does water flow from 2 inch to 1 1/2 inch side? Can water flow be reversed?

Hi Jim,The Jandy check valve (7235) is a directional check valve to only allow water flow to move in one direction. When the pump turns off, the springs shut the flapper to prevent the water from back siphoning. This valve can be plumbed with either 1-1/2" or 2" plumbing.Thanks for reaching out. If you have any additional questions, please contact our product support team at (800) 822-7933 or productsupport@zodiac.com and we will be happy to help you.Best,JulieZodiac

How do I measure to find the right size replacement flapper I need for my Jandy out door spa?

I would suggest you look up the model of your valve on line and then look in the Jandy parts list, online.

i have a 1 1/2 pvc line on either side would it work without the need to make reductions.

Hi Juany,Yes, this will connect outside of the 1 1/2 line. We hope this response was helpful! Please let us know if you have any other questions.Zodiac Pool SystemsManufacturer of Jandy, Polaris, and Zodiac products

What is the id for this valve (i.e what od of pipe would this valve slip over)?

Kevin, This Check valve is a 1.5"/2" port. This will take a 1.5 pvc pipe into the port or you can put a 2" coupler or 90 over the outside of the check valve.
