall be
withdrawn at the latest by April 2023.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
Within its program of work, Technical Committee CEN/TC 165 requested CEN/TC 165/WG 11 “Gratings,
covers and other ancillary components for use inside buildings” to prepare the following standard:
EN 1253-6, Trapped floor gullies with a depth of water seal less than 50 mm.
The EN 1253 series under the main title Gullies for buildings will actually consist of the following parts:
— Part 1: Trapped floor gullies with a depth water seal of at least 50 mm;
— Part 2: Roof drains and floor gullies without trap;
— Part 3: Evaluation of conformity;
— Part 4: Access covers;
— Part 5: Gullies with light liquids closure;
— Part 6: Trapped floor gullies with a depth of water seal less than 50 mm;
— Part 7: Trapped floor gullies with mechanical closure;
— Part 8: Trapped floor gullies with combined mechanical closure and water seal.
Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia,
Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland,
Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of North
Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Türkiye and the United
Kingdom.
1 Scope
This document classifies floor gullies for domestic waste water for use inside buildings, gives guidance
for places of installation and specifies requirements for the construction, design, performance and
marking of factory made gullies for buildings, irrespective of the material, for use in drainage systems
requiring a trap with a depth of water seal less than 50 mm (referred to as floor gullies).
NOTE Floor gullies with a depth of water seal less than 50 mm are not covered by EN 1253-1, EN 1253-7 and
EN 1253-8.
These products are intended to be installed where the three following conditions are met:
— space limitation will not accommodate a gully with a 50 mm water seal;
— the building does not exceed a ground-floor and three floors above;
— at least two domestic sanitary appliances are installed in addition to the gully but with only one WC
on the same branch (connection pipe) or secondary or branch ventilation is installed (see
EN 12056-2:2000, 4.3.2 or 4.3.4.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in EN 16323 and the following apply.
3.1
trapped floor gully
discharge fitting the top of which is a grating or cover capable of installation at ground or floor level,
intended to receive wastewater either through apertures in the grating and/or channels joined to the
body of the gully and to drain that wastewater through the outlet
Note 1 to entry: Four generic types of floor gullies are shown in Figure 1.
Note 2 to entry: In this document, the term “trapped floor gully” includes linear products, such as channel drains.
a) Floor gully with flange for bonding b) Floor gully with flange for clamping
waterproofing membranes (example) membranes (fixed and loose flange)
(example)
c) Floor gully with flange for clamping d) Channel drain with flange for bonding
flexible flooring (e.g. PVC flooring) (example) liquid applied membranes (example)
