    I will do those suggestions tomorrow and let you know what I find out. I also found this picture of when I was roughing in the bathroom. I left this hole open for a week or so and the water filled up much higher but this is an example of the water issue under the house. I would put a pump in it to dig and make connections and the water would fill right back up with in seconds.

    That would be a good reason to go lower and under footing, plumbers do dig thru a footing when they have to so which ever is easiest to make work.

    That's a problem (but a separate problem). Code is that foundation wall extend to 6" ABOVE grade. It helps to keep the sil plate and framing from rotting away.

    Notice that the window well as been added too before they raised the dirt level
    I would expect to see waterproofing or damp proofing to start 6 to 8" below the top of the window.
    Not sure what the lump on the left is, might have been put there for a brick ledge that was not used. I would not be surprised if the original ground level was the bottom of the window and this was some ones idea of solving a water problem.

    I will ask my neighbor if he remebers it ever being different. Here is a picture of the ledge from the inside. The other picture is of the main room that floods. I busted a small hole in the floor and water was right under it.

    The block on the inside and out side, there must be load from above that a single thickness wall would not support by itself.

    I have 3 of them along that wall. I would guess that wall is 40’ long. Above those blocks on the first floor are perpendicular walls that separate the bedrooms. None of the other basement walls have them.

    As far as the mira drain (dimple board) goes. Im guessing that is in place to not plug up the weep holes that are drilled in the blocks? Do you need to worry about radon? Do you put silicone on the wall seam or does it stay open?

    Those wall protrusions are there to help a block wall with support not from above, but for the strengh of the horizontal lenght of the wall. Sometimes inside and some on the outside help to prevent cracking longitudinally.
    Also notice the extended metal window well that goes up. This was added to raise the dirt is my 2 cents.

    Adding some drainage at the exterior is the best solution.

    Damp proofing and water proofing are not the same. Concrete and mortar are porous and moisture can transmit through it. Damp proofing will prevent this, and is required by code. But if some of the mortar joints are failing, its not going to stop water intrusion when the ground is saturated.

    It was only referred to because he is looking for the top of what ever he has when he digs outside . neither will do anything when you back fill above the bottom of the siding and framing.

    Got the sump pump installed and tied into the downspout. Seems to be working great and is taking a lot longer to fill the pit up now that the pump has been installed for 48 hours. Picked up a roll of 100’ black pipe but not sure how to feen it though the footer. The old drain tile ran through that hole in the footer.

    go up and out and back down to the bigger pipe. Usually just go thru the ledger under the floor.

    Im not sure I understand what you mean by up out and down? Is that for the sump discharge pipe? If so I got that installed just fine. As far as going through the ledger... How do I do that?

    Thanks. I got the sump pump installed and its tied into my downspout. What I cant figure out is how to get the corrugated pipe to run around the perimeter of my basement. When an interior wall meets the exterior wall how does the pipe go through the interior walls footer. In the picture that i attached it looks like they drilled through it to run the old clay tiles but the water is well below that hole. Im not sure how deep the footer goes uet because i havent ran a pump in the trench yet. Will i need to drill a new hole in the footer below the existing one?

    Have you dug out the other side of the footing, that pipe was placed there and they pour concrete around it. You can't just use that whole? Plumbers often just jack hammer a slot thru the footing .

    I have. Im usuing 4 inch Ads pipe and it wont fit through that hole. Im also thinking that the pipe needs to go a little lower where the actual water is collecting.
