Sewer Gas

I had a hot water tank replaced and they flushed the tank into the floor drain. The top of the drain sits about 5-6 inches down in a trench in some fairly new concrete. Well the top of the floor drain was covered with sand, which was scraped clean to drain that hot water tank. Since then I have had sewer gas smell leaking into the house, being pulled into the whole house by the furnaces nearby. Some days are worse than others. I have tried dumping anywhere from a couple glasses to a gallon of water into the trap in hopes of stopping the smell. I am not sure if this is a modern style trap, the house is 121 years old.

Any ideas?

Re: Sewer Gas

Howdy, how much sand? have you ever used the drain before? Is there a vent stack pipe close by that this floor drain is tied into? Try pouring a quart of water into the drain an see of the gas smell goes away temporaryly- if there is a p trap it sould fill and stop if not call a plumber...

Re: Sewer Gas

Timothy-

Thanks for the reply. The drain is actually situated under my work bench. I wiggled my way under there and poured in water. The water stayed for about 2 days and then dried up. The drain is not very deep, only about 4-5 inches. I am going to get a dehumidifier to keep a constant drip into the drain.
