How to Unclog and Replace a Drain TrapEvery homeowner has experienced such a plumbing issue as a clogged drain at one time or another. Sometimes, the fix might be as simple as plugging the drain. However, other times, you may need to clean or replace the drain trap.

In some cases, the issue may be more serious and drain repair by a professional plumber may be required. In this article, we shall provide advice on how to clean or replace the drain tap in your bathroom or kitchen sink.

What Is a Drain Trap?

The drain trap is located beneath the sink or bathroom drain pipe. It allows the drainage system to function properly. Also, the curved section of the p-trap, as it is also called, maintains a water plug to seal the house drain pipe against harmful sewer gases. 

It is imperative that every drain trap in your home is in proper working order. If you notice that the drainage flow is slower than usual or has stopped, there could be an issue. You should regularly inspect your drain trap for any damage or malfunction. 

P-traps are either composed of PVC pipe or steel. However, they may also be made of a variety of other materials. Some of these may be prohibited by building or provincial codes, so it is best to ensure that you are only using the correct P-trap for the area in which you reside. You should be able to purchase a P-trap at a local DIY, hardware, or plumbing supply store.
