Week 47, Day 5:

• Quite a lot of progress on the second-fix, plumbing:
  • Checking all the pipe connections inside the house, before…
  • Connecting the mains water supply outside
  • Filling the DHW tank, manifolds and heating circuits to bleed the air and check for leaks
  • Completing the installation of the last shower and towel radiator
• A little more work on the drainage, roughly setting out to the north and west of the house
• More work on the lighting, installing additional DALI-dimmable LED drivers and adding some KNX programming so that lights come on when triggered by PIRs, for example in the Utility Room and the Entrance Hall
• Installation of the outlet plates in the floor boxes in the Living Room

Week 47, Day 5

Water main connection

The 32mm mains water connection comes in from the bottom-left and exits to the new house at the the top-right. The black (actually black with a green stripe) pipe which also exits at the top right is the separate supply which might in future get switched to a rainwater harvester, supplying WCs, outside taps and the washing machine. The narrow blue pipe on the left is the temporary supply to the site cabins and the disconnected black pipe on the right was the connection to the old farmhouse. The temporary supply to the static caravan is fed from another tee off the 32mm main, buried out of shot on the bottom-left.

(The  main water pipe is only 15mm diameter at the meter, but that’s 600m away so the pipe is 32mm / 1.25″ to minimize the pressure loss over such a long distance. Severn Trent Water have a higher standing charge for a 22mm meter – and more again for a 32mm meter – but 15mm is adequate for a house and the pipe only reduces to 15mm for a short distance.)
