From time to time we have had residents that have noticed a foul odor generally emanating from the Jacuzzi tub or the guest bathroom tub.
Here is why.
Every drain has some sort of water trap. The water in the trap essentially seals the drain. If the drain has no water in the trap, then it is open to the sewer.
Guess what, sewer gas is lighter than air and it will come up through the drain, hence the bad smell.
Where does the water go?
Well most folks don’t use their Jacuzzi tub or maybe their guest bathroom tub and the water in the trap just evaporates.
How do you prevent the problem?
At least once a month run a little water through the drain. That will replenish any water that has evaporated and keep you drain properly sealed.
