We are currently installing A number of services above ground in a gantry construction in the CTA area of Heathrow Airport

Test procedure for such pipework is a little complicated due to the elasticity of the product

All our test results to date indicate too much air in system

Since pipework is above ground we are able to inspect all joints and can confirm the system is sound and no leaks exist

I've asked for Guidance from WRC , the creators of the test procedure , to ask if we can infer the tests have passed since we know of no leaks

WRC , have refered me to this forum

Can anyone help ??

Any advice would be very much appreciated

Many Thanks
