Will I still need a backflow preventer or does this unit have a built-in backflow preventer?

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.

It comes with a spray head that restricts the flow. If you use it as the instructions indicate you will not have a problem.

Hi Nicole, all of our breast pumps automatically come with backflow protectors.

Hi Robert, sorry it took so long to answer your request. I've been in the process of switching out computers and I had quite a few problems. First of all, we love our KOHLER shower head. I didn't know there was a restrictor in it. I just thought our water pressure was low. If you find that there is one in it, please let me know. Good luck. I never thought to call KOHLER and ask them.

came with it - it has a small water vapor discharge hose that goes inside the large exhaust hose. Last year it didn't seem to exhaust all water because I had a fair bit of water come out the bottom when I drained the unit.

Not this one...this is for the hose: this is the back flow prevention connector.

did not seem to reduce water pressure or flow, did not notice any restriction

Hey Mike I forgot to mention,I don't think they even sell them any more,the old aqua stop,would stop the water flow when you removed it,the newer style has the shut off and you are able to adjust the flow,as well,before you remove it.I'm at vportervint @aol.com if I can help answer,any other questions.

according to the box it's to prevent back flow. It will run just fine without it.

Reduced pressure backflow preventers are often used to prevent contamination of upstream potable water supplies. Some jurisdictions also allow double check detectors that are similar but don't require the drain. May want to check with your state health dept or plumbing code official with the city.

I installed the unit with a 3/4 " drain pipe directly to floor drain sump - so no overflow problems - the aprilaire 500 solenoid will only open when the unit detects that humidty needs to be increased - water will only run when the solenoid is open - there is no continuous water running at all like other units that do not use a solenoid water valve

It does have a backflow preventer.Am not familiar with CSA markings or where it would be located. Mine was purchased for residential use.

I have actually removed the nozzle guard gate altogether because 1) you don't need it 2) the guard actually makes the water splash all over. It works fine without the nozzle guard.

If would say put it above the timer. The first priority is too prevent backflow into a well or household pipes and second to protect the spigot and pipes from being damaged by freezing water. Your timers and hoses are not to worry about. Besides good rubber hoses shrug off a freeze. I put three of these siphon-breakers on early this spring and they have done the job through three frosts. I should add that backflow into a well or a municipal water supply can get you in serious trouble. Looking at the answer below,I have to admit that my experience is not based on an automatic valve -- it is based a manual spigot. So I'd listen to DougO in your situation.

The unit must be installed with flow following the arrow. It is directional. Do not install with flow going against arrow on unit.

Yes, you need tubing, an air stone or other device to create small bubbles and a check valve to prevent water from back flowing into the pump and ruining it.

No. The Orbit doesn't come with a backflow valve. You would have to install one at the faucet before the hose is connected. The door over the programmer seems to work very well. All of my Orbits are still working.
