### Additional Information:
**Types of Drain Assemblies**
There are several different types of drain assemblies available, including:
– Basket strainers: These strainers have a removable basket that catches food and debris.
– Pop-up strainers: These strainers have a stopper that can be opened and closed to allow water to drain or to fill the sink.
– Garbage disposals: These devices grind up food waste and send it down the drain.
**Materials Used in Drain Assemblies**
Drain assemblies are typically made from the following materials:
– Stainless steel: This material is durable and rust-resistant.
– Brass: This material is also durable and rust-resistant, but it is more expensive than stainless steel.
– Plastic: This material is less durable than stainless steel or brass, but it is also less expensive.
**Troubleshooting Common Drain Problems**
– Slow drainage: This can be caused by a clogged drain, a faulty drain assembly, or a blockage in the main drain line.
– Leaking drain: This can be caused by a loose drain assembly, a damaged drain line, or a faulty seal around the drain assembly.
– Clogged drain: This can be caused by a buildup of food waste, hair, or other debris.
