Testing New Stack Pipe

[charliefunkuk]

The council have to come out to see a test on my new stack pipe I have installed on my extension. What does this involve? Do I just cap off the inlet in the manhole and fill the stack pipe with water and cross my fingers while the council man looks on???

Thanks for your help.

I`d cap the top of the stack too

if I cap the top of the stack how are they gona see the level of the water if it falls? I currently have nothing attached to the pipe and I thought that was how it had to stay till council passed it off?

Never been present when council have tested but the checks required are a soundess & a performance test. Pipework should be temporarily plugged & air pumped in to a predetermined pressure. It is left to stand for a short period & any loss of pressure noted & if it drops a leak is present & should be repaired.
This is a soundness test. The performance test requires an adequate water seal be retained in all traps, when all appliances are discharged. The minimum depth is 25mm.The appliances should be discharged 3 times & if any fail to retain the required depth of seal the installation is deemed to be unsatisfactory.

Knowing the council they will just take a dump on your crapper,( did you know that he invented the toilet)? flush it & if it disappears tell you it`s sound & waltz off.

They can ask for a air test but what they usually get unless its a fresh inspector is ,

Bag/plug top of stack
Bag plug base of stack
Flush toilet ,level rises and they watch it for a while ,talk over a few bits etc then check the level again ,meet one who put a piece of paper floating in the bowl to check for current in the water.


But with nothing attached it will have to be air test and plugs on everything

It's a proved way of checking for leaks although I tend to use a match.
