Plumbing FAQs - Strange Smells

Question: There is a strange smell coming from our guest bathroom that we rarely use, what is causing this and what can we do?

Answer: If the bathroom is rarely used - there is a good chance that the water in the trap of the sink, tub or shower has evaporated.  Traps are designed to hold water and keep out these foul odors and sewer gases.  Running the water down the drain periodically in these rarely used fixtures, will keep water in the trap and eliminate these odors.
