External drain chamber - manhole cover

[cyberbub]

Hi all, I had an original cast-iron manhole cover over my foul drain chamber, in my garage. This cover broke (cast iron is brittle...) and I want to replace it. The original cast-iron frame seems to be in reasonable condition, and well fixed into the rebate round the top of the chamber, so I'd prefer to re-use it rather than knocking it out and having to re-cement a new frame in etc etc. Is it possible to find a modern eg. galvanised steel, direct replacement for the cover only, which will fit over the 'lip' of the existing frame? I've tried but not having much luck! Seems weird that no-one else would seem to find this an easy solution and someone would supply them?!

Thanks for any info.

(See photo of the existing frame - the chamber is a standard 600 x 450mm 'opening' but obviously the lip on the frame means a new cover would have to be approx 10mm wider in every direction).

Have you thought about eBay, or here for a possible replacement in cast iron, or do you want steel?

If not, might be one for @HERTS P&D or @Hugh Jaleak.

Have you tried wickes?

It'll be more by luck than judgement if you find something to fit, but even then I doubt it'll seal as well as the original cover. Also the issue of loading, thin steel covers will soon bend if any sort of weight passes over them. To be honest, you'd probably be better off biting the bullet and replacing cover and frame with something suitable for the location, if vehicular traffic is going over it, then something capable of taking the loading.
