Inspection trap and rusted chamber cover

[Paul Cordon]

Hi

I have an old inspection trap which is fed both from my bathroom and outside surface drainage which then enters an old brick inspection chamber. The inspection chamber is then also fed from from both mine and my neighbours toilet foul. The inspection chamber cover is severely rusted because this was concreted over. I have a couple of questions here:

1) am I ok to remove the cover with an angle grinder as there appears to be no other option? No lift points and severely rusted as this was concreted over

2) should the brick inspection chamber be replaced?

3) if the brick inspection chamber isn’t removed I would replace the trap with a single pipe in to the inspection chamber. I presume there is no issue with this is I use a sleeve and seal it?

Any advice would be appreciated

If the inspection chamber serves more than 1 property then ownership and repairs to it, is the local water company's responsibility.
They took ownership in 2011 regardless of the condition of chambers and drains.

You cannot carry out any work within or additions to the chamber without approval from the water company.

Any drains before the chamber serving only 1 property are the responsibility of that property.

Ring your local water company and explain the situation with the Inspection chamber.

Hi Snowhead

Thanks for the reply. Just to be clear I live in Scotland and it’s one property converted to 2 flats. I presume it’s still the local water authorities problem?

Hi Snowhead

I have just called Scottish Water and the transfer of private sewers regs only apply to England & Wales. I have been told that anything that sits within our boundary is our responsibility to repair so my original question still applies.

Thanks

I assume by Inspection trap you mean a Gulley something like this,

Re Cutting up the cover then.

Yes, if there's no way of lifting the cover, you'll need something temporary to cover the hole till a new cover is fitted.

There's nothing wrong with a brick chamber if it's in good condition or can be repaired.

Hi Snowhead

No I mean a Buchan Trap. I intend on replacing this with modern plastic connectors etc with a single pipe feeding the inspection chamber via a sleeve so I can seal it properly. The chamber is backing out foul waste through the trap via a seal leak so I need to get in to the chamber to clear the blockage then replace any damaged pipe with modern alternatives rather than clay.

Just wanted to make sure my solution was correct.

Thanks for your responses

Give the whole thing plenty with a big hammer, the cover will deflect and vibrate the concrete etc on the top. It will probably come free by then, if not plenty of hydraulic fluid or chainsaw oil all round the rim once concrete has been swept away.....
leave a day and as above and a decent flat head screwdriver. Once off repaint the lot with thick black gloss.. good as new

I mean the rim and lid have fused together you can’t get anything between the two

Re Buchan Trap, evil things, get rid

Yes cut it out and a straight pipe through instead

If your cover looks like this one, then should be able to break the sand/cement mix out as Rob suggested, this should then able you to remove the whole cover as they’re usually just placed on and cemented in.

Hi CBW

It’s a square cover with NO lift points. Lid and rim totally rusted and fused. Looks like it’s been covered by concrete for years.

A photo perhaps may help us to help you.

Tried getting in between the cover and the rim but it’s not working. I can try more brute force but don’t want to damage any of the brickwork on the chamber

So, circled red is your lifting point (manhole lifting key should fit) however it’s seized. Where I’ve highlighted in yellow, if you have a crowbar then try getting in there, it should give without damage to bricks.

I see one lifting point

Good spot I didn’t even notice it. Now I feel completely stupid. Thanks CBW

You would never expect to find the lifting point in the centre of the lid exactly where it’s supposed to be
