Laying New Patio

[charliefunkuk]

I am about to lay a new Patio at the rear of my house. The way the land lies and indeed the way its already been dug it would be much easier for me to slope the Patio towards the house rather than conventionally away and place the Acco drains along the boundary of the house. Can you please tell me if this is acceptable practice? The acco drains will be linked into the existing rainwater system that runs around the house.

Look forward to hearing from you all.

There are no rules for drainage, other than the water should be carried away to prevent either surface ponding (and winter ice), and no localised soggy ground.

So which way it slopes does not matter.

What does matter is that drains connected to the sewer are trapped to stop smells coming up

Edit:
Should be drain not sewer, ie what is there already

didnt even know you could coonect rain water into sewer drains? Anyway the Accos would connect straight into the rainwater drainage system that exits heaven knows where, I just connected it to the original system that was there from the original building that was altered a bit to accomodate the extension. I am sure the pipes head off somewhere to a soak away.

Well technically you do need an Aco or similar if the ground level externally is to be raised up to dpc level especially if the slope is going towards the building (which is not good practice either incidently)

Technically you can only drain rainwater into a mains sewer if draining into a soakaway or watercourse is impractical.
