Is this normal?
I have inherited my mothers house. The house was built in 1949 and the land is fairly wet, but if I run say the dishwasher and washer at the same time the water backs up in the bathtub a bit. The septic system is just outside the bathroom. It does ok if I run one thing, but 2 things back up. Is this a normal thing to happen for an older house or is the septic system in need of repair?

Water waste is distributed through your leach field and with the ground being saturated from rains it will not work as effectively, but I don't have water backing up in mine. Leach fields do wear out and not disperse the waste water and will require replacement. When was the last time the septic tank pumped out? I'd call and have it looked at now.

Added: Was this house ever added on to? Your system may be too small.

I agree that when the outside area is wet, the septic doesn't operate as efficiently. Washing machines expel a lot of water at one time, especially the newer ones. It may just be that the drainlines, over this long of a period, have build-up inside them that is slowing the drainage process. The lines are probably cast iron which has rough insides that "catch" things like lint and oils/grease. You may want to try an enzyme drain cleaner such as Draincare by Zep. Enzyme cleaners cling to and "eat" organic waste. Safe for all drainage systems including septics.

got any trees near the septic tank or lines going into it kind of sounds like some roots may have gotten in the line and has it partially blocked so when your pushing a heavy load through it backs up a bit.Also you may want to be sure your gray water(tub,sink,washing mech) are really going to the septic some place they don't epically in older homes (mine) and if thats the case it would be something else
