Pasadena plumbing questions
Should old pipes in a Pasadena home be repaired or replaced?
One leak in otherwise sound pipe is usually repaired; when galvanized or failing pipe leaks in several places, repiping costs less over time. Why it comes up in Pasadena: Pre-1950 Craftsman homes still carry galvanized supply lines.
Can recurring clogs in Pasadena mean a sewer line problem?
Yes. When several drains back up together, the main sewer line is the likely cause, and a camera inspection shows whether it's roots, a sag or a break. Why it comes up in Pasadena: Clay laterals under mature street trees crack and fill with roots.
Where does Pasadena, California's water come from?
About 60% is imported through Metropolitan Water District and about 40% is Raymond Basin groundwater from city wells.
Should I repipe my Bungalow Heaven Craftsman?
If it still has galvanized pipe, low pressure and rusty water are the signs. Repiping through walls can be done without changing historic exteriors.
Why do Pasadena sewer laterals fail so often?
Old clay pipes under large street trees let roots in at the joints. A camera inspection shows whether lining or replacement is needed.
Do Linda Vista hillside homes have pressure problems?
Elevation changes can push street pressure high or low. A regulator near 60 psi protects pipes and fixtures.
