Ensure pipe sockets and spigots are not damaged. Ensure that integral seals are not damaged and apply the approved lubricant. For pipes without an integral seal, ensure the seal is of the correct size and is not damaged. Position the rubber ring on the end of the spigot. Under no circumstances use lubricants when using seals of this type, as they are pre-lubricated internally.
Ensure each pipe to be laid is aligned with the laid pipeline and is fully supported along its length. The recommended method of joining pipes is shown below.
