Questions customers have been asking about this product:

I'm installing an in-line chlorinator, and the instructions say to use a "corrosion-resistant positive seal check valve" to prevent backflow of concentrated chlorine into the heater. Is this the proper valve? Are there others? I was hoping for the union check valve, but this appears to not have that. Also, I have 1.5" piping...the text says 1.5" and 2", but I don't see a way to order 1.5".

This would be the check valve they speak of in the owners manual for your chlorinator. This is the only check valve which is corrosion resistant and will hold up against the high concentration of chlorine near the chlorinator, unfortunately this check valve is only available without unions. Lastly this valve can accomodate 1.5" plumbing or 2" plumbing, if you have 1.5" plumbing your pipe will slip on the inside of the valve and if you have 2" plumbing your pipe will slip on the outside of the valve.
