What is a potential risk when using improper fittings in drainage systems?

Using improper fittings in drainage systems primarily risks causing leaks and blockages. Drainage systems are designed to facilitate the smooth flow of wastewater and stormwater. When fittings do not match the necessary specifications or are not suited for the particular application, they can create weak points in the system.

Leaks may occur at the junctions of these unsuitable fittings, leading to water escaping where it should not. This not only poses a risk of water damage to surrounding structures but can also lead to unsanitary conditions if wastewater is involved.

Blockages can also arise due to improper fittings causing irregular flow paths, traps, or bottlenecks in the drainage line. These blockages can lead to backups, which can be inconvenient and harmful, increasing the potential for overflows and additional damage.

Overall, the integrity and efficiency of a drainage system are critically dependent on the correct selection and installation of fittings.
