Abstract

A fluid testing arrangement includes an adaptor/connector 16 which couples to a service pipe 11 to allow fluid passage to continue from the main pipe 10. A catheter 18 is passed through the supplementary connection 17 and through the bore of the adaptor into the service pipe 11 until it reaches the main pipe tee connector 12. A logger 20 senses and measures the fluid pressure in effect, at the main pipe without the need to excavate.
