I recently removed a drain plug device for my upstair bathroom sink and removed the trap to clean out my girlfriends hair that clogs the drainage. Since, I have done this I am getting a sewage smell especially when I am running water. What can I do?
Somewhere a drain connection came loose. Check in the basement and see if you can locate it and put it back together yourself if you think you are handy enough. Otherwise it would probably be easier to call a plumber.
It could be just from the pipe its self, rather than sewer gases.Try making sure everything is connected properly. Then if that doesn't do the trick ...if you want try if its plastic PVC pipe soak it in a disinfectant or some type of cleaner to deodorize that trap.....if dont want to go through the trouble, just replace the trap.
in case you activate the faucet, and enable it run for a jiffy does the scent stop. If it does then the main undemanding venture would be a blocked vent pipe and while the lavatory in that line is flushed the only way that the water will pass down is to suck the water out of the traps letting sewer gas up into your house. that's something that the construction superintendent desires to repair. you do no longer point out that the sink drains slowly so i do no longer assume that it is plugged with hair, in case you seem down the drain each and every so often you could discover the hair there. i could block the overflow, just about fill the sink with water, pass away the water working, pull the plug, and attempt applying a plunger to loosen the blockage so as that it washes away.
Make sure the trap is working properly. The trap needs to maintain water in order for it to stop venting up sewerage. if there is too much of a drop from the sink to the bottom of the trap it will siphon some of the water out of the trap leaving a air gap which will aspirate and vent up. unless there is something still in the sink or pipe before the trap causing the smell, the system is not vented or its not trapped properly. good luck
