Sewer and Drainage Systems in New Builds in Kalispell

A dependable sewer and drainage system is essential for any new property. We design and install complete sewer lines, septic systems, and storm drains, ensuring proper grading and connection to municipal services or on-site treatment systems. Rocky ground, clay and gravel are all common in Montana, and rock can make trenching for sewer and water lines slow and expensive. We account for soil movement on your lot, using tough PVC piping and careful bedding to prevent future blockages or pipe damage.

Rough-In Plumbing Services in Kalispell

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.

Guest House, ADU and Addition Plumbing in Kalispell, MT

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 verify there is enough fall to the new building. Supply lines can be branched from the main house or run as a separate service, depending on distance and pressure. We also handle the trenching between structures and repair the yard when we are done.

Water Heater and Recirculation Installation in Kalispell, MT

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. Water across much of Montana is moderately hard to hard, especially from wells, so scale buildup in water heaters and fixtures is common. If treatment makes sense for your water, we recommend planning space for a softener or filter loop at the same time.

Underground and Under-Slab Plumbing in Kalispell

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. Rocky ground, clay and gravel are all common in Montana, and rock can make trenching for sewer and water lines slow and expensive.
