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 1836xxx have an expiration date?
Our 1836xxx drain covers are manufactured with a strong PVC material and have a 10 year life-span.
Will the 1836xxx replace any other manufacturer drain covers?
The 1836xxx is intended for new installations and is not recommended to be used to replace other manufacture 18'' x 36'' drain covers. For 18'' x 36'' replacements please refer to AquaStar model # R1836xxx (xxx = Color Code).
When the cover for the 1836xxx 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 1836xxx 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.
Why do some areas require builders to split single-unblockable drain covers?
A small percentage of states and regions have not adopted the most recent codes and standards that allow the use of single-unblockable drains. Only one VGB unblockable drain is required to comply with the VGB Pool & Spa Safety Act, International Swimming Pool and Spa Code (ISPSC), ANSI/APSP/ICC-5 residential pool standard, and ANSI/APSP/ICC 7 (2006 & 2013), provided the flow rating engraved on the cover equals or exceeds the maximum flow rate of the specific system. California, Texas, Arizona and several other states have adopted the ISPSC as an optional building and remodeling code that allows single-unblockable installations.
