Water Service Size Planner

Count your fixtures and see a planning size for the water service line.

These tools give planning-level estimates from typical values. They are not quotes, designs or engineering, and results depend on your actual soil, depth, access, local rules and conditions. Only a visit can confirm what a job needs, and we give you a clear price before any work begins.

How it works

Four quick steps.

  1. 01

    Count fixtures

    Bathrooms, kitchens, laundry, hose bibs and irrigation.

  2. 02

    Enter the run

    Length from the main to the house.

  3. 03

    Add special loads

    Irrigation zones and fire sprinklers.

  4. 04

    Read the size

    A planning size for the service line.

Tips

  • Long runs lose pressure, so they often need a larger line.
  • Irrigation and fire sprinklers can change the answer a lot.
  • The utility and plumbing code set the final size.
Questions

About this tool.

Is this a design?

No. It is a planning guide using a simple fixture count. A plumber or engineer sizes the line.

What size is a typical house service?

Many houses use three-quarter inch or one inch. Larger homes and long runs may need more.

Does pressure matter?

Yes. Low pressure at the main or a long run can call for a larger line.
