Smart Leak Detection Cost by System Guide
The systems priced apart: inline monitor-and-shutoff, clamp-on monitor-only, and point-sensor sets each stand in their own frame, by main-line size as listed, Frame A counting the single-system install job and Frame B counting packaged multi-sensor installs.

The systems, priced apart by frame
| System form | Frame A reading | Frame B reading |
|---|---|---|
| Inline monitor-and-shutoff | counted inside the installed band, $500-$1,350 | main-line monitor and shutoff counted inside the basic band, $800-$1,500, and the full band, $1,500-$3,000 |
| Clamp-on monitor-only | counted inside the installed band as a monitor-only form, no shutoff line printed | counted inside the package bands as a monitor-only form, no shutoff line printed |
| Point-sensor sets | point sensors at $20-$60 each, as component lines | three sensors counted inside the basic band; a larger set counted inside the full band |
Each reading is one frame's own counting for that system form. Frame A prints its installed band for detection with automatic shutoff and prices point sensors apart; a clamp-on monitor-only form carries no shutoff line in either frame. Frame B counts each form inside its package bands and prints no per-form band apart.
Main-line size, as listed by frame
| Main-line size, as listed | Frame A reading | Frame B reading |
|---|---|---|
| Three-quarter inch | counted inside the installed band | counted inside the package bands |
| One inch | counted inside the installed band | counted inside the package bands |
| One-and-a-quarter inch | counted inside the installed band | counted inside the package bands |
Neither frame prints a separate figure by main-line size. The size is named on a quote as listed, and its reading sits inside the frame's own bands: the installed band in Frame A, the package bands in Frame B.
Frame lines behind the systems, as reported
| Frame line, as published | Frame | 2026 band |
|---|---|---|
| Whole-home detection with automatic shutoff, installed | Frame A | $500-$1,350 |
| Point sensors, each, as component lines | Frame A | $20-$60 |
| Professional fitting labour, where quoted separately | Frame A | $250-$600 |
| Basic setup, three point sensors counted inside | Frame B | $800-$1,500 |
| Full system, a larger sensor set counted inside | Frame B | $1,500-$3,000 |
The system forms price out of these frame lines alone: an inline form out of the main-line lines, a clamp-on form as a monitor-only reading inside the same bands, and a point-sensor set out of the sensor lines in Frame A or the package counts in Frame B.
Systems priced apart, neighbours named apart
A system line answers the system question only inside its own frame, and the product stays the installed monitoring system on every row: a device that senses flow or moisture and alerts, priced as an install job. The neighbours stay apart: leak-location services sit in the slab-leak cluster, plain shutoff-valve replacement sits in the main-shutoff cluster, the sump-pump page's water alarm is a sump accessory line, and shelf-bought sensors with no installation job are not a row here.

Frequently asked questions
What does an inline monitor-and-shutoff system cost, as reported?
Frame A counts an inline system inside its installed band at $500 to $1,350 for whole-home detection with automatic shutoff. Frame B counts the main-line monitor and shutoff inside its basic band at $800 to $1,500 and its full band at $1,500 to $3,000.
What does a clamp-on monitor-only system print at, as reported?
Neither frame prints a separate clamp-on band. A clamp-on monitor-only form is counted inside Frame A's installed band and Frame B's package bands, and no shutoff line is printed for that form in either frame.
What does a point-sensor set print at, as reported?
Frame A prints point sensors at $20 to $60 each, as component lines. Frame B counts three point sensors inside its basic band at $800 to $1,500 and a larger set inside its full band at $1,500 to $3,000, with no per-sensor figure printed.
How is main-line size priced, as listed?
As listed, with no separate figure in either frame. Each size named on a quote reads inside Frame A's installed band or Frame B's package bands.
Are shelf-bought sensors or a leak-location visit priced in this guide?
No, head-on: this guide prices installed monitoring systems alone, and sensors enter only as component lines inside a system install. Shelf-bought sensors with no installation job are not a row here, and leak-location services sit in the slab-leak cluster.
