How Direct Waterproofing approaches installing a backflow valve in a wet basement situation:
1. The first step in the installation process is locating the main drain line exiting the house. Once the line is located the Direct Waterproofing team will carefully excavate the concrete around it and clear up the drain pipe.
2. The second step is to cut out the section of old clay pipe.
3. The third step is placing the Backwater Valve in front the drain pipe.
4. The fourth step is cutting and gluing the PVC pipes and connecting them to the Backwater Valve and the old clay pipe and checking levels, as it is important to keep the original flow, so that the water flows out of the house and into the city drain.
5. Next we connect the Clina and extend upwards so it reaches up above the top of the floor.
6. Once the level is established, the space around the Backwater Valve is filled and compacted with gravel.
7. After the plastic box shield (the access box) is installed over the Valve. Which makes for easy access whenever the Valve needs to be cleaned.
8. Once the access box is installed the space around is filled with gravel.
9. The last step is pouring concrete and levelling it with the basement floor.
10. At the end, a Direct Waterproofing manager will came out and check the job site and make sure that the job is done right and the place is clean.

My plumber was cheapy, he was not using glue on PVC pipe, I asked him why he didn't glue the pipe connection joints, he said don't worry, the gravity flow will take care of it and glue is expensive ($3.99 at homedepot) I told him, I will do the cement cover because I wanted to be sure no leaking before sealing it up. Well, every time I flushed water upstairs, the water sipped out at these un-glued pipe joints, the underground soil was constantly wet and developed smell after three days (mold). A week later, I called them and they had to redo it this time with glue but still cheap out by gluing only half the circle of the pipe. That was my first time ever calling in a plumber. Since then I watched KZbin and did all my home reno from Chimney to the floor.

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.

What is the purpose of the pvc pipe going above ground?..

Clean out

[@OggyBleacher]

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.

[@rudolfoization]

that check valve is a toy. stronger flood will rip it apart. get a real cast iron check valve.

[@ImperialEwok]

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

[@tompem]

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.
