Plumbing in Willow Glen
Two neighborhoods in one
On some Willow Glen streets the houses are older bungalows and revival homes with crawl spaces, galvanized supply lines and clay laterals. On others, especially in the Eichler tracts, the houses sit on slabs with copper or steel pipes under the floor and hot water heating loops cast into the concrete.
The same symptom can mean different things in each. A damp floor in an older house points to a supply or drain leak; in an Eichler it may be a radiant heating loop. We ask what kind of house you have before we come out, so the right tools come with us.
Water and pipes
Willow Glen's Eichler tracts
San Jose has about 500 Eichler homes built between 1951 and 1962 in five tracts, and over 300 of them, including Fairglen, are in Willow Glen. The Fairglen Additions, 218 Eichler houses built from 1959 to 1961, are listed on the National Register of Historic Places. Eichlers are slab-built with radiant heating pipes embedded in the slab, so a warm, damp patch can be a heating loop rather than a water line.
Houses and pipes
Older Willow Glen houses
Outside the Eichler tracts, many Willow Glen homes are older and still run galvanized supply lines that have narrowed with rust. Low pressure throughout the house and brown water after a vacation are the usual signs. Crawl spaces make repiping these houses practical without opening many walls.
The neighborhood's mature street trees are part of its character, but their roots find every joint in an old clay lateral. A camera inspection before any sewer repair shows exactly where the roots are and whether lining, spot repair or replacement makes sense.
