Patio drain/heavy clay/ existing drainpipe

[momorris]

Hi all, I have a patio that was laid before we moved into the house. It slopes to the house wall and was touching the main wall below the DPC. All the water collected and sat here. I have now removed a set of flags that run along that wall and laid stone chips in its place. because of the heavy clay beneath water still gathers and sits here. I was wondering about fitting a pipe under the stones with the clay angled towards the pipe to make the water run to the pipe.

This pipe will have holes drilled and run towards my main drainpipe/downpipe from rear guttering. I want to then fit a t piece to this drainpipe where it joins the brown pipe (approx 6 inches down). do you think this would work. (the pipe would slope down to the connection).

Also discovered the mains cable to the garage breaker buried beneath the flags in the clay, standard 3 core (not armoured or in a conduit) with a connection block wrapped in insulating tape, thats another problem i now have to deal with, but at least i have found the cause of my nuisance trips.

Hi Mo

Have a look here and you will see the pipe and info you need.

First isolate the connection and get a qualified sparky. Photos please .

Thanks for the replies.

Finished the drain. I sank a pipe with holes and all is well. I dont think i actually needed the pipe anyway as when i dug out the clay i set it at an angle anyway and even without the pipe it ran to the drain and away. Still the pipes a backup that cant be seen.

seanandruby - dont worry im well below the DPC, actually at the same level of the old patio. What do you want pics of? I have sorted the cable, got some nice armoured and went overboard, put it in a conduit 12" deep and even did the tape (cable below) over the top, overkill but still its better. I changed my consumer unit myself so im happy with the sparks. It was to 16th but im still tempted to go to 17th and change my dual unit RCB to individual RCBOs.

The connection block is a mess (if you want a pic of that) clay in one corner with green terminals.

each job is different and we can only visualise what yours looks like, etc: so a picture speaks for you. No big deal really. Glad you got it sorted
