    Man holes and their covers.

    I have had a partially blocked kitchen drain for quite a while and, at last, cleared the pallet piled up with wood that was over the manhole cover closest to the blocked drain (kitchen outflow/gutter downpipe). I had thought that the blockage was up near the kitchen outside U-bend and was intending to try to water jet up from the other side of the blockage.

    The manhole cover was corroded to the frame and took some time to free up. When I was able to remove it I was somewhat surprised to find a sheet of plastic 'board' in the cistern and it must have been there since ??????? When I say "board" it is more akin to 'floor' in the bottom of a collapsible dive/sports bag.

    Anyway, it was pretty gross because it was slowing the inlet from the kitchen/gutter pipe into the cistern and I assume that it's braking effect on the waste flow was sufficient to aid the build up of a fairly long fat-plug. Also, toilet inlet is in that cistern so I didn't stop to measure it as I removed it (whilst wishing I had longer arms and a clean glove to pinch my nose/it's a wonder I wasn't sick) - it was originally oblong (maybe 1' * 2') but had curled into a tube shape.

    I wondered if it was supposed to be some sort of inner cover to prevent unpleasant odours wafting up but it didn't seem to be the right size.

    I suppose it might have been put in there to stop pug getting into the drains when building works were going on and forgotten about?

    Anyway, I was curious to know if it was a proper part of the cistern/manhole cover setup or a mystery?

    It will probably be a sheet of plastic packing (korex / antinox). Looks like plastic corrugated cardboard. Used for packaging of paving flags etc.

    Whoever was working on the manhole cover/frame may have cut it to size put it in the base of the manhole to stop mortar/debris/sand ending up in the channel of the drain whilst they were pointing it up. They have never bothered to remove it.

    Bin it.

    I can't think why there would be a plastic 'board' in a manhole. The covers are usually made of either cast iron, galvanised steel or plastic (depending on size and loading).

    You might be right that someone left it in there as something 'temporary' and forgotten about.
    The major difference between a thing that might go wrong and a thing that cannot possibly go wrong is that when a thing that cannot possibly go wrong goes wrong it usually turns out to be impossible to get at or repair.

    Also, did your phone ring whilst you were gloved up - about 15 seconds after you put your hand into the "liquid".

    Definately should not be any sort of board in an inpection chamber (not PC to call them manholes anymore don'tcha know). Sounds like lazy or forgetful builders.

    There should be no additional need to seal the chamber from smells as the cover should do that job. If it is not due to corrosion, it should be replaced.

    One tip I was given years ago for working with drains - have some Vic vaporub and apply it liberally to the top lip - you then smell that instead of the crap. It does work. Even without it, you will find that you get used to it in about 15 minutes. After that you will probably not smell it.

    You should experience monkey poo that's been in a warm sample pot in the post for 3 days - nothing would stop that getting through! The long dead monitor lizard was a close second though...
