So this method on video is wrong or not advised?

@@keshavr9617it is not “wrong”, but it is not waterproofing. It is water control. Like they said sometimes it is not possible,or practical to dig up the exterior to waterproof the basement properly. The problem with this method is , because you allow the water in then redirect it back out the basement can seem “ damp and musty”. You can use dehumidifiers to try to help mitigate it. But that is not always successful.But interior drainage systems will stop the basement from actually having standing water in it. A better solution, if it can’t be properly waterproofed from the exterior, is to use crystalline waterproofing from the interior. It penetrates the walls and makes the wall itself waterproof. But this method requires access to a clean interior masonry wall. Again sometimes not possible or practical. NEVER PUT A WATERPROOF COATING ON AN INTERIOR MASONRY WALL TO STOP WATER INFILTRATION. It will cause the wall to deteriorate.

What do you suggest doing for a wall with no footing? There's not much information about this. I plan on still digging a trench, but over a foot away from the wall. Let me know what you think. Thanks!

@@paulzapol9840 I’m not sure exactly what you mean. Is the wall sitting on top of the slab?

@genecarden780 No, it's a slab butted up against a wall like normal, but no footing under the wall. I want to dig a trench like normal, but without the footing, I'm afraid I will compromise the wall. I'm thinking of moving the trench about 16" from the wall to leave a good section of the clay dirt to act as a footing. I'm just wondering if that would work.

no its gay

Inspector should make alit less than these guys.

This is a good question, hope some one answered

that check valve (backwater valve) is fine and will protect you in case of a flood, not really sure why you're suggesting a cast iron

See "How to Install a Flood Control System | This Old House" on KZbin. The lady had 40 inches of sewer water that backed up into her basement. That amount of water pressure from that amount of backed up, overloaded sewer blew her plastic backflow valve apart. The pressure was just too much for plastic. They replaced it with cast iron. Plastic, PVC, would probably work just fine at lesser pressures. Just not quite sure what that load would be.

Clean out

If you use a snake from a location upstream of the backwater valve then it will work fine PUSHING , but when it comes time to PULL the snake end will catch on the flap and become a problem. So u put a cleanout on the downstream side of the backwater valve and only use that as the clean out downstream. And if you pull a toilet above the BW valve to snake the pipe then you have to remember not to continue snaking BEYOND the BW valve or else someone has to open the cap and hold the flap from getting caught. Not a bad idea to label each toilet flange with some indication that a BW valve is downstream. You can try to use the BW valve as the cleanout but a flexible snake will not cooperate with a sharp turn and you'll fight it while the cleanout is a wye fitting with a 1/4 bend that helps the snake stay horizontal and not buckle.

That sounds like the worst plumber in the world. He must be from Two Dogs Plumbing.

@@jamesduff6937 His dad wrote a contract with me and conned me out for not getting the city permit then his son did the job. Found out the guy lost his job at the oil company, came home to work with his dad and never been to trade school as plumber. Since then I always asked contractors to get city permit before the job.

That wasn't a plumber, that was a fake dumbass!

KZbin channel recommendations?
