Sewer and Drainage Systems in New Builds in Portsmouth
A reliable sewer and drainage system is essential for any new property. We design and install complete sewer lines, septic systems, and storm drains, making sure of proper grading and connection to municipal services or on-site treatment systems. Most homes have basements, so foundation drainage and sump systems matter for keeping the lower level dry. We account for soil movement on your lot, using tough PVC piping and careful bedding to prevent future blockages or pipe damage.

Rough-In and Top-Out Plumbing in Portsmouth, NH
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.
Rough-In Plumbing Services in Portsmouth
The rough-in phase is where the core plumbing system is installed within the walls, floors, and ceilings before drywall. This includes all supply lines, drain lines, and vent piping for every fixture. Our plumbers meticulously plan and execute the rough-in, using high-quality fittings and ensuring all pipes are properly secured and leak-tested before inspection.

Gas Piping for New Homes in Portsmouth
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. We calculate total BTU load and pipe length so every appliance gets enough pressure even when everything is running together. The system is pressure tested and inspected before the utility installs the meter.

Frequently Asked Questions About New Construction Plumbing in Portsmouth
The cost of new construction plumbing in Portsmouth varies widely based on the size and complexity of the project, number of bathrooms, and fixture choices. For a standard 3-bedroom, 2-bathroom home, rough-in and finish plumbing can range from $10,000 to $25,000. Commercial projects or luxury homes with advanced systems run higher.
The timeline for new construction plumbing depends on the project's scope. The rough-in phase, which involves installing the hidden pipes, usually takes 1 to 2 weeks. The final fixture installation and connection usually takes another 3 to 5 days, spread out during the later stages of construction. We work closely with your general contractor to stay on schedule.
For new construction, we usually use PEX, or cross-linked polyethylene, for water supply lines due to its flexibility, durability, and resistance to corrosion. For drain, waste, and vent systems, we mostly use PVC piping because it's strong, lightweight, and cost-effective.
Plumbing is often covered under the general building permit, but we handle the plumbing inspections and any separate plumbing or gas permits your jurisdiction requires. We hold the licenses New Hampshire requires for plumbing work. Our team schedules each inspection and meets the inspector on site.
Our workmanship is warrantied, and the warranty terms are spelled out in your contract. Fixtures, water heaters and PEX systems also carry their own manufacturer warranties, often 10 years or more for PEX and fittings from brands like Uponor. We give you the paperwork at final.
We install a wide range of reputable plumbing fixture brands, including Moen, Kohler, Delta, American Standard, and Toto. We can work with any brand you specify or recommend options that fit your budget and design aesthetic for your new build in Portsmouth.
Choosing a local plumber like FVR Plumbing for new construction in Portsmouth means familiarity with local building codes, soil conditions, and municipal inspection processes. We understand the climate and infrastructure challenges in New Hampshire, providing focused and efficient service.
FVR Plumbing stands behind our new construction plumbing work with a solid warranty on both labor and materials.
