Its the weekend
Well the weekend is meant for rest and recuperation but not for me .. I am expecting Thames Water to come Monday afternoon to conect my new 25mm pipe that replace my 12.5mm pipe, so I thought I had better check out the regulations

Here you see that water pipes must be 750mm below ground that is  30" in imperial. As the new drive will go on top of the trench I do not have to dig as much as that, I estimate that the blocks 75mm plus sand 70mm, plus scalpings layer75mm (225mm) means I have to dig a 525mm trench I dulymeasured my trench and discovered it was nearer to 300mm this meant lots of digging this weekend to be ready for Thames Water on Monday - they have the right to check the pipe preperation and refuse to conect if its not in line with their regulations (above)
Here I am with an almost finshed trench.

Between yesterday and today Ihave filled the large yellow bag (1 cubic metre) with chunks of chalk I have also riddled out fine bits of chalk to mix with the sand to line the pipe before its burial
So Finally after a lot of digging  I have broken the

500 mm depth barrier so I assume the man from Thames water will be happy to connect the new Blue pipe - What is odd is to see our existing water pipe 12.5mm copper hanging in the air by tomorrow evening it should be gone.
 Below you will see the pipe in the now deeper trench waiting to be connected tomorrow 
The other thing scheduled for tomorrow is the re-routing of The main supply pipework in the house - You may remember that we have installed a new mains water stopcock in the garage  (stopcock) this now needs to be reconnected to the existing pipework in the house. Our favourite Plumber /gas central heating engineer is coming to work out how we should do this - It will be interesting
