moving a drain inspection chamber
16 Answers
Does anyone know roughly how much it would cost to move a drain inspection chamber. It needs to be moved about a metre and is about 1.5 metres deep, there is only one branch going into it so far as I can see. We are having an extension and wish to instal a shower and the inspection chamber would be partly underneath the shower enclosure if it stays where it is. There will be a continuation of the house floor which is joists and floorboards on top of it but I can't see how it would be possible to lift the lid if it is partly underneath a shower, even though it will be about 20cm below the floor level. We are located in the north of england

You don't have to have it there at all .. but it is probably for cleaning/access etc.
Personally I would not have any chamber inside unless absolutely necessary, but you may be able to change for a small sealed-access plate. You can buy these.
Check where everything runs so you can make the decision.
Removing/replacing could take up to a day at local builders rates.

it has to be inside, no choice unfortunately. There is a straight run of drain into it from the soil stack which serves the bathroom. This is all that runs into it so far as I can see, there is a separate drain which takes water from sinks and taps. The inspection chamber has about 20cm of concrete around it but beneath that is just regular ground.
the stack is also going to be inside the extension so to avoid overlaying the inspection chamber cover with the shower it would have to be moved. the extension will be quite long and narrowish and to make it look reasonable, and because of where the window will be, the shower enclosure can only be in the corner where the inspection chamber impinges

Pleased to know it may not be a massive job. Best I can describe for a plan is the extended room is 3.8m long x 1.5 wide. standing in with back to the orginal part of the house, the window is on the end wall on the left and the door entering it is on the end wall on the right. I want to have the shower in the right hand corner next to the door but the drain cover is about 30cm from the original wall so part of it would be underneath the shower enclosure. The soil stack is immediately adjacent to the inspection chamber cover and is attached to the original outside of the wall. The drain from the soil stack runs straight into the main drain which then runs along the driveway to the front of the house, where it joins up with the drains from other houses and where there is another inspection chamber which will not be a problem as it is quite a distance from the house.
OK. As Trim has said, it shouldn't be a big deal. The rule is that inspection/access chambers should be anywhere where the drain bends and changes direction............ so,
1 either re-locate the stck and drain run to outside of the extension.... or
2 seal off the existing chamber and introduce a new one somewhere else in the line. Preferably outside the building, but, if that's not on, then put one further along the line away from the hower. It'll still be in the extension, but that's ok with a sealed cover. It must be accessible though....... so take that into account when deciding on flooring.
As for cost......... not a great deal if its done by the digger (JCB) when he's excavating the new foundation tranches.

Thanks for the answers - maybe its not quite as complicated as I thought it was going to be, and in the great scheme of things (a pretty expensive kitchen extension plus bathroom utility), the cost might not too big an issue, especially as mentioned it can all be done at the same time as the foundations are being dug. Can't wait to get started (planning department considered) but that might well be another issue altogether
Good luck ................. you might not need Planning Consent ........ check out the Ineractive House on The Planning Portal
