Inpection chamber inside a house - Enclosing an ic within a porch

[Mark Worthington]

Hi there! What a great site!

I am getting a porch built in a 6 year old property. We have discovered a (hidden) plastic inspection chamber, which has 3 pipes feeding in, and one going out. One of the input pipes seems to have a blanking plug, and the other two are fed by different parts of the house.

My first question, please, is to ask whether the blanking plus is normal? Why not use a 2-into-1 chamber?

More importantly, when the porch is complete, the IC will be inside the house!! Is this normal/acceptable? Can anyone advise me of possible alternatives? I imagine that the whole thing can be moved….. ?

Cheers in anticipation,

Mark

The reason for the blanked inlet is that those preformed bases provide 3 inlets and one outlet. Larger units have 5 in and 1 out, but there's no obligation to use all of them. The 2-in-1-out chambers are much smaller, typically 225 or 300mm diameter and as such are not large enough t be acceptable as an inspection chamber - they're known as access chambers.

IC in the house is less than ideal. You MUST use a double-sealed cover if it stays where it is, but I'd give serious consideration to getting it moved so that it stays outdoors where it belongs.
