Frequently Asked Questions
BS EN 12056-2:2000 requires that traps discharge to a soil stack with a 75mm seal however other water seal depths can be installed as follows:
- 50mm Water Seal - Can be fitted to baths, shower trays and basins with spray taps and no plugs.
- 38mm Water Seal - Can be used on the ground floor when connecting to flat bottomed appliances that discharge to a back inlet gully.
Siphonage occurs when negative pressure draws air into the waste pipe as the wastewater from a bath or basin discharges and pulls the water seal from the trap with it. There are three types of siphonage:
- Self-siphonage - discharge from an appliance causing a loss of seal in its own trap
- Induced siphonage - the seal loss is because of the discharge of another appliance connected to the same waste pipe
- Compression siphonage - a falling body of water in a vertical pipe compresses the air below it and forces the water seal from lower appliances traps.
In some circumstances, where siphonage is occurring because of the pipework arrangement, but secondary ventilation is not possible, it is advisable to use a resealing trap. By drawing air in through the waste outlet before the water seal is dispersed, it counteracts siphonage before it can threaten the seals' integrity.
However, resealing traps can be noisy and do not completely eliminate water seal loss. To prevent this, the Multikwik anti-siphon unit allows air to enter the waste system as pressure drops while wastewater discharges.
You will need to measure the outer diameter of the spigot from your WC pan and also the inner diameter of your pipe, then take a look at the dimensions provided for the individual connector to find the best match. Details for all pan connectors can be found on our website or literature.
