Does it have the backflow protection

No. But, if you are concerned, you can disconnect it when finished; then reconnect your hose; then flush your hose. Otherwise you can install an anti-siphoning device.

Yes it does. You will find water flow is reduced when using this. I don't know if there are other items in the marketplace that does' affect water flow.

Yes, it does. The one thing about this unit to remember though is that you can't have, say, the waterfall AND the body sprayers on at the same time. It would just take too much pressure.

not sure exactly what you are calling the back. but if you blow air through the 1 of the spouts and open and close the valves the one that pass air when either valve is open is the spout port. I believe it was the middle one

No it does not. It's thick hard plastic. No metal protection or shock protection.

I don't use one. I just attach the hoses to the unit and set the timers. Have not had a back flow issue. Hope this helps you.

Yes. It is on the rear so it doesn't show in the photo. This evacuator is excellent by the way. I replaced a Mityvac with this and it is so much better than pumping it out by hand and trying to guess how much suction you had.

No this protects only the back. I didn't realize this upon purchasing the case and ended up buying a screen cover separately. Bummer

No it doesn't have a back cover. I haven't had a problem with hitting keys accidentally. This remote is a better design than my original slider remote. Great replacement...I recommend it!

No, but it does provide some water resistance protection. Mainly from splashes.

No it does not. It does have a black cover for protection. This wasn't mentioned in the ad, so we bought one. No need to do that.

Yes, it does. The silicon flaps don't cover the port completely, but it does do a nice job protecting it.

Look like you already got a couple of answers and I agree with them. This just connects as part of the hose to give you backflow protection but the threads are all the same as the hose threads.

There is no back flow on these, they are susceptible to cracking since they are only plastic. I go through one every 2 to 3 years.

To my knowledge this fixture does not have a backflow device. You do not need one on each fixture, your plumbing system should have one backflow preventer for the whole system.

The air intake are on both sides, not the back. It has a black plastic guard over them!

No it doesn't ,but the next model up "The Defender" does and offers another layer of protection.I hope this help.

Yes, it does, but it isn't leak-proof. It does not include a stopper. You have to install one yourself.
