Cobra Products 650 Air Drain Blaster

• Clears household drains with a burst of air
• 4 Drain Size attachments
• Strong poly construction

I own a 100-year-old four-plex in New Orleans, so I spend a lot of time dealing with slow drains. The Drain Blaster is the first product I reach for now and it always gets the drains moving. Sometimes I have to supplement later by using the Drain King Drain Flusher (G. T. Water Prod. 186 Drain King Drain Opener)in the clean-out, but the Drain Blaster always at least gets the water moving and, in doing so, ends the emergency.

In the video I tried to present a fair overview of the Drain Blaster's strengths as well as it's limitations. I hope it helps you make an informed decision. I have more on this product and some pretty effective other drain clearing tools on my website.

The clear p-trap shown in the video is the PermaFlow Replacement Drain. PermaFLOW Never-Clog Drain

Update 02-27-2011

This Drain Blaster stopped working after about eight months of use. The seals seem to eventually begin to slip out of place inside the main chamber causing it to lose pressure. With a single-piece plastic housing, you can't open it to repair or replace the seals. When the seals go, the device goes... into the trash. I wish they made a product like this in metal, it would be worth the extra money to have a tool that could be repaired.

There is a professional version of this tool made from aluminum and stainless steel, with pressure gauge it goes for over $200. This plastic version does what the pro version does at around 1/10th the price.

A few tips: 1) make sure there is water in the drain over the drain opening (It is not the air blast that opens the drain, it is the air blast pushing the water column that opens the drain)

2)Don't be afraid to repeat the process 8 -10 times or more it will work eventually.

3) Most of the negative reviews are due to operator error. They say "I pumped it twenty times..." the instructions say "pump 20 -30 times" give it the full 30 if lower pressure blasts don't work first, and make sure they are full strokes (the plunger gets quite stiff as you keep pumping, I'd guess the last few pumps take over 60 pounds pressure on the handle)

4) When you position the blaster in the drain and pull the trigger, you really have to lean on the handle, you want all the force pushing down into the drain, not pushing the blaster up and away.

Had I bought this first I would have saved $100 or so that I wasted on other products.

I had a stopped bathtub drain that would not clear up with a shop vac, Turbo Snake, plunger, Cobra Zip-It, and a traditional plumber's snake.

This was my last attempt before calling the plumber and it worked perfectly on the fourth try and the drain is now flowing better than it ever has.

IMPORTANT NOTE: I would NOT use this on a drain that has been recently treated with Draino (lye based) or Acid based drain openers because it will get everywhere and you will get burned. I would also wear saftey goggles in case debris come flying back at you.

On the first attempt I plugged up the tub's overflow hole with a wet rag and hit the drain with the Drain Buster 650 (20 pumps). The wet rag that was stuffed into the overflow shot out across the tub and water shot about ten feet hitting the window of my bathroom.

On the second attempt I held the wet rag in place with one hand and used my other hand to pull the trigger of the Drain Buster 650 (20 pumps). I heard some gurgling in the drain and knew I was on the right path.

The third try was done using 25 pumps and the water started to drain.

The fourth try was done with 30 pumps and the water was rushing down the drain.

I really love this product. It turned a nightmare of a clogged drain into a smooth operator. I would recommend this to anyone that is having problems with slow or stopped up drains.

Bought this cause my bathtub gets stopped now and then. Actually seemed to be working well, my clogs were gone, come to find out, that the air pressure was too much for my older plumbing and ruptured my pipes. This caused way more damage and money than the cost of buying this to unstop my drains. So if your clog seems to have vanished, check your pipes, they may be gone.

This blaster worked like a champ on my clogged sink. It took 3 blasts to get things going, but that was mainly because I didn't follow the directions the first two times.

With the first blast, I didn't have any water in the pipe; so of course, nothing happened as the blaster merely puffed air into the open air space. I reviewed the directions and found my error, and filled the drain with water, plus enough to cover the blaster's adapter.

The second blast was comical. Being underwhelmed with the muffled PFFT from the first blast I held the blaster in place with one hand and pulled the trigger. My wife and I were splattered with water, as were the surrounding walls. That's when I fully realized this thing produces a small air explosion! So be forewarned. If you've used any caustic chemicals on that clog prior to trying this blaster you better make sure they've all been flushed out of the system. If there's any doubt, I would definitely use goggles and gloves, as the directions recommend.

For the third shot I really leaned into it to make sure none of the pressure would be released out the sides. Boom! The clog cleared.

This product requires a bit of strength. So I'd say it's probably not something to buy for your elderly grandmother to help around her house.
