Monday, August 18th, 2008 01:59 pmI've been trying to figure out a mystery of why my bathroom sink drain would smell slightly like sulfur after turning the cold water on in the mornings or after the sink wasn't used for a while... and the kitchen sink drain too. It started happening after I plugged a small leak in one of the drain pipes in the basement. I've been thinking it could be a problem with the main vent stack, but normally there would be other clues if that were the problem, which haven't been the case for me. And the kitchen sink has its own vent stack, anyway, which I noticed today. I removed the plug I had put in the pipe, and the smell went away. Now I put the plug back in, to see if the smell comes back again. It's hard because it's one of those things you have to wait several days to test out.
The basement is a maze of pipes, vents, and cables. Whenever I go down there, I notice something I did not notice before, or figure out how something is connected, which I had not realized before.
It is boggling how many different pipes and lines there are down there, criss-crossing everywhere. Input cold water lines. Hot water lines. Drain pipes. Vent pipes. Gas lines. Heater exhaust pipes. Insulated HVAC ducts. Uninsulated HVAC air input ducts. Power cables. Telephone cables. A bunch of other old cables lying around which probably used to be connected but look like they aren't anymore.
The water lines and drains go to and from each and every fixture that uses water - the sinks, the toilets, the tub, the washing machine, the dishwasher, the refrigerator (even though I don't use the water from the fridge dispenser).
Then there are the vents on the roof and side of the house. The drain vent stacks. The heater exhaust / the shower fan ... haven't figured out yet whether those 2 are using the same vent or not ... the stove vent, the oven vent (since the oven is an enclosed fixture), the dryer vent, the water heater exhaust vent.. the attic fan...
