    When I open the post, the heading is there but no content.
    And while in there, the content section keeps jumping.

    There is content when I go into the op's profile section, but it won't show all.
    ??
    edit..and renovate forum at the very top left of page keeps changing to french drain with hump, as if it is trying to open the page but is being stopped by something.

    edit 2.. in the last 8 minutes, it has stopped jumping and I can type in the content section, but still no content from the op.

    edit 3.. it is jumping again.

    edit 4.. The content is in the op profile section but when I click on read more, I am sent to the post which is still jumping, and shows no content.

    I read the whole post last night - it went into quite some detail. It's gotta be there somewhere!

    The post had a duplicate which was deleted sometime after the other one was approved. Maybe something to do with it!

    This is the content:
    "The folk who laid the original french drain did not lay it very evenly and the flexible drainage pipe has a hump in the middle section. The length of draining pipe upstream of the hump is permanently full of water even though it still works.

    i.e. The pipe is clear and not blocked and water will drain from the entire length of the pipe but due to the hump one section is full of water all the time.

    The earth is thick clay and water impermeable.

    The retaining wall is the foundation for the back of a house built on a slope. The house is 8 years old and the hump has always been there and there has been no subsidence.

    There is a strip of grass 2m wide to the rear of the retaining wall. The earth on the downslope side of the retaining wall is only 6 inches below the earth to the rear. The retaining wall is set 1m deep into the ground and mostly buried.

    The drain is 2m back from the retaining wall so as to stop the 2m strip of grass behind the wall from getting boggy. The french drain pipe is only 15cm below ground. The water the drain collects runs off a 7m slope to the rear of the 2m flat section behind the retaining wall.

    I have discovered all this information by digging the top layer of earth off the french drain. It was clay earth and completely impermeable so the french drain was not doing anything. Water was running over the clay cover and then along the back of the retaining wall and draining round the side.

    Now I have removed the clay topsoil and uncovered the gravel the drain is working again. It works for its full length as even the part of the pipe that is under water still acts as a conduit from water pressure.

    I was going to replace the clay top soil with gravel so the french drain channel is gravel all the way to the surface.

    Is it OK to have gravel all the way to the surface in a French drain instead of the usual top layer of top soil? The soil here is cvlay and no good as a french drain cover as it is not permeable at all.

    Rather than dig up the submerged length of pipe that is too low (upstream of the hump) I was thinking of 2 solutions

    1. just fill with gravel - the submerged section of pipe still works as a water conduit even though it never empties. although flow is slower from this section

    2. add a parallel second section of draining pipe just above the submerged section. should speed up drainage from that section even though there will still be a 2nd section of submerged pipe also acting a conduit (with slower flow) beneath the new section/

    Would there be any problems with there being a submerged section in the french drain which never empties but always has a hidden subterranean pool of water in it?"
    Not sure what is going on!

    For those computer problems:
    Reboot your computer. During the time it takes to do so, take a pinch of salt and throw it over your left shoulder as you turn seven times, one time in each direction and mumble: ... umpa bumpa comme poste ... repeat 7 times.

    For those drainage problems.
    Dig up the drain, dig a proper trench, deeper and with a constant fall, lay the pipe, fill with gravel and watch the grass grow ... or whatever you do when you finish a job and feel satisfied.

    The thread had a duplicate posting and somehow deleting the second has removed content in the first one though I can see it but others can't. I did not do the initial approval and hopefully it gets sorted out. Just need updates if it suddenly comes to life as I say, the content will always appear for me.

    Can you undelete the second one to see if that one works?

    Thanks Bedford. I changed the heading back to what it was so hopefully nothing has changed from doing that.

    You can have the rest of the day off now!
