Traditional Express Cast Iron Push Fit Soil System Pre-installation
Traditional Express sockets, both plain and eared are designed only for use with Traditional Express pipes and fittings.
Design of the soil stack should allow at least one eared socket on each fitting to enable the system to be anchored securely to the building.
Installation should proceed from bottom to top of the soil stack with typically a length of pipe, boss pipe or branch at the base of the stack. This first pipe/fitting should be connected to the underground drainage system to ensure a secure base and have an eared socket fitted to the top to ensure stability and security of the pipe work before proceeding further.
Subsequent pipes/fittings installed vertically above this point should incorporate at least one eared socket. On branch arms we suggest the use of a plain socket to provide the correct aesthetical appearance
The assembled joint is designed to be a tight fit to ensure compliance with a pressure test and long life performance.
Push Fit Cast Iron Soil Installation
In all assembly operations it is essential for the gasket and corresponding pipe / fitting area to be fully lubricated to enable insertion of pipe / fitting into a Traditional Express socket.
1 To aid insertion of the components, immediately prior to assembling any joint, pre-relaxation of the rubber gasket is recommended. Apply a small amount of lubricant (TX0001) to the rubber gasket/s and insert the gasket relaxing tool (TX0002) into the joint. Slide the relaxing tool up and down over the gasket sealing face three or four times. The gasket will now be temporarily softer and enable easier assembly of the soil stack joint. Caution. Do not over insert the relaxing tool past the rubber gasket.
2 Apply a small amount of lubricant (TX0001) to the rubber gaskets at both ends of the push-fit socket. This is necessary to ensure the insertion of pipes and fittings into the socket.
3 Push the socket over the end of pipe after lubricating both pipe and gasket ensuring pipe end is fully inserted and abutting central register in the socket.
4 If the socket is eared, securely fix to wall using corrosion resistant coach screws (R0005) or similar.
5 Push the next pipe / fitting into the socket checking that it is fully inserted and abutting the central register. Repeat the above process on remaining joints until stack completed.
6 When cutting into an existing cast iron soil system, a slip socket with ears should be used (TX4016SE). This has no central register and allows the socket to be slipped onto the existing pipe up to the second gasket, before placing the new fitting in position.
7 Next slide the eared socket into the correct position where the respective gaskets make a seal on the pipe / fitting on either side of the joint.

Benefits of Cast Iron
Cast iron is particularly well suited for all drainage systems as it offers many benefits, both for above and below ground installation, which include:
Strength and durability - cast iron is able to withstand the rigours of on-site handling, mechanical de-blocking and vandalism and requires less embedment than other materials for below ground Installations.
Long life - when correctly installed cast iron drainage systems will last the life of the building, whether domestic, public, industrial or commercial.
Low maintenance - cast iron requires little on-going maintenance, annual inspections are recommended but remedial action is rarely required.
Design Capability - cast iron can meet the needs of restoration, refurbishment, conservation and heritage work as well as new, bespoke and unique designs.
Sustainability - in addition to lasting the life of a building and requiring minimal maintenance, cast iron is also 100% recyclable and can therefore be used again after the building has gone.
Cost effective - owing to its longevity, durability and low maintenance, coupled with its fire resistance and low noise operation, the cost benefits of cast iron are significant.
Fire resistance and Safety - The melting point of cast iron is considerably higher than PVCu or PE and in the event of a fire will not emit toxic fumes or drop burning globules of material from one compartment to another.
