Does this filter have an anti back flow mechanism, so oil won't drain back into the sump?

I want to say yes it did, been a couple months since I installed. No regrets, looks trick, reusable. Hope this helps.

No....it's a water hammer preventer. Need a check valve to prevent backflow

Yes Richard, I use it exclusively as a back-up. I have a generator & manual transfer switch, but that doesn't help if I'm away when my sump pump loses power. While it doesn't have the same through-put as my primary pump, it does a great job, even with a 9ft + head! Definitely happy with my purchase.

The valve they are referring to is the side mounted hi flow valve. (The one that says "Filter", "recirculate", "backwash"...etc). There are other models where there are no holes on the side and as such the plumbing and multi position high flow valve goes on the top....This is NOT that type of filter. So this ad means you get the pressure gage and air bleeder valve on top and not the side mounted multi position valve for "Filter", "recirculate", "backwash"...etc

Since buying the 530 I backwash less and my filter stays cleaner. I would say yes, cut that filter time.

No. It has an attachment that allows a hose to drain the unit into the sink or sump or wherever. It is gravity activated

Yes it does. I have mine connected to a sump pump but you can use it either way.

Yes it does, one for intake, one for outtake. And if you you don't use a pump filter like me, they supply plugs for the 2 holes.

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. Works well. Flow reduced by maybe 25% with water. Oil may be more do to viscosity.

It's the same principle as any air driven filter; the air pulls the water behind it. It's not a constant flow, the water comes out in spurts. There is also an option for an actual water pump.

It does, I found out the hard way. The company advertises no BACK siphons but it will definitely create a forward siphon.

Yes, there's a flow adjustment knob on the pump housing. You'll have to adjust it prior to placing the pump in the back sump. I have mine at the lowest setting and my betta swims around fine. You can also arrange decor or plants in front of the outlet to diminish flow further.

The drain plug is magnetic ,there is no need for a filter extension the extra fluid is more for cooling purposes. You might want to add transmission cooler also I did keeping your fluid cool is the life of any transmission especially if you have a high performance engine.

Sorry I did not buy this to drain oil, I use it to drain water off the top of my pool

Yes. It operates on a simple principle, pressure from the desired direction passes through while pressure from the opposite direction is blocked and will often activate a release causing "backflow" water to be drained off. Note: If, for example, a hose is attached that has a nozzle at the opposite end, that is closed, then the hose will pressurize and retain its pressure. If the faucet (with the back flow device installed) is turned off, the pressure will remain in the hose until the nozzle is slightly opened (or a connection is loosened) then the internal valve will release the hose pressure through the relief 'vents' in the back flow preventer. This device meets building requirements in many localities where a back flow preventer is required on outdoor water faucets. I use mine with an RV, so that water from the RV side does not enter the city water source side of the valve.

It has a check valve so that when the hose is disconnected, any water pressure in the inside line will not be released through the valve. This allows me to tee the external water source with the onboard pressure pump water line to the sink faucet in my camper. The fitting does not qualify as a backflow preventer for the water supply line since it is not equipped with an anti-siphon valve like those which should be either inherently built in to the hose bib or added on as an accessory before attaching the hose to the water source. Hope this helps.
