someone coming, first trying to access from basement for both sewer drain and weeping tile drain but did not find that (now I found out they are under the closet carpet). I only have a not big limit on water damage coverage. I like to see some less costly solution than replacing all weeping tiles around the houses, if possible. It is a rental house. so they dug two 8 feet holes, one in back of house and one at front, you see the photos. They told me both holes are filled with water. I asked them to put snake camera in, which they suppose to do. They told me no need to put snake camera in because it will see nothing, just black. Now you told me the building shall be built with gravels over weeping tiles, I looked at the photo where hole is, I am not sure there are all gravels (but do see some gravels). The holes are immediately filled, and I have no time to take any further photos. Jy, so you think the weeping tiles are clogged by the soil or here it is called iron-eating bacteria all above the perforated weeping holes so no ground water can get into the weeping tiles and be drained? In this case, I have to change all weeping tiles. i think the perforated weeping tiles itself may not much clogged. Jy, do you think if I can go a cheaper way, install a sump pump with (a water collection place a few feet below the basement floor) will solve the problem, I can just collect the ground/surface water and pump out constantly into the weeping tiles? Jy, what puzzle me, on the first photo I posted, how do I tell which pvc drain is weeping tiles, which is sewer drain? I saw the white pvc drain at left bottom of the first photo has "sewer" words on it. So maybe the white pvc drain that I managed to open is a french drain, not the sewer drain you think, and maybe I can do some temp ways to drain the surface water into this drain with the cap open??
