My spa drains when the pool pump is off. Will adding or replacing one of these fix this?
Reply
Yes that very well may solve the issue. Per gravity, a raised spa will drian into the pool if the check valve is bad or if there is not one there.

My raised spa drains back to the pool when the pump is off. My question is where do I place the check valve at? Do I put it after the chlorinator (check valve being the last thing out) or do I install it between the heater and chlorinator (check valve being second to the last thing out) chlorinator being last thing out??

Cheryl, You will need to install the check valve after the chlorinator, the check valve should be the last thing on the return to the Spa.

will this check valve work with flex lines? What parts do I need to use this on a flex line operation.

Hi Jerry, Check valves are not recommended to use with flex pipe, you will need the use PVC for the check valve then connect the PVC to the check valve using a 2" slip x slip coupling. You can find such coupling at your local hardware store.

(5 out of 5 stars) No More DE on the Pool Floor
Reviewed By: Inyo Customer ()
I was always getting DE from my filter leaking back through the main drains and onto the pool floor. I put one of these between the filter and the pump and problem solved. Works great and easy to install.

(5 out of 5 stars) Made it easy to install an inline chlorinator
Reviewed By: Mark A. from Stafford, VA ()
Pros: Easy to install, sturdly built
Cons: Unsure about corrosion resistance to chlorine
I used this as a check valve to protect my pool heater from an in line chlorinator. It's not the one recommended by the manufacturer of the chlorinator(Rainbow), but theirs wasn't built with the screw on unions. This made it really easy to install the chlorinator, and will make any future repairs equally easy.
