Odor from Decolav bottle trap

I had a Decolav bottle trap installed in a frequently used bathroom sink almost 2 years ago with no problems. About 2 months ago I noticed a sewer gas odor occasionally. Stack (inside and out) checked OK. Is there anything about the Decolav that I should know about?

There really should be a trap with a bend in it on the system at somepoint to prevent odour ingress?

Bathroom sink smells strongly like sewer when water runs fast.


Suppose you plugged the drain of the sink and filled the basin with water, then removed the plug. I must think that only after the basin empties you would get the sewer smell, and the smell would persist until you slowly ran some more water. If you try this, and this is the result, then the problem is that the sewer vent (that is supposed to prevent the water in the trap under the sink from being sucked down the drain) is not working right. If this is a new problem then you may be able to clear what is probably a blocked vent pipe. If this bathroom has always had this problem, then you have a poorly designed or executed vent pipe setup that you can only fix it with some surgery to your plumbing. However, to clean the vent you can try pouring a good bit of drain cleaner down the vent pipe on the roof, followed by water. But because there may be several vent pipes sharing the same vent stack out the roof, the drain cleaner may not get to your blockage and may simply go down a different path. Good luck.

Sewer gas smell in bathroom.


Sounds like you have an intermittently blocked vent pipe (the one that goes out through your roof). If there is gas pressure in the downstream sewer line and it can't get up through the vent, it could bubble up through your toilet or sinks. I would get up on the roof with a few jugs of powerful drain cleaner and dump them into your vents. You might also run a few dozen gallons of water down those vents after the drain cleaner has had time to work.
Good luck!

I am attempting to install a new Danco P-Trap beneath one of my bathroom sinks. My frustrating problem is I am unable to screw the pvc drain pipe to the U joint. The gasket that comes with the kit makes it...


Assemble the hardest part first, but don't tighten it up. Connect the other parts, but don't tighten. Go back to your hardest piece and tighten. Then tighten the remainder.
Best regards, W/D

Can't remove metal drain assembly for moen bathroom faucet. The metal lip that is on the sink.


you must have a pair of stillsons or a wrench that can handle round pipe . under the sink you have the s/p trap . remove trap with two wrenches because you turn them in opposite direction to get full control . once you remove the trap wich is self explained . the plug and waste wich you are having the problem with is stuck in ther with putty or silicone or any thing like that so now you have access to the bottom of the waste you put your wrench on the waste plug and turn it any way you can left or right you want to break the water seal without breaking your sink the water seal [the silicone or putty ] is really tuff so you have to use full strength without breaking the sink like i said . the older the harder to get out . im a plumber and have had plenty of tuff ones but they allways give without cracking the sink so go hard but be careful as well

How do you clean a bathroom sink drain with a cable operator?


You will need to remove the cable operator assembly first. Under the sink, unscrew (turn it counterclockwise) the operator with your hand. Then remove the butterly-shaped retainer and use a needle nose pliers to remove the cam assembly...don't get too rough. Pay attention to which way they both fit.

Once the cam is removed, you can remove the pop-up stopper and proceed as required to clean the drain. Re-assemble in reverse order. Do not overtighten the cable operator.

For years we have been dealing with sewer gases coming into the house. Sometimes it would get to the point of backup or the toilets would not flush. The city will come in and put the snake out well onto...


I once solved a problem like this -- it was the bathtub drain which had no P-trap on it. This could fit your situation -- when the drain is snaked there is less waste to produce odor. When the line gets sludge in it again, the odor returns.

No p-trap means the odor can come up thru the line with nothing to stop it.

Has anyone checked to see if all fixtures have p-traps? One way to investigate, if you can't see the plumbing, is to run drain water somewhere in the house and see if you can hear the drain water running when you put your ear to each of the plumbing fixture drains.

You would probably have to run the drain water from a fixture which is "in front of" the fixture you are checking so the water would run past it on the way to the main drain.

Sewer Gas Smell Coming From Bath Tub


I can think of two possible solutions to this issue.

  1. The trap is installed incorrectly. The trap is the portion of the drain that is U shaped under the tub. The wastewater must come out of the tub and into the trap. From the trap it goes into the trap arm which must remain horizontal until it reaches the vent. This is very important. The vent must remain vertical until it is at least 6" above the rim of the tub.
  2. The sewer could be plugged. Not the tub but the main sewer line. When this occurs the water has no where to go so it forces the air in the line to take the path of least resistance and that usually menas the tub since the shower has a 2" trap. You may hear a bubbling sound when flushing. The drain may not be completely plugged so it would appear as an intermittent problem.
Hope this helps and please remember to rate this!
