Cast iron and ductile iron pipe was long a lower-cost alternative to copper, before the advent of durable plastic materials but special non-conductive fittings must be used where transitions are to be made to other metallic pipes, except for terminal fittings, in order to avoid corrosion owing to electrochemical reactions between dissimilar metals (see galvanic cell).
The next day, I had an unrelated incident with a sprinkler valve inlet pipe rupturing, due to corrosion (galvanized pipe. Since this situation caused me to lose water service to the house, Charlie sent someone over that day to do an emergency cap off. It was then explained what could be done to provide a permanent fix (basically replacing the old galvanized pipe and creating a new sprinkler valve manifold). A quote was given and the full repair was scheduled for the following day. All is good now, and the job came out $120 below the estimate.
Sometimes you might need your sewer and drain lines inspected. For instance, if your sewage is backed up, then you probably want to determine what the cause is. In instances where we can't physically get to the problem to see what it is, we can use a sewer video camera to go down into your lines and take a video showing us what's the issue then. That way we'll know the appropriate way to deal with it.
