Sewer and drain help for older Grant homes in Salem 97301

Grant is one of Salem's older neighborhoods, a grid of bungalows, foursquares and cottages a short walk north of the Capitol Mall. Many of these homes were built between the early 1900s and the 1930s, and much of the original plumbing is still underground. If your basement stair or crawlspace shows old pipe running across the joists, you are looking at history that still carries water.

The calls we get from Grant follow a pattern. A toilet gurgles when the washer drains, the basement floor drain seeps after a heavy load, or the kitchen sink empties slowly no matter how many times it gets plunged. Most of the time, the cause sits between the house and the street, in a sewer lateral that roots found long ago.

What a century under the street does to a sewer lateral

Clay sewer pipe was laid in short sections with mortar or packed joints, and those joints soften with age. Grant's mature maples and oaks send fine roots into every gap, where they thicken into a mat that snags paper. Root cutting reopens the line, but a camera often shows offset joints, cracks or a belly where water sits, and those spots decide whether cutting will hold.

Inside the house, galvanized supply pipe from the same era rusts from the inside, so water pressure fades at the upstairs shower before anything leaks. Cast-iron drains under the first floor can crack along the bottom. Where a remodel happened, you may also find copper, PEX and plastic drain spliced into the old system, and every transition is worth a look.
