Answer

Brief Explanations:

For the first question, a missing backwater valve is more related to basement flooding prevention for the whole - house water system rather than a direct floor - drain problem. Missing drain, poor location, backing up, and no trap are all issues specific to floor drains. For the second question, clay tile piping buried in the soil is a common type of drainage piping and not a problem in itself. Missing or inaccessible cleanouts, reduced pipe sizes downstream, combustible piping in multi - family buildings, and non - standard piping materials are all common drainage piping problems.

Answer:

First question: missing backwater valve Second question: clay tile piping buried in the soil
