The pressure is on

The two ground loops have successfully been put in place and tested.
The system was bled to ensure there was no air before being tested.
Each loop has been pressure tested up to 4 bar and sat at that pressure for 20 minutes, until we were sure the system was leak free. This is part of the formal procedure: paperwork recorded times and pressures and signed of.

Saturday morning after the pressure testing the digger driver was back at work to fill in the trenches. He then went on to do some grading and landscaping around the drive.
