Can I purchase 10 foot sections instead of 5 foot sections?

A  Answered on 2/10/2012 by InyoPools Product Specialist Patrick P.

Typically these come in 10FT sections from the manufacturer but we have them cut into 5FT sections so that we can ship them via UPS instead of freight truck. This saves the customer a great deal in shipping costs.

Do you include these additional couplers since you cut the product, or is this something that needs to be ordered in addition?

A  Answered on 9/2/2014 by InyoPools Product Specialist Patrick P.

The couplers to join the two 5" sections to make the 10" are included.

Is this system suppose to be flush with the deck when finished or lower. Is there a photo of what a section of this will look like after installation?

A  Answered on 5/26/2018 by InyoPools Product Specialist Lennox H.

Hi, Debra. It should be flushed or lower than your deck once installation is completed. The deck should be sloped allowing water to drain to the deck drain.
