Restoring A $7,000 Mansion: Building The Basement Plumbing

Cole, I've got bad news for you. You have to add a vent line to the floor drain at +14:00 . The 2-inch drain line going back to the drain for the boiler is too long for it to serve as a wet vent for the floor drain. And the main stack is too far away and on a different branch. You've got a similar problem with the second floor drain. For the first floor drain, I suggest you insert a 4x2 wye (tilted on it's side) just past the floor drain. Then run the 1.5-inch vent line back towards the wall where the boiler drain is going to be and run the vent up that wall and tie it together with the vent for the boiler p-trap and drain line. NOTE: A wye used to connect a vent to a drain line can NOT be laid flat, it must be tilted. Dry vent lines do not have to be sloped, they just can't enter the drain line horizontally, the wye must be tilted upward. The minimum pipe size for a dry vent is 1.5-inch, that might be small enough to keep most of it below the bottom of the slab.

You need to install a back flow preventer valve to prevent water from outside your house flowing into your basement

Roman is a very intelligent and one hard working individual. My respect to you Roman.

I would suggest hiring a licensed plumber to come inspect your work. That way, you can verify everything is to code and will work correctly before pouring the basement floor.

I said it before and I’ll say it again, Roman is a Beast

I love how you give Roman credit for his work, his ideas and his ethic.

Hey I'm a plumber in New York City. Quarter inch is for storm systems that don't move solids eighth of an inch is for sanitary that moves fecal matter. If the pitch is too great The fecal matter will sit in the pipe 1/8 of an inch allows water and fecal material to move at the same rate

Need to add vents for any fixture. Floor drains and WC. Also I would get an actual plumbing inspection by local authority.

Roman has a great personality, and a sense of humor.

Please have a licensed plumber show you where you need to add vents. ALL devices need to be vented or they will not drain properly. Assuming a single 4" wet vent will do it is pure folly. You need vents!

I hope you need to have the plumbimg inspected just so your family is safe. Your family is amazing and I want to keep it that way.

All those tasks to do, makes my head spin... It seems Roman is a miracle man...plumbing, building, designing and of course Arm Wrestling Champion.

When you’re all done, take pictures, print pictures and keep in binder in case you need to dig up.

I'm not a plumber, but I wouldn't want floor drains tied to the septic for multiple reasons. If you ever need those drains, you might overload your septic. We always daylighted the drains and a pipe in the sump if possible.

I re did all the plumbing in my house including everything underground just like you are doing. I studied the code book as well as alot of internet research. Some issues i notice you are missing a lot of venting remember air after water. All those floor drains need trap primers since the are tied into the sewer/septic to prevent gases when the traps dry out. Also you really need a back water valve.

Who works harder than Roman? Absolutely no one! Love that guy!

It would be great if more people worked like Roman. He bust butt to get things done. You got a great friend there.

Hello! Actual contractor here. My advice to you is that I’ve never EVER seen a homeowner job that was done correctly. Ever. Hire smart people. You’ll never regret it.

It's a brave start! I would have started up stairs and make all the home runs and brought it all to the basement. Also on your drains for the boiler drains install a P trap to prevent sewer smells. Where are your vent pipes? Floor drains connected to sewage system not good. Problem is you need to keep water in P trap drains other wise sewage smells will vent into house. Please don't pour concrete until you fix these problems.

After watching you work on your house and the farm all these years I didn't think there would ever be someone who worked as hard as you do. Roman is that guy ! 👍
