A&a Manufacturing Pool
The swimming pool equipment term a&a manufacturing pool refers to industry-leading hydraulic in-floor cleaning and circulation systems engineered by A&A Manufacturing (now a premier division of Pentair Commercial Pool). Designed to eliminate unsightly automatic robotic vacuums and tangled floating hoses, A&A in-floor systems utilize flush-mounted rotating pop-up cleaning heads installed across the pool floor, steps, and benches. Driven by a non-electric water distribution actuator valve, these systems sweep dirt and debris toward the main drain while circulating heat and chemicals evenly. Exploring system mechanics, valve maintenance, nozzle replacement, and troubleshooting guarantees crystal-clear water with minimal effort.
Hydraulic In-Floor Cleaning Physics and Water Distribution Valves
The engineering brilliance of an a&a manufacturing pool system lies in its entirely hydraulic, water-powered operation. As pool water is pumped from the filtration system, it enters the A&A water distribution valve (popularly known as the Top Feed or Low Profile valve). This cylindrical valve houses an internal impeller and a heavy-duty gear assembly that rotates a sequential cam plate. Unlike automated electrical valves, this mechanism is powered entirely by the pressurized flow of filtered water.
As the internal cam rotates, it systematically opens and closes five or six distinct port zones. Each port directs high-pressure water through underground PVC plumbing lines to a specific cluster of pop-up cleaning heads on the pool floor. As water pressure surges through the zone, spring-loaded nozzles pop up from the plaster floor, spraying a concentrated, fan-shaped water jet along the bottom that pushes settled sand, dirt, and leaves toward the deep-end main drain basin.
Review the primary components and operational functions of A&A in-floor pool systems:
| A&A System Component | Operating Mechanism | Functional Pool Role | Maintenance Requirement |
|---|---|---|---|
| Water Distribution Valve | Water-driven gear cam mechanism | Rotates flow sequentially across 5-6 zones | Inspect gears & T-valves annually for wear |
| QuikClean Pop-Up Heads | Hydraulic pop-up with internal ratchets | Sprays high-velocity jet; rotates 30° per cycle | Remove with installation tool to clear pebbles |
| Low-Profile Water Actuator | Compact top-feed valve body | Manages high flow rates up to 80 GPM | Lubricate center O-ring; check acrylic ball seals |
| Puddle Flapper T-Valves | Internal rubber/plastic flapper plates | Seals non-active zones to build pressure | Replace worn flapper discs if heads stay up |
| Debris Removal Drain (PVR) | High-flow vortex suction main drain | Pulls swept debris into filtration basket | Ensure VGB-compliant anti-entrapment cover |
Thermal Circulation, Chemical Efficiency, and Energy Savings
While primarily marketed as an automatic cleaning system, an a&a manufacturing pool installation delivers profound thermal and chemical advantages. In traditional pools with surface wall returns, hot water from pool heaters and fresh chlorine from chlorinators are injected directly onto the water surface. Solar heat and wind rapidly evaporate these chemicals, creating a hot surface layer while bottom waters remain frigid, inviting algae blooms on deep plaster floors.
Because A&A in-floor heads inject water directly at the pool floor, heated and chlorinated water is forced upward from the very bottom of the vessel. This bottom-up convective circulation eliminates cold pockets, reduces heater runtimes by up to 30 percent, and prevents localized chemical depletion. Furthermore, circulating warm water through the bottom prevents thermal stratification, keeping entire swimming pools evenly heated and reducing overall chemical consumption by up to 50 percent.
Troubleshoot common A&A in-floor cleaning system malfunctions:
| Symptom / Failure | Underlying Mechanical Cause | Pool Impact | Recommended Corrective Action |
|---|---|---|---|
| Pop-Up Heads Won't Pop Up | Low pump pressure or dirty filter | Zero floor cleaning action | Clean/backwash pool filter; check pump impeller |
| Heads Stay Up and Don't Retract | Sand/pebbles jamming nozzle sleeve | Obstacle hazard for swimmers | Extract nozzle with A&A tool; flush out grit |
| Heads Pop Up but Don't Rotate | Broken internal ratchet teeth in head | Cleans only one static narrow strip | Replace internal pop-up nozzle mechanism |
| Valve Stays Stuck on One Zone | Stripped gear train or broken valve cam | Only one zone fires continuously | Install A&A 5-port or 6-port gear replacement kit |
| Water Leaking from Valve Lid | Cracked valve clamp band or dry O-ring | Water loss and suction air leaks | Lube lid O-ring with silicone; replace clamp band |
Rebuilding the Water Valve and Clearing Jammed Pop-Up Heads
Routine maintenance of an A&A in-floor cleaning system centers on two straightforward procedures: servicing the water valve and clearing jammed pop-up nozzles. Over three to five years of continuous operation, pool chemicals and fine plaster grit can wear down the internal plastic gears in the distribution valve. Rebuilding the valve takes less than fifteen minutes using an A&A complete gear kit, which drops directly into the valve housing without cutting plumbing lines.
If a pop-up head fails to retract flush into the pool floor, tiny pebbles or plaster chips are usually wedged between the nozzle casing and the outer collar. Using an A&A specialized three-prong removal tool attached to a standard pool extension pole, technicians twist the head a quarter-turn counterclockwise to unlock the bayonet tabs. Once removed, rinse the nozzle in fresh water, lubricate the spring, and snap it back into place.
How to Rebuild an A&A Water Distribution Valve Gear Assembly
Follow these five steps to replace worn gears in an A&A in-floor water distribution valve.
Shut Down Pool Pump and Bleed Filter Pressure
Turn off the main pool pump circuit breaker and open the air relief valve atop the filter tank to release all water pressure.
Remove the Center Band Clamp Around Valve Lid
Use a 7/16-inch socket or nut driver to loosen the stainless steel clamp holding the clear acrylic or dome lid to the valve body.
Extract the Worn Gear Plate and Cam Assembly
Lift the dome lid off and pull the old plastic gear plate, impeller, and T-valves straight out of the circular valve base.
Inspect Valve Ports and Seat the New Gear Kit
Clean sand from the bottom ports, apply silicone grease to the center shaft, and drop the new factory A&A gear kit into the alignment slots.
Lubricate Lid O-Ring and Re-Torque Clamp Band
Coat the rubber lid O-ring with silicone lubricant, seat the dome lid, tighten the clamp band securely, and restart the pump.
Frequently Asked Questions (8 Questions Answered)
Q1: What is an a&a manufacturing pool system?
It is a hydraulic in-floor pool cleaning and circulation system that uses rotating pop-up floor jets to sweep debris and circulate water.
Q2: How does the A&A water distribution valve work without electricity?
The valve is powered purely by water pressure; incoming water spins an internal turbine impeller connected to gears that cycle through ports.
Q3: Why do A&A pop-up heads get stuck in the up position?
Sand, small pebbles, or calcium scale get lodged between the rotating nozzle sleeve and outer collar, preventing spring retraction.
Q4: How do you remove an A&A pop-up head from the pool floor?
Attach an A&A specialized plastic removal tool to your telescoping pool pole, align the prongs, twist a quarter-turn counterclockwise, and lift.
Q5: How often does an A&A water valve gear kit need replacement?
The internal gear assembly typically lasts 3 to 7 years depending on filter cleanliness, pump operating pressure, and chemical balance.
Q6: Do in-floor cleaning systems save on heating costs?
Yes, by returning heated water to the floor instead of the surface, in-floor systems eliminate cold spots and reduce heating costs by up to 30%.
Q7: What is the difference between a 5-port and 6-port A&A valve?
A 5-port valve controls five independent floor cleaning zones, while a 6-port valve manages six zones for larger pools and spas.
Q8: Can an A&A in-floor system clean fine silt and leaves?
Yes, the high-pressure rotating jets sweep fine sand, dust, and leaves toward the main drain basin where the filtration system collects them.
