A Running Toilet in City Heights, San Diego
A toilet that keeps running has a worn flapper, a bad fill valve, or a chain and float out of adjustment. These are wear parts, most running toilets are a flapper or fill-valve swap, not a plumbing tear-out..
1920s Craftsman stock, plaster and original-trim repair.The mesa climate is mild, but the housing is old. Most homes date to the 1910s through 1940s, built with lath-and-plaster walls, original wood windows and doors, and period trim and hardware that has to be matched rather than swapped for box-store parts. Decades of settling leave their own cracks and out-of-square openings.
The apartment corridors along University Avenue, Fairmount Avenue, and El Cajon Boulevard run steady turnover work: door and latch repair, drywall patching, and fixture replacement between tenants. The bungalow blocks in the Azalea Park and Fairmount Park pockets carry original plaster and trim that need matched patching rather than drywall substitution.
