NEW EUROPEAN STANDARDS(EN STANDARDS)COSMOPLAST uPVC drainage pipes and fittings are manufactured and tested in accordance with the new British - European Standards BS EN which have replaced the old British Standards for drainage applications. The new BS EN standards cover all the sizes and applications of the BS Standards.
BS EN 1329 : 2000applies to uPVC piping systems for soil and waste discharge (low and high temperature ) within the building structure. This standard replaces the British Standards BS5255 and BS4514. Products made to BS EN1329 are fully compatible with the products made to BS5255 and BS4514.
BS EN1401-1:1998applies to UPVC piping systems for underground drainage and sewerage. This standard has replaced most of BS4660 and all of BS5481. Products made to BS EN1401-1 are fully compatible dimensionally with the products manufactured to BS 4660 and BS 5481.
Cosmoplast Underground and Above Ground Drainage Pipes & Fittings are approved by the British BSI and are awarded the Kite Mark Quality Certificate where applicable.
3SOLVENT CEMENT JOINTING
To achieve effective reliable joints:
Ensure that all pipes and fittings are cleaned with cleaning fluid before applying cement.
After applying liquid weld (solvent cement), initial bonding is achieved within 15 seconds. However, the joint should not be disturbed for 10 minutes.
CAUTION:Closely follow directions for use of solvent cement as printed on the container label.. ENSURE GOOD VENTILATION OF
Cut the pipe square, de-burr and clean mating surfaces with Cleaning fluid using a dry, clean, natural fibre cloth (not synthetic).
Coat mating surface with liquid weld (Solvent cement), using a clean brush. Replace lid on container to prevent evaporation of cement.
Assemble joint immediately with slight twisting action, removing any excess cement with a clean rag. Initial set: 10 minutes. Final set: 12 hours.
Jointing TechniquesPUSH FIT JOINTING
File square cut pipe to provide 15 chamfer. (Do not chamfer to a knief edge).
Lubricate rubber seal with suitable lubricant.
Step 3Push pipe fully into socket.
Step 4Withdraw the pipe 5-10mm to allow for expansion.
CUTTING THE PIPES
While cutting Cosmoplast uPVC pipes, the following instructions should be followed:
Appropriate pipe cutter or saw should be used.
Cut pipes square and perpendicular to its axis.
After cutting pipes, remove all burrs from the cut end, and bevel the sharp cutting edge.
4SOUND INSULATIONIn order to achieve optimal sound insulation it is highly recommended to consider the local building regulations and codes where applicable.
Waste pipes should not be projected in living, sleeping and working rooms. Whenever waste pipes are required to be fixed on walls adjacent to living and sleeping rooms, the construction of those walls should be particularly constructed with specific weight of at least 220 kg/m2.
The same requirement is also valid when installed in a shaft and fixed on the intermediate wall. The pipes must be free from the plaster layer, avoiding eventual sound bridges by either using appropriate pipe support with rubber lining or by wrapping a layer of mineral wool around the pipe.
It is recommended to prevent abrupt directional changes when changing the flow direction on long pipe installations. In such cases, it is recommended to change the direction from vertical to horizontal by using two 45 elbows interconnected by a short piece of pipe with minimum length of 25cm instead of using one 87 elbow.
It is always recommended to use clamps with rubber lining for fixing the pipes for optimal sound insulation.
Trapped Floor GulliesINSTALLING FLOOR TRAP
Check overall height of unit with inlet in position, and adjust to suite installation location. (Do not solvent weld at this stage.)
Step 2:Place gully into position.
Step 3:Solvent-weld waste pipe to outlet socket.
Step 4:Bring floor screed up to level with bottom of gully inlet.
Step 5:Allow screed to set, and remove gully inlet.
Step 6:Apply waterproof masrtic to underside of square flange of gully inlet.
Step 7:Solvent cement gully inlet into position.
Step 8:Tile up to inlet, and grout using waterproof grout.
5SUPPORT AND EXPANSION
All pipework must be adequately supported whether vertical or horizontal.
Plastic pipework expands and contracts with changes in temperature - whether ambient temperature or from the nature of the discharge through the pipework. Expansion joints must therefore be provided to accommodate such thermal movement.
Pipe brackets must be used to anchor expansion joints. Intermediate support must also be provided to steady pipework between the points.
Horizontal pipework requires more frequent support than vertical pipework (for example, soil stocks)
On long suspended soil pipe runs (e.g. in basement areas), sliding joints should be installed to control the effects of thermal expansion.
Pipework should always be supported close to anychange of directions (e.g. bends or branches)
Cosmoplast uPVC drainage pipes and fittings should be installed tension free and with free lateral allowance for thermal expansion compensation.
Suitable sound absorbing brackets with rubber lining should be used to support pipes. Those brackets must be dimensionally compatible to the pipe diameter. The fixed bracket creates fixed point in the pipe system.
With fixed brackets the pipe or fitting can not be moved through the bracket after screws are tightened. In order to prevent sliding down of vertical pipes, each individual pipe must be secured on one point by a fixed bracket.
Every horizontally installed pipe should always be fixed with one fixed bracket. All remaining pipe brackets in horizontal as well as in vertical installation must be tightened in such a way to allow sliding.
During installation of horizontal pipes, the bracket distance should be approximately ten timed the outside diameter of the pipe. While for vertical installations, brackets are required every 1 to 2 meters depending on the size of the pipe.
Pipe brackets should not be installed in areas of diameter reduction and change of directions in the system, this is required to allow for the thermal expansion.
Pipe brackets should be fixed on building materials with high strength in order to assure strong and durable pipe fixing.
Fixed brackets must be installed directly above the fitting at the bottom of the pipe end. The sliding bracket must be installed at a distance of maximum of two meters above the fixed bracket.
In multi-story buildings, the drainage pipes of diameter 110mm or bigger installed inside the mechanical ducts must be secured by additional fixing against sliding.
MAKING SOIL PIPE OFFSETS ON-SITEThis connection is required to offset soil pipe run (e.g. to by-pass a gutter), and can be easily created on-site with a length of soil pipe and bends.
Step 1: Measure projection (P) required to take pipe past obstruction.
Step 2: Determine length of pipe required, noting minimum offsets possible.
Step 3: Square-cut pipe length and de-burr cut ends.
Step 4: Solvent-weld or Push-Fit into standard bend or offset bend sockets.
Vertcal Installations can be done in two ways:
a) Fixed Installation b) Free Installation
In horizontal Installations, pipe clamps should be placed at intervals which are approximately ten times bigger than the pipe diameter. This will insure that the installation is fixed and will not bend.

Technique (1) Technique (2) Technique (3)
Ventilation is essential in every drainage system. In order to prevent traps being emptied by suction or pressure, both overpressure and underpressure should not exceed 300 Pa (30 mm water column). Air should be able to escape from the system (venting) and to enter the system (admittance). A ventilated discharge pipe is used for this purpose.
Ventilation Valves must be installed in a vertical position above the flood level of the high
