Gas Line Installation for New Homes in Lewiston
If your new home will use natural gas for heating, cooking, or water heating, BKN Plumbing provides safe and code-compliant gas line installation. This involves running new gas lines from the main supply to all gas equipment. Our licensed plumbers confirm all connections are secure and tested for leaks, adhering to strict safety protocols for gas work.

Rough-In Plumbing Services in Lewiston
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 durable fittings and ensuring all pipes are properly secured and leak-tested before inspection.
Water Heater and Recirculation Installation in Lewiston, ME
New homes commonly 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. Municipal water in Maine is generally soft, but soft, slightly acidic water can slowly corrode copper pipes and cause pinhole leaks. If treatment makes sense for your water, we suggest planning space for a softener or filter loop at the same time.
Guest House, ADU and Addition Plumbing in Lewiston, ME
Guest houses and additions need plumbing that ties into the existing house without overloading old drain lines. We locate the existing sewer, check its condition with a camera and confirm there is enough fall to the new building. Supply lines can be branched from the main house or run as a separate service, based on distance and pressure. We also handle the trenching between structures and repair the yard when we are done.
Sewer and Water Main Connections in Lewiston, ME
Connecting your new home to the municipal sewer and water mains is a key step in new construction plumbing. BKN Plumbing handles all aspects of these connections, including excavation, trenching, pipe laying, and backfilling. We provide proper grading and sealing to prevent future leaks or blockages. Frost heave can shift soil and crack buried pipes, foundations, and outdoor plumbing during the freeze and thaw seasons.
Preventing Common Maine Plumbing Issues in New Builds in Lewiston, ME
New construction in Maine must account for local conditions. Frost heave can shift soil and stress buried pipes, foundations, and outdoor plumbing during the freeze and thaw seasons. We focus on installations that resist shifting foundations and soil movement, which can stress pipes. Municipal water in Maine is generally fairly soft, but soft, slightly acidic water can slowly corrode copper pipes and cause pinhole leaks. We recommend suitable piping materials and treatment options to minimize scale buildup over time, so your new home's plumbing lasts for decades.
Gas Piping for New Homes in Lewiston
We size and install gas piping for ranges, water heaters, furnaces, fireplaces, pool heaters and outdoor kitchens. Black iron and CSST systems are both options, 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 runs at once. The system is pressure tested and inspected before the utility sets the meter.

Plumbing Rough-In Services in Lewiston
The rough-in phase is the foundation of your new construction plumbing system. This involves installing all underground and in-wall piping before concrete is poured and walls are closed. We carefully lay out and connect all water supply, drain, and vent pipes according to architectural plans and local Lewiston codes. Using high-quality PEX or copper piping, we ensure secure, leak-free connections that will serve your property for decades.

Frequently Asked Questions About New Construction Plumbing in Lewiston
Most new single-family homes in the Lewiston 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 itemized bid from your plans.
We typically use PEX-A for water supply because it handles heat and resists the scale and pinhole problems copper can develop with aggressive or hard water. Drains are usually PVC or ABS, depending on local code and builder preference. Copper is an option for mains or exposed runs when you want it.
BKN Plumbing offers a comprehensive warranty on all our new construction plumbing installations. This covers both materials and labor, ensuring peace of mind that your new plumbing system in Lewiston is protected against defects for a specified period after completion.
Frost heave can shift soil and crack buried pipes, foundations, and outdoor plumbing during the freeze and thaw seasons. Soil that shifts and swells with moisture changes can put stress on underground plumbing. We reduce this by using flexible piping materials and proper bedding techniques to help protect against pipe damage from soil movement.
Yes, without exception. All new construction plumbing in Lewiston, ME requires permits from the local building department. This ensures the work meets local codes and standards. BKN Plumbing handles all necessary permit applications and ensures our work passes all required inspections, taking that burden off your shoulders.
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 about $800 to $2,000 depending on layout. It also saves the water that would otherwise run down the drain while you wait for hot water.
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 Lewiston is adept at handling 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 give you the paperwork at final.
