Rattling Pipes in Middle of the Night

[Vincent]

Our home is 8 months old. It is two floors and built on a slab. For the past two months, at least 1-3 times a week and always at night or early morning, we hear what sounds like a jackhammer. It rattles the side of the house loud enough to wake us. It seems to be coming from the same side of the house as the laundry room. It seems to happen more often than not after we use the washing machine. It happens when there is no water running and the furnace is off. We talked to the plumber who was the vendor on our home and he says it is impossible to have rattling pipes unless water is being turned on our off. We have no clue what to do next. Any help is very much appreciated.Thank you.

Some locals have pressure beyond 80 psi and perhaps higher at night when the water towers are filling up causing added pressure. A pressure reducing valve would be a help in this case. Air chambers or expansion tanks can be added to soften water hammer. Pipes that are loose can be found and secured better. I hope this helps Terry Love
