Please help.
I am buying a new house (old foundation but newly renovated) but have second thoughts now that I witnessed sewer overflowing onto the basement floor from the house trap. Here are some facts about the house:
Located in Queens, NY near a swampy area and is close enough to another area which is known for flooding.
House trap is about one foot deep in a basement cut-out.
No automatic check value is on the property.
One plug was missing from the house trap and one was there following cleanup of the sewage that spilled onto the basement floor.
Questions:
1. Even if the missing plug led to the sewer spillage, if both plugs were there and secure is there a possibility in the future that a backup could emerge from else where (like the toilet, sinks, etc?) when there is pressure?
2. Just to be safe, should I have the current owner install a automatic check value on the property in addition to putting in brass clean out plugs?
3. What if regular maintenance of the house trap is needed? Would a brass cleanout plug or a lead fitall be appropriate?

>Yes, if the house trap plugs were water tight, the waste water would travel inside the drain system and overflow or spill from the lowest level fixture or overflow from the house trap vent, it may even just fill up the piping depending on how the drain pipes, vents lines and fixtures are laid out.
2. Just to be safe, should I have the current owner install a automatic check value on the property in addition to putting in brass clean out plugs?
>Unless, the waste water/sewage was backing in from the city main in the street, you should not need a back water valve, they have thier own problems.
3. What if regular maintenance of the house trap is needed? Would a brass cleanout plug or a lead fitall be appropriate?
>Mainly, you’ll find lead fit-all plugs in the house trap, unless the trap is fairly new and brass plug threads will mate with the threads of the house trap clean-out threads.
What exactly caused the stoppage and what was done to correct it?
