Unpleasant smells in the bathroom are not unusual. But if you are smelling a bad smell in your bathroom sink, it’s something that you want to look into. Below are six common reasons why you might have a foul odor in your bathroom sink.
Clog
One of the most common reasons for a bathroom sink to smell is because there’s a clog. You want to check and see if the drainpipe has a clog in it. Skin, soap residue, hair, skin, and other things build up in your pipe’s bends. These clogs often have air pockets, and these allow the sewer gasses to come up through your drainpipe.
To find out if you have a clog, run some water into your sink and watch how quickly it goes back down at its normal speed. If it drains slowly or doesn’t drain at all, chances are that you have a clog.
Your P-trap is Dry
If you’ve checked of ra clog and there isn’t one, it’s possible that your P-trap could be dy. This is the curved drainpipe piece under your sink. The purpose of the P-trap is holding water. This creates a barrier that stops the gases from the sewer from coming back to the surface and out of the mouth of the drain. If it’s almost dry or dry, those gases can escape your drain.
Your Vent Pipes are Faulty
If you have tried the other two remedies, and you are still noticing that there’s a smell, you might have a clog, leak, or other kind of problem in the vent pipe which carries the sewer gases through your roof.
Contaminated Water Heater
If the smell that you’re noticing is coming from the hot water, replace your water heater’s anodized rod. This is what protects your water heater’s steel interior from corrosion. Any corrosive elements will attack your rod instead of your steel. But it will break down and can cause a bad odor.
Your Faucets Contain Bacteria
If you are smelling bad odors from your cold or hot water, or if you don’t need a new anodized rod, there could be bacteria in the faucet that is causing the smell.
Your Septic Tank is Full
When you have a septic tank, one of the things that you have to do is to make sure it’s cleaned out regularly. But when it becomes full, not only can it make your drains drain slowly but it also can cause odors in your drains.
These are six reasons why you might be smelling something unpleasant coming up through your bathroom sink. The good news is that they are all fixable and they are fairly simple to fix. If you aren’t sure what the problem is, or you want a professional opinion about drain cleaning, it’s a good idea to call a plumber in Manteca.
