It probably seems like an odd name, and most people may have heard it but may not know what it is. A P-trap is part of the plumbing system that allows water to drain from a sink.
Primarily, it prevents sewer gases from coming back up the pipe and foreign objects from going down the pipe. It’s comprised of two 90-degree joints that resemble the letter P.
Since a P-trap is designed to prevent foreign objects from going down the drain, sometimes it can get clogged. Sometimes, it’s a DIY project, but sometimes you’ll need one of a plumber to clear the clog.
Quick Takeaways
- Yes, a P-trap can get clogged due to debris, lack of maintenance, or age.
- Since P-traps are designed to catch foreign substances that would otherwise go down the drain, they are prone to getting clogged.
- Food particles, grease, hair, and soap scum are common causes of P-trap clogs.
- When regularly maintained, P-trap clogs can be prevented for the most part. However, if a drain isn’t properly maintained, you may need a plumber to clear the clog.
- To keep your drain and P-trap clear and reduce or eliminate clogs, schedule regular maintenance with one of our punctual plumbers.
What’s a P-Trap and What Does It Do?
The shape of the P-trap creates a barrier that inhibits the upward passage of sewer gases between the pipe and your living area. It’s sometimes called a preventer trap or an intake trap. There’s usually a small amount of water in it due to the shape of the pipe.
Some of the gases that are blocked by a P-trap include:
- Ammonia
- Hydrogen sulfide
- Methane
- Nitrogen oxide
- Sulfur dioxide
Sometimes, a P-trap can function as a loss-prevention device, such as when you drop a ring, earring, or other piece of jewelry down the drain. A P-trap keeps it under the sink rather than sending it into the sewer.
It’s called a P-trap because when laid on its side, it resembles the letter P.
Do P-Traps Get Clogged?
Absolutely! Just as with any other drain, a P-trap can become clogged for several reasons. Since the P-trap is designed to trap debris and foreign objects, it can easily become clogged.
Why Do P-Traps Get Easily Clogged?
Some of the most common culprits that clog your P-trap are as follows.
Hair and Soap Buildup
Soap buildup can occur in bathroom or kitchen sinks. Hair clogs are more common in bathroom sinks, but can also occur in kitchen sinks. Many people use their sinks as an adjunct to the trash, both in the kitchen and the bath, and this causes lots of P-trap clogs.
Your sink should be used for its intended purpose – whether in the kitchen or the bath – and that purpose is to drain water and liquids down to the sewer pipes. When you add other items, you’re asking for a clog, either now or in the future.
Grease and Food Debris
This primarily pertains to the kitchen sink, but can also occur in the bathroom. Anytime you have grease to dispose of, you should put it in a container and then into the garbage can.
Even oil gets sluggish when it’s cold, so don’t put butter, shortening, lard, margarine, or oil of any kind down the drain unless you want a visit from one of our punctual plumbers.
Mineral Scale from Hard Water
Hard water buildup can also cause blockage in a P-trap, and for this type of clog, you’ll probably need a professional to clear it. Many areas of the country, such as Florida, have hard water.
This means there’s an abundance of minerals in the water, which can cause problems with pipes and appliances.
Foreign Objects
Even with a strainer in your kitchen sink, very small objects can still slip through and cause a clog. This sometimes occurs in the bath also, but less frequently than in the kitchen.
Signs Your P-Trap Is Clogged
If you notice any of the following:
- Gurgling sounds in your drain
- Constant small clogs
- Foul odors
- Slow draining
- Standing water
Then you may have a clogged P-trap, or one that will be fully clogged before long.
Can You Fix a Clogged P-Trap Yourself?
That depends. In some circumstances, you can DIY a clogged P-trap. At other times, you’ll need professional help from one of our punctual plumbers. It’s a messy job, though, either way, so if you’re doing a DIY project, have the following ready before you start:
- Bucket
- Flashlight
- Plumbing wrench or large adjustable pliers
- Rags
- Rubber gloves
- Safety goggles
How do you know when it’s a DIY project? If you can’t easily clear the clog by removing the P-trap, then it’s no longer a DIY project.
At this point, reconnect the P-trap and call a professional. Although it may sound unnecessary, it’s important to wear safety goggles when you work so that no contaminated water gets into your eyes.
When a P-Trap Clog Means You Need Drain Cleaning
If your P-trap keeps clogging, then you may have an underlying problem. Sometimes, it means that there’s sludge beyond the trap, and the sludge needs to be removed to prevent future clogs.
Sometimes, repeated P-trap clogs indicate that multiple fixtures are involved, and they all need to be cleared. Sometimes, it’s a combination of problems that need to be addressed to ensure that your drains remain free-flowing.
How Does Professional Drain Cleaning Prevent P-Trap Clogs?
Your professional plumber has equipment and expertise that enable them to reach areas that you can’t reach with typical homeowner tools. They can remove sludge and buildup inside your pipes and restore the full pipe diameter. When your pipes are clear, you’re less likely to have a clogged P-trap.
Although regular professional maintenance can keep your plumbing clear and free-flowing, regular DIY maintenance can reduce the number of incidental calls that you need.
FAQ
How frequently do P-traps get clogged?
There’s no schedule for clogging in a P-trap. Usually, P-traps in high-usage areas will clog faster because of the increased likelihood of something going down the drain.
However, if you notice unpleasant odors, gurgling, or slow drainage in your sink, your P-trap may need to be cleaned.
Can a clogged P-trap cause sewer gas smells?
Yes, this is one indicator that your P-trap needs to be cleaned.
Is a clogged P-trap dangerous?
Yes, a clogged P-trap can expose you and your loved ones to dangerous sewer gases that can cause fatigue, headache, nausea, and respiratory difficulties.
Should I use chemical drain cleaners on a P-trap?
You should avoid chemical drain cleaners when unclogging a P-trap. The chemicals can damage plastic pipes and soften the rubber washers.
They can also damage finishes and make the clog more difficult to remove. Natural methods are preferred over chemical methods, but otherwise, you should call one of our punctual plumbers to clear your clog.
How do I know if the clog is past the P-trap?
There are several indicators that your clog may be past the P-trap, such as:
- If you’ve cleaned the P-trap and the clog persists, then it’s past the P-trap
- If you can’t reach it with a snake, then you need a professional plumber
- If other fixtures start having water back up into them, then the clog is past the P-trap
