12-Inch Cast Iron Wet Taps Completed in Mounds View

Cast iron mains are their own challenge. The material is old, sometimes brittle, and it doesn't forgive sloppy work. When we got the call to complete two wet taps on a 12-inch cast iron line in Mounds View - a 12x4 and a 12x1.5 - we knew the planning had to be solid before we ever broke ground.

A wet tap, or hot tap, lets us connect directly into a live pressurized line without shutting the system down. That matters a lot. No service interruption. No disrupting the surrounding area more than necessary. The water keeps flowing while we do the work - and that's the whole point.

Old cast iron adds a layer of complexity that newer pipe materials don't. You're working with a line that may have years of buildup, varying wall thickness, and less predictable behavior under pressure. Getting two taps done cleanly on the same main takes experience and the right equipment - not just effort.

Both connections came out clean. The valve and fittings are seated properly, the hardware is tight, and the system stayed live throughout. That's what good wet tap work looks like - nothing dramatic, just precise execution and a job that holds up long-term.

This is the kind of utility work that keeps infrastructure running without causing unnecessary headaches for the surrounding system or community. If you've got a live main that needs a new connection, that's exactly what we do.
