A different kind of plumbing challenge

Downtown Fullerton and its surrounding residential blocks are older than the hillside neighborhoods to the north. Homes here range from early twentieth-century houses to postwar infill, many updated more than once. That history leaves a patchwork: some pipe original, some replaced, and sometimes several materials in one house.

The land is flatter than Coyote Hills, so dramatic pressure differences from elevation are less common. Pressure problems here more often come from restriction inside old pipe, an aging regulator or valves that no longer open fully.

At a glance

Housing
Older homes, many remodeled over the years
Foundations
Raised floors are common in older homes; postwar homes may be slab
Supply
Galvanized, copper or newer materials, often mixed
Laterals
Clay or cast iron in many older homes
Water service
Fullerton's city water utility

Common symptoms and likely causes

  • IfGood static pressure but weak flowThenRestriction in old supply pipe or a failing valve.
  • IfBrown water after the water has been offThenCorroding galvanized pipe.
  • IfRepeated sewer clogsThenRoots or broken sections in a clay or cast-iron lateral.
  • IfDamp crawl spaceThenLeak in supply or drain lines under the floor.

A sensible order of operations for an older home

  1. Map what you have.Have a plumber identify pipe materials, the shutoff, any regulator and the cleanout.
  2. Measure.Static and working pressure readings show whether restriction is the issue.
  3. Inspect the lateral.A camera run is often worthwhile before other drain work.
  4. Prioritize.Address active leaks and safety items first, then flow and pressure.
  5. Plan permits.For repipes and line replacement, check with the City of Fullerton.

Questions to ask

  1. How many pipe materials are in this house, and where do they meet?
  2. Is the crawl space accessible for repairs and rerouting?
  3. What does the lateral camera show?
  4. Which repairs are urgent and which can be planned?

Common questions

Is downtown part of this site's hillside focus?

It is a nearby area with different terrain. Pipe age makes many of the same pressure and flow questions relevant.

Are raised floors easier for plumbing work?

Often, because pipes can be reached from below. Access conditions vary by house.

Do older homes need regulators?

It depends on incoming pressure. A gauge reading answers it.
