CobraProducts 331 Drain SMALL BLADDER, No Size, No Color

I went through several different attempts of cleaning out the line from my kitchen. It does allow access from an outside wall behind the kitchen. I tried chemicals, a 25 foot hand snake, pressure washer directly in the pipe for 15 minutes, none of these worked. Came across this wonderful device, had it in hand 2 days later and it worked perfectly. I’ve since been using it every 3 months as preventative maintenance to avoid any further blockages. 1/200th the cost of a plumber.

Bought this a while ago. Put it to use yesterday. Wow. This really works great. Slow draining sink now sucks down water. Amazing. Highly recommended. Tips for use... 1) Buy this size for vanity sinks (sink you brush teeth in, etc.) 2) Get standard garden hose. 3) Get faucet adapter with male thread for faucet and male thread for hose (such as NEOPERL 571493 at Home Depot.. if your faucet is smaller ID thread, you may need different part number). Getting faucet adapter is critical for success if you are supplying water from inside house. If not, run a hose from outside spigot into house, but this is more difficult and should involve two people since you should slowly turn on water supply and make sure drain cleaning bladder remains fixed in drain pipe. 4) If faucet aerator removed to install faucet adapter has buildup on it from water deposits, put it in a cup with vinegar for 30 minutes or so to remove deposits before reinstalling. 5) Before inserting drain cleaing bladder in drain pipe, remove sink drain stopper lever assembly below sink in drain line (probably need to do this to remove sink drain stopper anyway). Leave out when purging drain line, making sure drain cleaning bladder covers open hole (because if not, water may come out during unclogging process). 6) If you see lots of hair / gunk in drain that can be removed by hand, remove it wearing thin plastic gloves and throw it away... forcing down the drain might work, but probably not a good idea. 7) Slowly open COLD water supply (do not use hot water supply) and let drain cleaning bladder do what it is designed to do, letting it run for a few minutes to fully flush line and push everything down stream. I was amazed at how well this worked. I am going to buy a larger one for shower drain line. I highly recommend this product for those with slow draining vanity sinks.

I saw a unit similiar to this when my plumber was clearing a drain line in my home. It worked very well. I purchased this item to reduce the call-in cost of $75.00 and labour costs of $45.00/hour, minimum 4 hours. Price difference is substantial. The unit only works when completely inserted into drain line. Mine burst on the second use, as I did not have the unit completed inserted. It swelled at the hose connection and with the use of hot water and pressure, it broke. I still have a larger unit which works very well and I intend to purchase another "Small" version. Good Tool, Good Price.

A must have in everyones kitchen!

It has saved me a lot of money. Had a couple plumbers look at my clogged tub and both wanted to charge me $250 to $400. One plumber from a "reputable" stated he could not fix the tub issue and he was the plumber who caused it, when fixing another issue. Bottom line, I fixed it myself free with $8 bladder (already had bladder). I am not a plumber. The professional plumbers wanted to charge me upwards of $400. Giving me over explanations of the mechanisms with in a tub drain, how they cannot use a snake and have to do all this "technical" BS. It works great and is a great price. You can use it for common drain clogs.

Not much to say about this little thing other than IT WORKS just fine. Also, think about trying this ten dollar tool instead of calling a four hundred dollar plumber.Don't forget to also buy a rubber stopper type plug to close off a vent pipe or else you might not get enough pressure.

I bought this to backwash a clogged skimmer for my pool. It was a straight shot to open my pool pump cover and insert the device. The piping is PVC and standard size for a pool, I think around 2” internal diameter. I think the size ratio was good since this product was rated for 1-2”I have a graduate degree in science and am pretty handy, but I’m not cocky so I read all the packaging and watched the product video online. I was still nervous as hell about possibly cracking the pvc so I decided to trial the device on a poolside deck drain made w the same exact pvc pool piping.1. First impression was that the rubber quality is very rigid and unflexible prior to use2. We opened our water valve w extreme caution, but soon found that varying pressures did not cause the device to expand on its own. I found that a little curious since I thankfully have really high water pressure and the hole at the tip is really small3. When the drain accumulated some water there was enough back pressure to trigger the rubber to expand.4. Once triggered it got huge quick! It was so fast that it scared the crap out of me and we cut off the water immediately5. It had a tendency to slip back out of the pipe! No matter how we toggled the water and despite me holding it firmly in place, it would start herniating and slipping backwards when inflated.6. We trialed this in a very straightforward drain. it scared the crap out of me because I kept thinking it was going to explode!When I was satisfied that we could safely use it, we went ahead and put it in the pool plumbing. We did not get good results. A very small amount of water came back through the skimmer, but the system actually pressurized to the point that it stopped flow from my spigot! After slight leakage allowed the pressure to come down I was able to remove the ballon and it was shredded. First real use on a clog and it exploded. Weird that it could be broken and still hold pressure so I wonder if it was inappropriately expanded to block its own outlet. Not sure how since it was a straight pipe.Garbage. They probably need to use a different grade of rubber. This one takes too much pressure to expand and then just blows up!

Ok
