I have roto rooter coming tonight to unplug my main sewer line, because when I use any water in the house it backs up into the utility sink in the basement. The washing machine drains into this utility sink. We noticed after doing wash that the sump pump was going back on every 30 seconds and there was soapy water in the sump pump basin, but the basement floor was completely dry. The sump pump empties out in the backyard about 20 feet from the house.

How would water get from the sewer into the sump pump basin? Could there be an overflow from the sewer that empties into the basin? Or is this a sign that there could be some sort of break in the sewer main near the house?

Thanks in advance for the help.

I bought a 50+ year old house and have decided to replace the hardwood floors. The subfloors are really squeeky, the hardwoods are separating in places and there are large gouges in spots. I plan on tearing up the old floors and wonder what to do with the existing tongue-and-groove subfloors. Should i tear the subfloor up and replace it with new exterior-grade plywood screwed and glued with Liquid Nails for subflooring? Or should I just try screwing the tongue-and-groove subfloor down and install right over it? Any other suggestions?
