We need a manhole cover in the middle of our kitchen floor (I won`t go into all the details why) but basically we are committed now.

I have found a man hole cover which are recessed so I plan to fill the lid of the manhole cover with concrete and vinyl the whole of the kitchen floor.
I think this would look ok, Im just seeing if anybody has any better ideas ?

We have to have a sealed manhole cover on it, as the drain is being used for the sink, dishwasher and washing machine and so if its not sealed correctly will start to stink.

Any ideas, or experience of the above. Does it look really bad having a man hole cover in the kitchen floor ?

I'm pretty sure it's illegal, as manhole covers require access.

Concrete's not too accessible

Correct me if I'm wrong.

I also understand that manhole covers need to have access at all times. If you are going to cement it over then don't tell anyone and make sure it's not on your existing plans.

My dad did this once and was forced to dig up the front room (after installing underfloor heating) after a building inspector found out!

Sorry, I probably didn`t explain very well.

As I understand it, you cant block man hole covers up, and I wouldn`t want to as if there is a blockage I would be stuffed.

You can buy man hole cover that sit in a frame, and the cover part of it is recessed. So I fill the recess of the cover with concrete.

I have seen these work quite well with Tiles but never seen it done with vinyl.

I would say you really need something with a watertight seal.
It's not at all uncommon for these access ducts to fill to the surface and over flow.

The proper solution is to dig it out and put a new one in outside. It is a lot of work, but you don't have to demolish the building to do it.

I have the same issue with our kitchen extension. Existing inspection cover would have been in the kitchen. Build regs stated that we had to have a bolted and sealed inspection cover put over existing which was built up to floor level.

The cover you linked too looks fine for this purpose (but I'm not a building inspector smile )

After digging it out to see the soil pipe runs to ours (not likely you will do this I guess), I've had to move it completely instead. Expensive, but a lot less than digging up the kitchen if your soil pipe fractures and you don't want a stinky house do you? wink

Would be interested to see a pic of the drawing showing the proposed drainage layout .

Sealed bolt down cover and frame are fine , though not desirable anywhere in the house.

I suspect to get a decent finish on the vinyl ,you will end applying a laytex compound over the whole frame and cover .

You need a double sealed cover, have a look at the howe green 3500 series (small access, might need to go bigger though) they are what we use internally when we spec internal chambers.
