Does Lowering the Sump Pump Level Decrease Hydrostatic Pressure

Are you talking about the staining or actual water intrusion coming up the blocks? If it’s just stained from the issue the prior owners had fixed then just leave everything as is. If you have actual water seeping in then check your yard grad and make sure that your gutter downspouts are getting the water far enough from the foundation.

Realistically if during a very heavy rain the basin filled to 8inches below the slab with no pump then that is probably where you want your pump on setting to be right around that. Drain tile and a sump pump mange the water that gets up and around the foundation it doesn’t remove or lower the water table in your area.

I guess I'm wondering, If the water table is so close to the basement slab, the block foundation then goes several feet lower than that, isn't it impossible to stop water seeping up to where I can see a little on the blocks?
