Water Heater and Recirculation Installation in O'Fallon, MO
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. Homes around O'Fallon on private wells should test for hardness and bacteria before picking a filter. 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 O'Fallon
The cost of new construction plumbing in O'Fallon 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.
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 O'Fallon.
Hot, humid summers and cold winters give Missouri plumbing a wide range of stress, with big temperature swings in between. Disconnecting hoses, insulating exposed lines and letting faucets drip on bitter nights head off most freeze damage. We select materials and installation methods that can handle local conditions, insulating pipes and burying lines at adequate depths where freezing is a risk. We also use materials that can handle thermal expansion and contraction, helping prevent leaks and bursts.
The plumbing rough-in phase for a typical residential build in O'Fallon generally takes 1 to 2 weeks, depending on the crew size and complexity. The final fixture installation and trim-out generally takes an additional 2 to 4 days later in the construction schedule.
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.
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.
Yes, our skilled team can assist with the plumbing design and layout for your new home. We work with your architectural plans to optimize water flow, drain efficiency, and fixture placement. Our goal is to create a functional, efficient, and code-compliant plumbing system that meets your family's needs.
For new construction plumbing, we mainly use PEX piping for water supply lines due to its flexibility, durability, and resistance to scale build-up. For drain, waste, and vent systems, we use PVC pipes, which are resistant to corrosion and long-lasting.
