No, it is one pipe going to the street. Just because you see no water
at the curb doesn't mean the system isn't full. The backup is occurring
much lower in the main. If it is slow days after an event, yes, you
might have pipe or root problems.
You should be able to find the pipe that goes into the basement from the
upstairs. All the different areas, kitchen, baths, laundry, will work
their way toward the "main" in your house. The floor drains all tie
into this same main before leaving your house. The main can either be
at the wall going directly to the street, or it can come out the side.
Usually, they were on the street side as it is easiest to connect to the
city. Once you find your main, it all starts making sense.
Your floor drains might have a build up of crud in them, but usually
won't have a lot of roots, because they are only under your house. What
a plumber will look for is the "tee". This is usually right against the
wall somewhere, and is the last place you can access the pipe before it
leaves your house. This is where he would clean, rod, and video the
line going to the street. This is where you will get root buildup.
This is where most pipe breaks happen. These types of issues cause
problems with getting the water out of your house into the city's
system. They are not the cause of water coming back in during storm events.
When these events happen, you will get the backup in your sewer system
almost predictably, until somewhere down the line from you the system
gets a greater capacity. So what do you do? You cannot plug the floor
drains, as this has a very good probability of breaking a pipe. It is
hard to explain the amount of pressure created when sewer systems back
up, but I think I've told the story of when I watched a utility pole get
launched out of the ground that had partially blocked a service to a
house.
If it were my house would I try a standpipe? Probably not, and for the
same reasons. Yes, you will raise the level and possibly keep yourself
dry. However, the pressure on the pipe system coming into and under
your house increases exponentially for every inch you raise the water
escape level. It could burst right at the worst possible spot on your
foundation. Is it worth the risk. Perhaps.
I would elevate the system, and probably line the pipe to the street at
the same time. It would be expensive, but to me worth it. Get an
estimate, you might be surprised. If you could only use PVC, but that's
another story.
Most likely, everything upstairs comes to one location before going
downstairs. This is the pipe going into the basement that goes out to
the street. This is the area you will have to place an ejector pit to
send up anything you have down there like floor drains, laundry, or bath
sewage. Usually everything under the basement floor also comes to this
final area, minimizing how much floor you have to break up. This gets
pumped up to the new pipe going out your walls with everything connected
at the higher elevation. This is where the plumber digs his hole
outside the house to make the new connection and abandon the lower pipe.
Get a couple estimates to find out exactly what you have and compare.
You should be able to get some companies to do free estimates. If they
don't, I wouldn't use them.
All of this has nothing to do with water coming in from other sources
that would be handled by a sump pump like leaky walls, or cracks in your
floors. That is an entirely different situation. This is only for sewage.
