Why Commercial Pool Operators Are Choosing Stainless Steel MainDrains

When people think about commercial pool construction, they usually focus on the visible
features – tile finishes, lighting, decking, or water attractions. But some of the most
important decisions happen below the surface, especially when it comes to main drains.
According to Paddock Pool Equipment leadership, choosing the right main drain system
can dramatically impact installation efficiency, long term durability, maintenance costs,
and future code compliance.
Why main Drain Selection is Often Overlooked
One of the biggest challenges in commercial pool construction is that owners are rarely
the sole decision makers. Architects, consultants, builders, suppliers, and engineers all
influence equipment selection. In many cases, initial cost becomes the driving factor
instead of long-term performance.
That short term mind set can lead facilities toward lower cost materials that may require
expensive repairs or replacements later.
As Paddock’s COO explained, not everyone involved in the process is thinking about
the full lifespan of the pool.
Stainless Steel Maindrains Simplifies Installation
Commercial contractors are increasingly turning to stainless steel main drains because
they make installation easier and more reliable. Unlike fiberglass systems, stainless steel main drains can be tied directly to rebar or mechanically attached to the preform pad. Their rigid structure and added weight allows crews to properly vibrate concrete during installation without risks or cracks or
damage. Fiberglass systems often require additional pours, water stops, and extra labor.
Installers also face the risk of drains floating, cracking, or collapsing during concrete
placement.
The results for turning to stainless?
Faster installation
Fewer concrete pours
Reduced labor costs
Safer installation conditions
Fewer opportunities for installation failure
Contractors do report labor savings and smoother project execution with stainless steel
systems.
Fewer Repairs and Callbacks
Durability matters – especially in commercial aquatics where downtime can be
extremely expensive. Facilities using stainless steel main drains often experience fewer callbacks and
corrective repairs because the systems are built to withstand harsh pool environments
for decades.
Fiberglass and plastic components are vulnerable to:
Chemical degradation
UV exposure
Heat damage
Structural weakening over time
Stainless steel eliminates these concerns.
According to Paddock, their goal is to build products that should not need replacement
during the life of the pool itself.
Long-Term Compliance Matters
Commercial pools face annual inspections and evolving safety standards. Main drain
systems that fail inspections can trigger expensive reconstruction projects.
Plastic and fiberglass drain covers often require frequent replacement to remain
compliant. Stainless steel systems, however, provide superior structural integrity and
long term compliance. Paddock was also the first compliant manufacturer following the Virginia Graem Baker Act (VGB Act) – reinforcing the company’s focus on long term safety and compliance.
The Real Cost of Choosing Cheap Materials
The initial purchase price of stainless steel may be higher, but lifecycle cost tells a
different story. Replacing a failed main drain system can cost anywhere from $5,000 to $30,000
depending on the extent of demolition and reconstruction required.
Facilities may need to:
Cut out concrete
Rebuild structural sections
Replace plumbing
Shut down operations for extended periods
By comparison, stainless steel systems can realistically last 30+ years.
And according to Paddock’s experience, many facility operators who initially chose
cheaper materials later regret not investing in stainless steel from the beginning.
The Bottom Line
As regulations evolve and facilities seek longer lasting infrastructure, stainless steel
main drains are increasingly viewed as the safest long-term investment.
When asked what advice he would give pool designers and operators, Paddock’s COO
answered simply:
“Why not stainless?”
