backflow device for pool?

this may be a silly question, but do swimming pools need any sort of backflow device for their plumbing system?

That depends on your location and the applicable codes. If there is a shutoff at the house that feeds an underground line to a typical spout under the diving board, an atmospheric vacuum breaker would work effectively, assuming there is no secondary shutoff at the spout itself.

In our area (Houston Tx) backflows are required on all pools. I spot checked a couple of cities country wide and found they did also.

Some were very particular to type, some weren't. Need to call your local authorities.

re:

thanks! we just moved to an old, 15+ house with a pool so i was wondering if it was up to date and ready to go. we live in houston, so i'm guessing since backflow device is required, it's already got one.

Funny thing is I've seen pools with VERY small backflows. Don't know why.
Take a look around your pool pump and equipment.
If you had an inspection done on the house a licensed inspector would be required to tell you if you were missing one.

Enjoy the pool.

In my area- They are required.

And the fact that pools use chemicals a Reduced Pressure Back Flow Assembly is required because this is the highest form of protection

The spout under the diving board is already an air break, which is as good as it gets, and nothing else is needed, but the line between that spout and the potable water is looked at separately.
