Stroll by any downtown, together with main metro areas resembling Chicago, and the sample is obvious. Workplace area is sitting empty whereas housing demand continues to rise.
Builders are responding by changing industrial buildings into residential models, motels, and mixed-use areas. Workplace-to-residential conversions have reached about 25,000 models nationwide, with Chicago now main the pattern.
In keeping with RentCafe, 90,300 residences had been within the technique of conversion nationwide, up 28% from 70,600 a yr earlier, marking one other document yr for office-to-apartment initiatives.
For contractors, these initiatives create alternative, however in addition they elevate a sensible query: How do you put in residential plumbing in buildings that weren’t designed for it?
The problem comes all the way down to plumbing
Design and incentives could drive these initiatives, however plumbing determines whether or not they transfer ahead.
Conventional drainage requires slicing slabs, rerouting pipe, and dealing round structural limitations. In older or occupied buildings, that strategy provides value, time, and danger.
Above-floor pump-assisted techniques change the equation by enabling installers so as to add moist areas — loos, kitchens, and laundry rooms — with out trenching slabs or disturbing historic finishes. A rest room, sink, or bathe might be put in virtually wherever with out the necessity for a jackhammer or noticed, permitting the unique construction to stay intact.
As an alternative of relying solely on gravity, these techniques use macerating or grinder pumps to course of waste and transfer it by small-diameter piping to the primary drain line.
For installers, which means:
- No slab penetration
- Much less structural influence
- Extra flexibility in fixture placement
- Quicker set up
In some circumstances, a system might be put in and operating in lower than a day.
How the techniques work and the place they slot in
Macerating, grinding, and drain pump techniques deal with wastewater by breaking down solids and pumping effluent vertically or horizontally to attach with the primary drain, eradicating the necessity for standard gravity circulation. This expands the vary of places the place plumbing might be put in inside a construction and helps each retrofit and new-construction purposes.
System configurations differ by scale.
- Single-unit techniques, resembling SFA Saniflo’s macerators, grinders, and drain pumps, can serve a full rest room, a kitchen sink, or a washer.
- At a bigger scale, light-commercial and multi-unit purposes use above-the-floor raise stations able to shifting as much as 250 gallons per minute, supporting a number of fixtures or whole flooring. In modular or multi-tenant buildings, particular person models usually pump to a shared central system.
Drain pumps are used particularly for grey water from sinks, showers, and home equipment when gravity drainage just isn’t possible. This makes it attainable so as to add fixtures on completed flooring, on higher ranges, or in places removed from present stacks. In retrofit initiatives, this strategy avoids routing new drainage piping by structural parts, a typical constraint.
In follow, these techniques are sometimes used for one-off additions the place new drainage strains are impractical.
Widespread purposes embrace:
- Full loos in areas not initially designed for plumbing
- Kitchen sinks in breakrooms or small residential models
- Laundry connections in closets or utility areas
By decoupling fixture placement from present stack places, they assist structure flexibility, significantly in adaptive reuse initiatives with various unit configurations.
Jobsite instance: Working round occupied area
At a 59,000-square-foot workplace conversion in Clearwater, Florida, the challenge known as for greater than 120 new loos whereas tenants remained in place. Wayne Cassity, proprietor of ABA Constructors Inc., and his crew had been tasked with remodeling a three-story workplace constructing right into a mixed-use residential and resort property with out disrupting occupants on the decrease flooring.
To accommodate the addition of over 120 loos—together with laundry and kitchen amenities—the builders applied a full above-floor plumbing technique utilizing Saniflo pump techniques with out having to chop by concrete slabs.
Every condominium unit is provided with a Sanibest Professional 1 HP pump system serving a bathroom, bathe, and toilet sink, all linked to a horizontal gravity drain put in alongside the hallway. Laundry setups use stacked washer-dryer models paired with a Sanicom 1 drain pump, whereas kitchen sinks discharge by a Saniswift Professional system.
This setup eradicated the necessity to reduce into the constructing’s structural concrete flooring, which might have been troublesome given the unique 1986 slab design. It additionally eradicated the necessity for disruptive evening work that would influence tenants. After a brief studying curve, installers accomplished every pump set up in about two days, serving to hold the challenge on schedule whereas limiting disruption and supporting a phased development strategy.

What contractors discover on the job
From an set up standpoint, the benefits turn out to be clear as soon as the work begins.
- Shorter set up occasions: No demolition or slab slicing required.
- Eliminates the necessity for coring concrete and trenching.
- Reduces the cleanup related to conventional drainage work.
- Can take away days from the challenge schedule and decrease commerce coordination.
- Better structure flexibility: Fixtures usually are not tied to an present stack.
- Permits contractors to observe design intent with out structural rework.
- Permits placement of loos, kitchens, and laundry areas the place they finest match the area.
- Lowered labor calls for: Much less reliance on heavy development work.
- Avoids intensive pipe rerouting and concrete-related duties.
- Retains crews targeted on set up moderately than demolition and restore.
- Simplifies execution and helps keep challenge timelines.
In occupied buildings, minimizing disruption is crucial. Above-floor techniques permit work to maneuver ahead with out shutting down operations, relocating tenants, or scheduling after-hours development. That may make an enormous distinction on initiatives the place components of the constructing stay in use.
Adaptive reuse initiatives proceed to develop, and contractors are searching for sensible methods to strategy them. Above-floor plumbing techniques permit work throughout the limits of present constructions whereas nonetheless delivering trendy plumbing.
As soon as contractors achieve expertise with these techniques, they carry that strategy into future retrofit work. It turns into a reliable choice when conventional strategies usually are not possible or would gradual the challenge down.
Regularly Requested Questions
Contractors not accustomed to above-floor plumbing will possible have questions. Listed here are a few of the extra frequent questions that SFA Saniflo’s technical consultants have answered:
Are these techniques momentary?
No. The expertise has been used because the Fifties and is designed for long-term use.
Will an SFA Saniflo pump meet head top and run limits?
These models are engineered for vertical raise and lengthy horizontal runs to succeed in a stack, principal, or septic line.
Is the system noisy?
Trendy techniques are quieter than conventional sewage ejectors.
Will it move code?
SFA Saniflo techniques are designed to assist code-compliant installations underneath each the Worldwide Plumbing Code (IPC) and the Uniform Plumbing Code (UPC), the place adopted. SFA Saniflo merchandise have been electrically and hydraulically examined by third-party laboratories, together with CSA and IAPMO, guaranteeing compliance with main plumbing requirements. As with all plumbing set up, contractors ought to confirm relevant state and native necessities and coordinate with the authority having jurisdiction to make sure full compliance.
