bad smell from laundry room and water heater tank room

[ttaiko]

Hi, I live in a condo. today I noticed bad smell like urine in my loundry room and the same smell in water heater tank room. it's really bad smell, but I can not figure out where exactly the smell is coming from. Does anyone have any idea? please help!

If you have a floor drain for use in case of overflow, which would be very likely in a condo, it has dried out and needs a liquid poured into it.

no, no floor drain. it has draing pipe on the wall about 40"H from the floor. and water heater tank has the same about 30"h from the floor. it's the same odor in 2 different rooms... but they are back to back of each other.

By what you are saying it sounds to me like the T&P Valve on the water heater is going into a standpipe similar to what a washing machine uses.

I would venture a guess there is no water in the trap of this drain. Test your T&P Valve and your problem will be solved for now as long as the T&P Valve closes again.... Or, pour some water in it.

Redwood&hj,
so I need to pour water into the drain where the discharge pipe line is goint into?
just regular water is fine? how do I test T&P valve?
Thank you so much for your help both of you!

Your laundry room does not have a washing machine in it? If not, then that is the same as having a dry floor drain, except it is the laundry drain's trap.
