Does this perform as a check valve as well?

No, it only performs as a pressure regulator. You'll need to purchase a check valve in addition to this product. As far as this product goes, it works great.

This pump works so well, I just purchased another one. I am lifting water about 10 feet in a hose with no problem at all. I do recommend to install a check valve in the line if it will lifting water as I am. When the pump shuts off, any water in the hose will drain back if you don't have this check valve causing the pump to see water and start again. I'm replacing two Lowe's pumps that didn't last any time at all.

No check valves. I was also surprised to learn that the threads are British pipe threads, which is neat impossible to find in the US. It is, however, a quality product and maintains the set temperature.

Yes, it works great. I actually like using this over a battery operated pump. It is more reliable and works faster. You may just have to have someone hold it for you, because the valve could fall out. But it works great.

Hello Darshan, The Aquaus for Faucet does not include a check valve. The Aquaus for Toilet is the only product that requires a check valve and it includes two ASME Certified Backflows.

Sir: Yes this pump is a Sewage Pump made for that purpose. It works great and is very quiet, only sound I here when in my basement is the sound of the Check Valve closing.

After a second look, it does have a reilef valve. And it works as it's supposed to.

Yes, gas will not flow unless another fitting is hooked up to it, just like the fitting on the new style tanks. It is not a "check valve" or "one way valve" though, as gas can flow either way.

I see no reason for it not to work under water. I own (2) of these and have install quite a few more.Very well made 1 way check valve.

There's no check valve but I've never experienced a problem with starting waterflow or maintaining it. By the way, this pump is probably best use for tanks 55 gallons or less.

Yes, the 99555 is a check valve that would keep the drain hose from running back wards when you shut your V pump off. I don't know if the threads will fit though, you might have to either just clamp it in to be water tight or purchase other fittings to get it the correct size. Based on my experience with this check valve (I posted it), I would not use this to keep an important location from flooding.

It depends on where you have the check valve installed. If you have it inline after both pumps meet, then no you don't. If your check valve is attached to the main pump, then yes you would need another check valve.

my previous post about check valve, might be in pump internally and not separate unit

I have not fired it up yet, but yes, it will. It is a centrifugal pump, and without some sort of check valve, this type allow bypass flow in the off state How much depends on the internal clearances, viscosity, and back pressure.Hope this helps.

Yes. This device is a heavy duty, full flow one. It is more expensive that the lower quality model, but well worth the extra cost. The cheaper models tend to have the discharge necks snap off after little use. This model has experienced no such defect. I have two installed - both replaced the cheaper model.

- No check valve included (cannot recommend one as I just installed the pump into the existing circuit)- I don't think this is the correct pump for an irrigation system- We use if for our house water and it definitely needs to be used with a pressure tank

I didn't buy the check valve for a pump such as you appear to be using. What is the purpose of the pump and why are you concerned about back-flow or back-flush?
