If your drain directly flushes your waste down into your sewer line, why don’t you normally smell sewage? Well, you have your sink’s P-trap to thank for that!

What Is a P-Trap?

-Appetite loss
-Memory issues
-Sinus infections

You’ll likely notice the smell of rotten eggs coming from your sink, meaning these gases are making their way past your P-trap and into your home.

Preventing Clogs
The U-shape of its piping makes it so your P-trap will likely clog first before your drain line. It’ll normally catch the debris, allowing you to toss the waste elsewhere by removing the trap and clearing it out by hand – much more manageable than your typical drain line clog.

Protecting Your Valuables
It’s pretty common to lose small jewelry like your ring or earrings down your drain. You may have thought your valuables to be forever flushed through your local sewer system, never to be seen again, but it’s likely been sitting at the bottom of your U-bend all along. Taking the time to remove your trap and clear it out is plenty cheaper than buying new jewelry.

Issues You Might Face


Insufficient Ventilation
If your drain line doesn’t have proper ventilation, the air suction pushing and pulling throughout your lines as you drain your wastewater will empty the water in other P-traps besides the one you are using at that moment, leaving your home potentially vulnerable to sewer gases in multiple drains at the same time.
P-Trap Cleanout

There are a few homemade drain cleaning remedies you can use on a regular basis to keep your U-bend in good shape and less likely to cause you problems.

Make room under your sink, clearing and relocating anything that might get in your way.
Place a bucket under your piping to catch any dripping or spillage.
Loosen the two coupling nuts connecting your trap to the drain and overflow pipes, and set them aside.
Clean out the inside of your trap with a wire brush.
Reassemble your p-trap, make sure that your washers are set properly, and the coupling nuts are re-tightened.
Finally, run your water for at least 30 seconds to ensure there’s no leakage.

P-Trap Installation
There are two general rules to installing a P-trap you should consider, especially in states like California which have codes that involve restrictions for using this kind of a trap.

Don’t install more than 3 appliances all on one P-trap or you’ll overload it.

Any P-trap that won’t be frequently used should have a trap primer attached to it. It’ll keep your seal and prevent sewer gases from passing through and easily entering into your home. This is also a good consideration for those extra dry climates which will quickly evaporate the water in your trap.
