GENERAL FIT ALL BACK WATER 2"
From the Manufacturer
General Pipe Cleaners Flood-Guard Prevents Basement Flooding. Flood-Guard operates like a check valve to seal off water back-up caused by overloaded sewers. Water flows normally through the drain until the sewer begins to back up. Then the Flood-Guard float rises to seal off the drain opening until the water recedes.

It does what it says! No more overflow in my laundry room. My drain is old so it does not seal perfectly, but I do not have a puddle when I do laundry anymore.

I will update this as time progresses (once the product is tested). I have a stream in my front yard and an ancient floor drain in my basement drains to it. Stream goes up, so does water in my basement.I installed in an old cast iron 2" floor drain. FYI if you have this type of drain..... Mine is exactly 2" inside diameter. This unit has a pretty much exactly the same OD. It was so tight i had to try and rasp down any high areas in the pipe, but it was still too tight. I ended up taking off just a few thousandths from the lower aluminum ring and it fit perfect. Not a big deal but for those of you with an old drain, if you do not have tools to do this, be aware it COULD happen. It would probably fit fine in a new drain, but if you have an ancient one, expect the diameter could have reduced over time due to corrosion.

Bought this backflow preventer 5 years ago. We have a floor drain for our kitchen ice maker which connects to a common drain line for two kitchen sinks and the dishwasher. When the common drain line clogs, water backs up out of the ice maker floor drain. I installed this backflow preventer to stop that from happening. Today we had a repeat flood event with water coming up throgh the backflow preventer. How did it fail and why do I say its guaranteed to fail? The design relies on a stainless steel pin that slides through an aluminum frame. Think of it as a bearing surface. If anything stops the pin from sliding the valve cant shut and the backflow preventer cant to its job.. When stainless and aluminum are immersed in water it results in galvanic corrosion turning the aluminum into aluminum oxide which is physically larger than aluminum. So the aluminum corrodes and swells and the pin can't slide throught the aluminum anymore. The valve is stuck open. Had they used the same alloy stainless steel for the frame all would be good. Note I own a number of boats used on salt water so I am no stranger to the problem of galvanic corrosion between dissimalar metals. Bottom line? Either replace this valve regularly or look for a more reliable solution. I am currently looking for a more reliable solution, if you have one please respond.

Basement drain without much slope, floor flooding regularly. Installed the flood guard and "voila," no more backing up onto my floor. I have no idea how effective it would be for big backups, but it has eliminated the 16-20 ounces I was seeing on a fairly regularly basis entirely.I did take the advice of another reviewer and purchased hex head screws to replace the ones included, which made it much easier to install because I didn't have to press down. Basically, the screws collapse the area between the two metal parts and expand the rubber to fill the drain. Until you do that, it just slips up and down in the 2" drain. Once installed, the mechanism is simple. An upside down cup slides up and down based on whether water is coming up the drain, closing off the drain to prevent backflow.It's been about a month, but no problems so far and I it works exactly as advertised. Also, it was also so cheap that if it ever stops functioning, I'll probably buy another.Update, 16 October 2016: stopped working and I took it out to figure out why. The valve, which is really just a piece of stainless steel running through a stainless steel hole, was frozen. I lubed it up with silicone grease, but it didn't loosen up enough for me to feel comfortable. We shall see...

I had a few plumbers in to give me bids on a installing a back flow prevention device on my city sewer line. The first plumber quoted $1,100. The second plumber quoted $2,300. The third plumber said, "All you need is a Flood-Guard. I can put one in for you for $40 or you can do it yourself."I took the advice of Plumber #3 and will be sure to call this incredibly honest plumber for any future plumbing needs.This was very easy to install in my basement floor drain. It took all of ten minutes.There is one thing to be aware of. I flush a two gallon bucket of water from my water heater once a month to remove any junk that's collected at the bottom of the tank. I pour the bucket of water down the floor drain. With the Flood-Guard installed in the floor drain, I have to pour the bucket of water down the drain a little slower than I used to. There's absolutely no problem with drainage from my humidifier, A/C and high efficiency furnace condensation runoff, as those are each just a trickle.

Excellent to prevent back up flow of water from the shower drain when I drained the water from the bath tub. Works perfectly.

Stopped our recurrent backflow problems immediately. Can now shower in basement without water from kitchen sink coming up through drain! Very easy to fit and well priced. Only wish I had known it was available before.
