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 TH-cam and did all my home reno from Chimney to the floor.

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.
Every plumbing fixture in your house has a p-trap that holds water in the pipe. The p-trap is designed to prevent sewage odors, insects and rodents from entering the house through the sewage system. The main concern would be your toilets which hold a significant amount of sitting water in the toilet and the p-trap built into the toilet.
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.
See "How to Install a Flood Control System | This Old House" on TH-cam. 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.

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

That wasn't a plumber, that was a fake dumbass!
TH-cam channel recommendations?

What is the reason for gravel? Could I substitute dirt? Thanks
Would this stop mice getting in through sewer?
This is a good question, hope some one answered

That’s a cool device but that’s just one drain. How do protect against toilets and showers in the basement from backing up?
The device is installed BEFORE all other fixtures. Making them all protected. It is designed to protect basements from the city sewer side.
What is the purpose of the pvc pipe going above ground?..
Clean out

How much does it cost?
that check valve is a toy. stronger flood will rip it apart. get a real cast iron check valve.
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
