Housing and plumbing at a glance
The residential streets near Downtown Fullerton include homes built across many decades, including some older than the mid-century tract homes found in much of north Fullerton. Older houses here may sit on raised foundations with a crawlspace, while later homes are more often slab-on-grade.
Because these homes have been lived in and remodeled for a long time, it is common to find several generations of plumbing in one house. Treat the details below as general patterns and check your own property, since every house differs.
What you might find
| System | Common in older homes | What to check |
|---|---|---|
| Supply lines | Galvanized steel, copper, or later plastic repairs | Water color, pressure and leak history |
| Drain lines | Cast iron inside the house | Slow drains, rust stains, odors |
| Sewer lateral | Clay or cast iron | Roots, cracks and recurring clogs |
| Foundation | Raised with crawlspace, or slab | Crawlspace access or slab leak signs |
Raised foundation versus slab
Raised foundation
- Pipes run through a crawlspace.
- Leaks can often be seen and reached from below.
- Crawlspace access should be kept clear.
Slab-on-grade
- Some lines run under or within the concrete.
- Leaks are hidden and need locating.
- Repairs may mean opening floors or rerouting.
Worth doing in an older downtown-area home
- Find and test the main shutoff.
- If there is a crawlspace, look for damp soil or drips under bathrooms and the kitchen.
- Note any trees near the sewer path.
- Ask about a sewer camera inspection if drains clog repeatedly.
- Check that the water heater has seismic straps.

Common questions
Are downtown-area homes more likely to have old pipes?
Older homes generally have had more time for pipes to age and be patched. An inspection tells you what your house actually has.
Is crawlspace plumbing easier to repair?
Often it is easier to reach than under-slab pipe, though access can still be tight.
