Does this pump have a built in anti siphon valve?

The pump does not come with checkvalve. You must buy that seperately. This will keep the water from flowing back down into the pit when the pump shuts off. You may be talking about a anti air lock hole. The pump does not have a hole drilled in it to allow air to escape. I drilled that hole myself and it prevents a air lock if the pump empties the pit and takes in some air.

No, you will need to install a check valve in the discharge line; something like Campbell Mfg Llc 1.5" Quietsump Chk Valve B-0823-15C. If you do a google search for Liberty Pumps 287, you will find the liberty pumps website and you can review the engineering specifications as well as installation instructions in PDF format. The installation instructions are printed and included with the pump.

No, it is just the connector and there was no shut off valve. That would be a nice feature though.

Yes it does. This switch is great. My well runs dry all the time and with this switch the pump is cut off automatically instead of continuing to run while dry

No it doesn't, I recommend getting the accessory float switch. The switch plugs into an outlet, then the pump plugs into the float switch.

I dunno what kind of valve access the board has, but the pump comes with several different size/type adaptors

The only thing I received was the rubber flapper backflow preventer. No separate true anti-siphon valve. I happen to have one on my faucet already.

It does not. The manufacturer recommends a pump with a flow rate of 20-40 GPH. Hope this helps.

Yes it does, one that runs off the airpump provided. A rather nice filter too

No it doesn't. If something gets into the water with the pump, it ends up in my tank.

No, but they do make a manual siphon pump that works very well. We received one free to try and it works so well that we realized that we could have bought the manual one instead. This battery operated one works well too but only attaches to non-threaded bottles.

Yes. Mine also had a 1 inch hose. I was aprehensive about choosing a replacement because my old pump was very noisy. This pump is excellent. I can stand next to it and still hear someone whispering. I have run it for only 3 months so time will tell as to longevity but so far I am very happy with the purchase.

No, it does not. However, it is a great unit. I bought one last year and it works a lot better than the Rule pump it replaced, and it's a lot quieter.

Yes, it comes with a Little Giant CV-10 screw in check valve to prevent water in the line from draining back down.

No, but the housing does a good job as a prefilter. It collects things >1/4". Everything else passes through the pump. I spray off the housing about once a month.

Yes it does. In the middle of the end. There is a plastic insert that fits in the hole and attaches to the pump inlet.

Thankfully, it does not! I've had several of the 'auto shut off' type pumps, and every one has been problematic. What I wanted when I purchased this pump was a proven, quality pump that, like the Timex, would just keep on ticking and not be troublesome at all. I have used this pump several times per week here in the rainy Northwest, and the pump has proven to be exceptional in all regards. It's rate of flow is very fast, and I'm using a 75' hose! I would recommend this pump most highly. Look no further...this is the one.

Yes. It's required by law to have an anti siphon device whenever hooked to a hose in case the water system looses pressure.
