Pipe Repair in Top of the Hill, Daly City, CA
Mixed-era plumbing is the defining feature here, and dissimilar metal joints are the defining failure. Where copper meets galvanized without a dielectric union, the joint corrodes rapidly — and in Daly City's damp, considerably faster than it would inland.
What is a dielectric union and why does it matter in my home?
It is a fitting that separates dissimilar metals so they do not corrode each other. Where copper was joined directly to galvanized during a past renovation, that joint fails early. Adding the union at repair prevents a repeat.

Both, depending on the run and what's already there. We match existing material where it makes sense and explain the trade-off when a change is worth considering.
