Locating main sewer connections

[Mike1958]

Though probably a vain shot in the dark could anyone provide any useful advice as to how I can get around the following problem.

 

Having recently purchased our house we will need to add at least another two WC's into a house where there are no visible foul pipes to connect into. It seems that the existing pipework may run inside internal stone walls. This in itself is not the main issue as a new stack can be created and boxed in, however the dilemma is that though we are supposedly connected to main sewers I cannot locate either rodding or inspection points or even a channel where pipework may run to the main drains in the street.

The house is the best part of a 100 years old but has had work done in that time therefore my questions are:

 

1. Can I realistically expect to find plans lodged anywhere that would show all groundwork's (drains etc)

2. Are there specialist tools or services that can locate drains without needing to dig up the grounds.

 

Any help given would be gratefully appreciated.

 

Regards,

Firstly try at your Mairie. They should have such plans.

And have you thought of using devining rods. That is how we found our neighbours underground drains. It does work.

Must admit that I had a twinge of envy too

I once had a house like that.  Loo waste pipe just disappeared into a granite wall.  We never did find out where it went!

Thanks Alexis for explaining "why we have cavity walls".

If your property is in a village or town there should be an inspection point which is roughly 30 cm in diametre and capped by a cast iron cover. Once you have found that you shopuld be able to work backwards toward the house.
