Turning on the Tap *Sods Law


Sod's law => the theory that if something can go wrong it will go wrong

I was very happy to aagin have mains water The next two steps were to flush out the new water pipe and then to isolate the old valve and  then finally open the valve to allow the mains water into the house
.

The picture on the left shows   from bottom to top the different taps now installed in the garage. 

Firstly we have the stopcock to isolate the external supply

Secondly we have the drain with small square tap to flush the new mains pie,
Thirdly an isolating valve to prevent any dirty water from entering the system
Fourthly a non return valve to ensure that there was no risk of water being sucked back during the flushing operation
(gets complex does n't it)

So having isolated the old mains tap inside the house  I made sure the isolating valve was off I connected my green hose to the drain and let the water run for around 10 minutes to ensure all traces of grit were gone,I then closed it off , opened the isolating valve and went inside to check the water - No water.

After various attempts - I thought it could be an air lock - I gave up and called Gary the plumber who investigated and discovered that he had fitted a one way valve that did not work - the reason it did not work is that the manufacturer had inserted the one way valve the wrong way .
If you look at the non return  valve in the close up picture you will see  an arrow pointing up this indicates the direction the water is able to flow, but as the valve inside had been fitted the wrong way in fact it stopped the water all together.
Gary removed the valve turned it round and fitted it the "wrong way" and the result was now everything worked.
Gary also tested the pressure which was around 3 bar so this means that we have a good connection to the water main.
So quite an epic
Thanks again to Gary for his quick response and speedy identification of the problem
