Replacement Key Considerations
Drain covers must be sized to handle the highest possible flow rate for the specific pump and system - not the flow rate the pump is expected to operate at most of the time. A pump’s highest potential flow rate is found at the end of the model’s specific performance curve, it’s important to select a cover with a higher flow rating.
Pump Performance Curve Chart
Hazard: Pump flow rates higher than the cover’s rating can increase the risk of hair entrapment and cause dangerous suction levels.
Solution: Choose a cover with a higher flow rate than the maximum flow potential of the pump.
NOTICE: Pump flow potential is best determined by measuring flow or measuring the TDH of the system during high-speed, clean-filter operation and then looking up the actual flow using the manufacturer’s published pump curve. To avoid oversizing drain covers and suction piping, the use of a flow meter or the TDH measurement method is suggested for pumps larger than 3 HP.
Sump depth is the distance between the underside of a drain cover or grate and the suction pipe opening. If you find that a drain is installed with an incorrect sump depth, replacing it with a sumpless cover is a great solution.
Hazard: If the sump depth is too shallow, it may cause hair to twist and tangle around the cover.
Solution: Check the sump prior to selecting a cover. If insufficient, increase the sump depth to match the cover’s requirement or choose a cover rated for zero sump depth installations.

Why is replacement a priority?
IT'S THE LAW. The VGB law that went into effect in 2008 requires that all public pools and spas have drain covers that comply with the ASME/ ANSI Al 12.19.8 performance standard, or any successor standard, currently ANSI/ APSP 16- 2011. This standard requires that manufacturers determine a life expectancy and place a permanent mark with “Life: X Years”; on each cover to indicate service life lifespan. At AquaStar, based on UV, structural and fastener testing, we’ve determined that our drain covers should be replaced every five years or ten years from the date of installation, as stated in our instructions. We have partnered with you to make sure your customers are in compliance with following the law and our customer service department is here to help in any way we can.
REDUCE LIABILITY. The law requires that compliant drain covers be installed in all public pools and spas, in accordance with manufacturer instructions. Failure to comply can result in pool closings and stiff civil penalties, as well as resulting liability in the event of a tragedy.
IT'S SIMPLE. Public pools are required to install compliant covers in accordance with manufacturer instructions. You want your residential customers to have the same level of protection. To ensure structural integrity and avoid accidents with broken covers, the drain covers that public pools and spas installed five years ago need to be replaced. Our drain cover solutions give you the selection you need to meet any requirements. See our replacement Cross-Reference Chart (page 17), Visual VGB Suction Outlet Replacement Guide (page 18-23), or our mobile phone friendly Drain Cover Replacement Guide on www.aquastarpoolproducts.com to view our wide array of available replacement options. If you don’t currently have an AquaStar drain cover, we also have many retro-fit choices that will adapt to other manufacturers frames and sumps. Keep in mind that you must also assess the integrity of the existing frame or sump to ensure that it is structurally sound and able to get three threads of engagement with the new screws provided with each cover. Remember, at AquaStar, every product is held to the highest standard of quality, resulting in superior, dependable products that last.
IT'S SMART BUSINESS. When you remind your customers about their upcoming drain cover expirations, you are more than just a pool supply vendor for them. You're a trusted resource and partner helping them stay compliant with the law and keeping consumers safe. And that's good for business.
DON'T WAIT UNTIL IT'S TOO LATE. While replacing drain covers is the legal thing to do, it's also the safe thing to do. Help your customers make the right decision - at the right time.
General Replacement Questions
Do drain covers have an expiration date?
Yes. The VGB law that went into effect in 2008 requires that all public pools and spas have drain covers that comply with the ASME/ANSI A112.19.8 performance standard, or any successor standard, currently ANSI/APSP 16-2011.
This standard requires that manufacturers determine a life expectancy and place a permanent mark with “Life: X Years” on each cover to indicate lifespan. At AquaStar, based on UV, structural and fastener testing, we’ve determined that our drain covers should be replaced every five years from the date of installation, as stated in our instructions.
Any drain cover that is broken or missing should be immediately replaced before swimmers are allowed in the pool.
Our Certificate of Compliance provides space to keep track of drain cover expiration. Please fill out and safely store this document, it may be requested during inspection processes.
When replacing a drain cover does the mud frame/sump need to be replaced too?
The existing frame/sump must be in good condition, or else it must be replaced.
The drain cover's screws must securely fasten to the frame and have a minimum of three threads of engagement.
Where can I find the manufacturing date for the suction outlet cover?
The manufacture date is molded on to each drain cover, it is represented by a small dial that has the year in the center and an arrow pointing to the month.
Drain cover expiration is not based off the date of manufacture, but when the product is installed.
