Hi All,
Job number 671 has reached the front of the queue. The main bathroom.
It was gutted 7 or so years ago and is now on the hit list.

First slight problem is, in our downstairs hall-way (built on a hill so
one side is underground) which is the bedrooms and main bathroom there
is an inspection chamber "collector" fed from the upstairs dirty water,
a clay pipe from one end of the downstairs bathroom and a poo pipe from
the other side of the bathroom.

The inspection chamber "top" is a double lipped frame packed with grease
into which the single lip of the heavy chamber lid nestles and is then
fixed down by 3 (originally 4 but one is sheared off) large brass screws.

Having such a lovely beast in the hall between bedrooms I'd prefer to
replace it with something more "modern" that doesn't rely on loads of
grease to make a gas/excrement/fluid seal but still needs to be
mechanically locked in place should the outlet become blocked and sh1t
backs up flooding the hall.

Current steel lump is 600mm by about 740mm (whatever the imperial size
would have been)

Any suggestions of should I just grease it back up and forget all about
it.. ?

Cheers
Pete

Update - on further investigation it's the "clear open space" or such
that I should be measuring i.e. the hole, which comes into the realms of
450 x 600 so now I'm back on track...

Speaking from a large degree of ignorance, I would doubt that such a
beautiful, reliable and strong object could ever be purchased nowadays.
I would check the pointing of the walls of the chamber, replace the
screw (a large brass one should be easy to get out and replace) and be
glad to keep it!

I think newer ones have rubber seals and you can get double lid ones intended for basements with back pressure eg

"All units are airtight and virtually watertight."

That's OK then.....

I'm very surprised its indoors. When the ex neighbours built an extension
they put it over the chamber that was outside. The folks from Building
control made them dig up the floor and the pipework and put it outside
again. A very noisy and dusty and annoying job.

Am I alone in thinking that air, being thinner, would be less
likely to leak through than water, or is it more complicated than
that?

Indeed. Maybe they mean "atmospheric pressure air tight"

I guess it depended if it was a private or Water Board Chamber.

Unlikely you are the only one likely to get that so wrong.

or is it more complicated than that?

Yes it is. Most obviously with PET bottles of stuff like beer.

The CO2 will eventually diffuse thru the PET and the water never does.

And with plumbing, water and **** laden water etc can see
that blocking small unpressurised leaks whereas air doesn't
do that with leaks as much.
