does the pump have a built in regulater so it can shut off automatically when it reaches a certain pressure ?

Do you mean if the inlet pressure is sufficient then the booster pump would cutoff? I do not think so because the pump would need a bypass if this was the case and I have not seen such. Without a bypass the pump would limit water flow so you would not have the pressure at the necessary flow rate with the pump not running. the purpose of the booster pump is to make sure their is sufficent pressure with sufficient fo to run the polaris so it cleans effectively. If your system has enough pressure without it it you dont need one, btu if you need one you need it all the time, if you want your pool clean that is.

To expand on the answers given, no it does not. It seems your comment describes a shallow well pump. What this really needs is a no flow cut-off, so it can cut off if it loses prime due to low water levels or broken pipes. However, for what it is suppose to do, I give it an A+ rating. I've used it two years now to power my Polaris 280 without any troubles.

The previous answers are all correct. The pump would require a bypass on the volute chamber or voluth if you prefer. Another possible shut of would be a pressure sensor that would release a motor contact set and there is not anything resembling these two things on this pump. However, if you need the pressure to not exceed a set point any one of these two options could be added to the pump. NOTE: all Polaris system use a pressure relief device located at the connection at the pool side. This is where the hose connects from the outlet to the Polaris unit. If the pressure gets to high it blows a disk off and the back pressure is released. The previous answers are all correct.

I thought there was one in the box when it came. However it is relatively uncomplicated and I had it figured out in a day or two. Just remember it does not have an automatic shutoff.

No, it has the pressure guage and the single "on" when you plug it in ... There is no way to control the pressure output.

There is no auto pressure release valve to my knowledge.. I know this because if it doesnt start after the second or third pull you MUST release the pressure in the line ( trigger to release pressure or pump lock-up). Having said this the unit does have a variable pressure valve -100 PSI up to 3100 PSI- which I always turn down the pressure before shutting down ( aids with re-start). I do not believe the unit has a pump over heat protection circuit.. I shut the unit down if I am going to have it sit more than a two minutes ( engine running) without pump pressure release. Quite honestly I purchased this unit for the variable pressure feature.. I am quite satisfied with this unit... though other Generac equipment I own (generator) has been very problematic.... cheap Chinese engine and carb... Generac would be wise to use solid name brand engines like Honda, B&S, Yamaha.

No, this is not an automatic pump. It requires manual and or float switching to opetate correctly.

Yes it does and is it also has the option for intermittent spray every 30 seconds. When the water runs too low it shuts off automatically

Yes, it will shut off automatically when it runs out of water, even with power connected.

No, it does not have an automatic shut off. You must turn it off manually.However, it does work really well.

The pump will build pressure in the system untill you shut it off or the pressure regulater if you have one in your system shuts it off. A pressure relief valve installed in the system will insure the system will not rupture.

This pump does not have automatic shut off. It runs continuously until turned off or unplugged.

there is not an automatic shut off. You do have the option of turning it on so that the machine runs for 1 minute and is off for 1 minute, or something like that. I'm not exactly sure of how long the on/off time is, but it's quite sshort. There is a clear raised line inside the water reservoir for the max fill line. Sort of reminds me of the clear raised lines on the clear caps of liquid laundry detergent. I either take it in the bathroom to fill where there is good light, or I only fill it half full. If it is empty, it will not run.

Yes it has a little sensor that shuts off the unit when the water level falls below it.
1329711
Yes. Mine turns off automatically if I have the water running for a long time. I actually like this feature. It does save water.

Yes, the unit has a built in shut off function when the water level gets low. However the jug only fills about 3 quarters of the way up before shutting off in about 5 hours. Best set it and forget it unit I've seen worth the investment.

Yes, it does have a regulator. It has two guages right on top, one for tank pressure and the other for output pressure. It has a dial to raise or lower the output pressure. Hope this helps

I agree with Marlowe. The pump can't be regulated, however I put an inline regulator in my system. Pretty simple fix to regulate max pressure.

Yes this pump has a pressure switch and will begin pumping when faucet is turned on and then stops when turned off.
