sewer gasses?

Question

i have a septic tank at home .. have gone over everything .. traps , vents, etc .. still get bad smells on one end of the house by the kids bathroom only ..... i was wondering if over use could cause the smell to back up in the house .. the kids have an awful lot of friends over all day and they are constantly flushing and using the bathroom... is this to much for the septic system to handle????

where would i find the trap under the house... is it the main drain pipie for the whole house???

this problem comes and goes ... it might be days or a couple weeks with no smell then suddenly it is there .. and it only seems to come late in the evening and is real bad early in the morning ... the rest of the day .. say after 10 in the morning there is no smell

Answer 1

is there a u shaped trap under the house preventing gases from entering. sounds like not. I worked for a city engineering department and we "smoke tested" our sewer lines in the street to find broken lines...occassionally a housewould fill with smoke because their plumbing either contained a dry trap (unused sink or something) or they had no trap and the sewer smell (and our smoke) entered the building...

Answer 2

Overuse by itself would not cause you to get sewer gasses into the house. Typically sewer gasses would be present if you had a plug in your vent (so maybe when the toilet is flushed you suck out the seal in the p-trap of the sink or bathtub), you have a p-trap that hass dried out (like a floor drain), or you have a broken vent line. There is also a possibility the seal on the toilet has broken.

Answer 3

There should not be a trap under the house. each fixture (sink, toilet etc) has it's own trap and that is all that is needed. With kids and lots of use, the toilet there may have been rocked or otherwise moved and the wax seal under the toilet has failed. If you have access under the bathroom, check for water leaks.
