hi dimp, ok let me get this straight. first, you have a cinder block bsmt wall, yes or no? Not brick but cinder-block-there is a difference.
From the inside of basement you see water up-high which then runs down the wall onto the floor, right?
You said this problem-area is by--at the front entrance, so what i need to know is...is the front entrance a Porch or, maybe just a concrete step or 2? Or, is your front entrance level with the ground and there is no porch and no steps???
Sounds like this front entrance is at ground level SO if it is then when the builder or whoever runs the water...then there is a direct opening(s) into the house NEAR--at where he is running the water and needs to be correctly sealed on the outside with either cement/tar etc, depends what and where this opening(s) is. If you have a Brick on the outside of yer home, it sits on top on the basement wall, so he/you need to dig that area DOWN a lil bit with a digging shovel to view that area, probably dig it down about 6-12" and scrape and wire brush the 1st course of bricks and exposed top part of basement wall.
If the ground/soil is built UP Against the Bricks your probably going to find openings between in the moratr joints between the bricks and-or a craked/loose brick or 2. And again, you may also have openings along the brick ledge, where the first course of bricks sit on the bsmt wall and they all need to be sealed/fixed correctly. Know what i mean?
Thats how `n why water is entering when the hose is run at ground level, because there are going to be direct openings right at or just below where the water is being run.
The builder unfortunately simply doesnt know-understand, no biggie. They hopefully & probably are much better at putting the home together, expect for leaving outside openinhgs where water can enter.
Again, the hose test is Very valid,no need to wait for a rain,lol. The water test is showing you--him there is a problem-opening(s) Period! Find the openings, seal `em correctly, i cant be redundant enough.
