Final Trim and Fixture Setting in Topsham
At trim we install toilets, faucets, garbage disposals, dishwashers, ice maker boxes and laundry connections. We work with fixtures from Moen, Delta, Kohler, American Standard and the other brands builders commonly specify, or with owner-supplied fixtures. Every fixture is checked for flow, drainage and leaks, and angle stops are set straight and tight. We finish by running every fixture at once to confirm the system drains and vents properly under load.

Water Heater Installation for New Builds in Topsham
Selecting and installing the right water heater is essential for any new construction. We provide expert installation of traditional tank-style and tankless water heaters, considering your property's hot water demands and energy efficiency goals. Our plumbers ensure correct sizing, venting, and gas or electrical connections, adhering to all safety regulations for new homes in Topsham.
Underground and Under-Slab Plumbing in Topsham
The underground phase sets the drain, waste and vent layout that every fixture in the house will depend 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. Basements are standard in most Maine homes, and groundwater and spring thaw make sump pumps and drainage important. We compact bedding carefully and avoid rigid points that could stress the pipe as the ground moves. Each line is water tested and left visible for the inspector before your concrete contractor pours.
Fixture Installation and Trim-Out in Topsham, ME
Once the rough-in is complete and walls are up, our team returns for fixture installation and trim-out. This includes connecting sinks, toilets, bathtubs, showers, dishwashers, and water heaters. We ensure all fixtures are properly seated, sealed, and functional, providing a professional finish to your new construction plumbing. We work with many brands like Moen, Kohler, and American Standard to match your design specifications.
Gas Piping for New Homes in Topsham
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 sets the meter.
Gas Line Installation for New Construction in Topsham, ME
Proper and safe gas line installation is a key component of new construction plumbing. Our certified technicians install new gas lines for appliances like furnaces, water heaters, stoves, and outdoor grills. We use approved materials and conduct rigorous leak testing to ensure the safety and integrity of your gas system, meeting all Maine and local Topsham codes.
Residential New Construction Plumbing in Topsham
BKN Plumbing focuses on complete plumbing system installations for new residential homes. This includes designing the layout, installing all water supply lines, drain lines, and vent piping. We work closely with homeowners and builders to ensure the plumbing system is tailored to the home's specifications and future needs, using materials like PEX and copper for supply lines and PVC for drains, chosen for durability in Maine climate.

Water Heater and Recirculation Installation in Topsham, ME
New homes often use tank water heaters in the garage, basement or utility room, or tankless units on an exterior wall. We size the heater to your bathroom count and install gas or electric connections, venting, an expansion tank and drain pan where required. Many owners add a dedicated recirculation line during rough-in, which is much less expensive than retrofitting later. Private wells serve a large share of Maine homes, and arsenic, radon, and iron make regular well water testing important. If treatment makes sense for your water, we suggest planning space for a softener or filter loop at the same time.

Frequently Asked Questions About New Construction Plumbing in Topsham
Most new single-family homes in the Topsham area cost between $12,000 and $25,000 to plumb, with larger custom homes running $30,000 or more. Fixture count, pipe material, water heater type and extras like recirculation or outdoor kitchens drive the final price. We provide an detailed bid from your plans.
Common challenges in new construction plumbing include coordinating with other trades, working around site-specific conditions like rocky soil or foundation types, and ensuring strict adherence to evolving building codes. Our experienced team in Topsham is adept at navigating these complexities.
Our workmanship is warrantied, and the warranty terms are listed 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 hand over the paperwork at final.
Yes, we can handle only the underground, only rough-in and top-out, or only trim. If another plumber started the job, we will inspect and test their work before taking it over. That protects you and keeps the inspection record clear.
Some jurisdictions allow owner-builders to do their own plumbing on a home they will live in, but the work still has to pass every inspection. Under-slab and gas work are the hardest to get right and the most expensive to fix later. Many owner-builders hire us for those phases and finish easier tasks themselves.
We can run a dedicated return line during rough-in so hot water reaches distant bathrooms in seconds. A dedicated line works better than retrofit crossover valves and adds roughly $800 to $2,000 depending on layout. It also saves the water that would otherwise run down the drain as you wait for hot water.
