New Construction Plumbing

Plumbing

Rough-in decides what the house lives with

Everything difficult about a house’s plumbing gets decided before the slab is poured. We work with builders who want it done right the first time.

New Construction Plumbing work performed by Merckle Plumbing in Freeport, Florida

New construction plumbing runs in stages that follow the build. Underground goes in before the slab, drain, waste and vent set in place and inspected while everything is still visible. Then rough-in, the supply lines and remaining DWV inside the framed walls, pressure tested and inspected before drywall closes it up. Then trim, when the fixtures actually get set and the house becomes usable.

The underground stage carries the most weight, because Florida builds on slab. Once concrete is poured over that drain layout, every line in it is committed. Grade, pipe support, correct slope and accurate fixture locations either happen then or become a very expensive conversation later. A quarter inch of wrong slope is invisible on the day and a recurring drain complaint for the life of the house.

Our job is also to keep your schedule intact. Plumbing sits between excavation, concrete, framing and drywall, and a plumber who is not there on the day the slab is scheduled holds up everyone downstream. We show up on the day and we leave the work inspection ready.

Where we fit into your build

  • Underground DWV set and inspected ahead of the slab pour
  • Water service from the meter or well into the building
  • Top-out rough-in of supply and vent inside the framed walls
  • Gas piping run for range, dryer, water heater or outdoor kitchen
  • Tank or tankless water heater set, vented and connected
  • Fixture trim, faucets, toilets, tubs and disposals at finish stage
  • Grinder pump or force main connection where the utility requires one

Once the slab is poured, the drain layout is permanent. Everything after that is working around it.

What building here demands

Slab-on-grade is the default in Florida, and it changes the risk profile of the whole job. Supply and drain lines under the slab cannot be inspected visually once the pour is done, which means a leak years later needs electronic or acoustic detection and then either a spot repair through the concrete or an overhead reroute. Neither is cheap. That is the entire argument for careful support, protection and testing before the pour, and it is why we do not rush that stage.

Sewer connection depends on where the lot sits. Regional Utilities runs both gravity sewer and low pressure force main across this area, and lots on force main need an individual grinder pump at the house. That is very common in the low, flat ground around Freeport and through the 30A corridor. It affects the underground layout, the electrical coordination and what the homeowner gets handed at closing, so it needs settling early rather than discovered late.

Then the water itself. The municipal supply here is drawn from wells, and some parcels outside the franchise are on private wells entirely. Mineral content is a familiar local concern, which shapes conversations about water heater choice and whether filtration is worth roughing in while the walls are still open. It is far cheaper to run that provision now than to retrofit it after the owner moves in.

Stages of the work

  • Plan review and coordination

    We read the plans, flag anything that will fight with the framing or the truss layout, and get our dates onto your schedule.

  • Underground rough

    DWV laid out, sloped, supported and protected, with fixture locations verified against the plan before anybody calls for concrete.

  • Pre-pour inspection

    Tested and inspected while it is all still visible. This is the checkpoint that protects the owner for the life of the house.

  • Top-out rough-in

    Supply lines and remaining vent run through the framing, secured, protected at plates, pressure tested and inspected before drywall.

  • Gas and appliance provision

    Gas runs sized for the actual appliance load, water heater location prepared, tank or tankless as specified.

  • Trim and final

    Fixtures set, connected and tested, water heater fired, everything checked and handed over ready for final inspection.

Where we work

Building with contractors across Walton and Okaloosa

We work new construction in Freeport, Santa Rosa Beach, Point Washington and the 30A communities including WaterColor, Seaside, Grayton Beach, Seagrove Beach and Inlet Beach, plus Miramar Beach and Destin. Coastal builds bring their own set of considerations, elevated foundations on some lots, tight infill sites where staging is a puzzle, and force main sewer areas where a grinder pump has to be planned into the design rather than added at the end.

Inland we build around DeFuniak Springs, Paxton, Ponce de Leon and Choctaw Beach, and north into the Washington and Holmes County towns of Vernon, Ebro, Caryville and Westville, where private wells and septic systems come into play more often. Noah holds Florida plumbing certification CFC1429646 and mechanical certification CMC1250426, so on projects where both trades are in scope you are coordinating with one contractor across the whole build instead of chasing two schedules.

Towns we get to most: Freeport, Santa Rosa Beach, Point Washington, Miramar Beach, Niceville, Destin, Eglin Air Force Base, Valparaiso, Ebro, Vernon, Caryville. See the full service area.

Questions

Questions we get about this

Do you work with builders on multiple homes at a time?

Yes. Repeat work with a builder is easier for everyone, since we already know your specs, your inspector and how your schedule runs. Tell us what your pipeline looks like and we will be straight about what capacity we have.

Can you handle both the plumbing and the HVAC?

Yes, and that is a real advantage on a build. Noah holds both the plumbing certification CFC1429646 and the mechanical certification CMC1250426, so condensate routing, water heater venting and gas provision get coordinated by one contractor instead of two trades meeting at the drywall stage.

What if the lot needs a grinder pump?

A fair number of lots here do, because Regional Utilities runs low pressure force main in the flatter areas. It changes the underground layout and needs electrical coordination, so it is worth settling at plan review rather than discovering during underground rough.

Do you handle permits and inspections?

Yes. Permitting, calling inspections and being on site for them is part of the job. Underground and rough-in inspections happen at points where the schedule cannot afford a failure, so we leave the work ready for them.

Can you rough in for a tankless heater or a filtration system?

Yes, and doing it during the build is far cheaper than retrofitting. Tankless needs its gas line sized and its venting path planned early. Filtration is worth discussing given the mineral content in our well drawn supply.

Do you do remodels and additions as well?

We do. Additions and gut remodels have most of the same stages compressed into a smaller footprint, with the extra puzzle of tying new work into whatever is already there. Older homes may still have cast iron drain line, and that is worth camera inspecting before you build onto it.
