Today my step dad and I fixed a problem I discovered post the new pergola slab going in. Days after the area was cleared, I noticed a lot of water near the tap and thought my wife must of over watered the lawn.
Post the slab being done it was more noticeable when pergola installer cut the downpipe. i.e no water came out of the live pipes. Since these should contain water since it goes to a tank. Thought the collar (reducer from 90mm to 100mm pipe) had come off, as it had once before.
We cut out the pipe, and when we put a torch down the water was actually below the point of the collars, which meant the leak was lower.
Dug out the side to access pipe and I immediately spotted the problem. It appears the 45 degree elbow that was under the concrete slab must of been knocked during excavation of the slab area I imagine and this split it on the inside of the elbow. It was so split that it was nearly around the whole pipe diameter. It had else caused some soil to erode around it too. Every time it rained, the system would need to load up, and post rain the system would unload all that water into the rear out this split. No wonder the ground was so wet post rain.
Didn’t take and pictures of the split, as I was too covered in mud to get a camera. However did capture the picture below showing out fix, as you can see not a bad job. Loaded up the down pipes and no leaks. So win for us.
Now I can get on to the next jobs around the house and yard. So much still to do. Will continue to take pictures. Have another low spot where I am going to lay a surface drain and some arg line/pipe to help stop the area from pooling with water (where the trampoline use to be)
