Gas Piping for New Homes in Marysville

We size and install gas piping for ranges, water heaters, furnaces, fireplaces, pool heaters and outdoor kitchens. Black iron and CSST systems are both available, and CSST is bonded per manufacturer and code requirements.

The system is pressure tested and inspected before the utility installs the meter.

Permits and Inspections for New Plumbing in Marysville, WA

FHN Plumbing handles all necessary plumbing permits and coordinates with local Marysville inspectors throughout the new construction process.

Underground and Under-Slab Plumbing in Marysville

The underground phase sets the drain, waste and vent layout that every fixture in the house will rely on. We trench, bed and slope PVC or ABS drain lines at a minimum quarter inch per foot and protect every pipe that passes through the slab or foundation with sleeves. Glacial till and dense hardpan are common in western Washington, and they drain poorly enough to keep water against foundations and in crawlspaces. We compact bedding carefully and avoid rigid points that could stress the pipe as the ground moves. Each line is water tested and left exposed for the inspector before your concrete contractor pours.

Rough-In and Top-Out Plumbing in Marysville, WA

Once framing is up, we run supply and vent lines through the walls and attic and set every stub-out for sinks, tubs, showers and appliances. We typically install PEX-A with a central manifold so each fixture gets its own line and shutoff. Shower valves are set at the heights you choose, and tub sets are installed and protected before the drywall is hung. A full pressure test is held for inspection so nothing hidden in the walls is ever a question.
