We have been in our new house the two years since it was built. We have a septic tank. Recently, when I put the washing machine on the guest room toilet adjacent to laundry room started to gurgle, occasionally with soap suds in the water. Today I noticed when my husband was in the shower on the other side of the house the same bathroom and kitchen sink were gurgling. Can you help?

You have clogged drain, snake it from the roof vent, rod enough to reach from the roof to the basement floor plus 20 feet extra, good luck.
