Product Specific FAQ

Click on a question to see the answer. If you do not see your question below scroll down to the bottom to send us your question. 

Does the R18MFNFxxx 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. Please look above under ''Support Documents'' to download a Certificate of Compliance for this product. Please fill out and safely store this document, it may be requested during inspection processes.

Will the R18MFNFxxx replace any other manufacturer drain covers?

Yes, we manufacture different versions of this grate to fit both 3/4'' and 1'' deep mudframes.

Pentair frames are typically 3/4'' deep and Hayward frames are typically 1'' deep

If you need just the cover and hardware for a 1'' mudframe use part number R18MFNFxxx.

When the cover for the R18MFNFxxx expires, do I need to replace the mudframe/sump too?

The existing frame/sump must be in good condition, or else it must be replaced.

The new 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 R18MFNFxxx 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.
