# How to Make a Standpipe in a Basement
One of the most important things you can do to help prevent basement flooding is install a standpipe in all the basement floor drains. Standpipes usually are installed 2 to 3 feet above the basement floor level. This allows any backflowing water to rise up into the pipe rather than onto the basement floor. You can make a standpipe for your basement with the proper tools, materials and do-it-yourself ability.

- Flathead screwdriver
- Phillips screwdriver
- Expandable drain gasket
