Got this from a deal a few weeks back. The bottom rubber is too hard and doesnt grip onto the drain to create the desired vaccum effect. Also when you pull the handle up the gunk comes out the top and splatters you.

You must've had a poorly fitted joint anyway.
There is no way this can cause anything to become detached.
The weight of the blockage might've dislodged a seal somewhere.
Either way, it was a fail waiting to happen.

Same thing happened to me once so now I never use one of these on any waste system with hidden push-fit fittings that I can't see because there's always a risk that the water pressure from this will push a joint apart rather than clear the blockage.

I'm using one for years now. Most effective thing for sinks.

    Could do with this tbh, very good deal. I assume it would work with toilets?

    These are brilliant, used one in anger recently. Worth twice the price.

    @weezyy won't work on toilets. Sink/Bath/Shower traps where you can make a seal with the surface

    We have one… not really the right thing for toilets but depending on the shape of your inner bowl it might work… ours is rigid rubber and doesn’t make a tight seal in the toilets .. plus pulling up dirty toilet water would be gross for cleaning it later. Brilliant at sink blockages with a flat surface though

    I have one but as per other comments, you need to make sure the sink has a big and flat enough surface for the rubber seal! My sink is tiny so it doesn’t really work fantastically!

    Wickes have one with a bigger head on that could possibly be used for toilets goes up to 152mm for £7.85. I've not tried it on toilets myself, I use it for flat flow showers as they have a bigger waste grate.

    I’ve had one for a few years, but it came with two different size heads- they screw on. Not the case anymore? For toilets, I use one of those plastic concertina things, which are brilliant.

    Can't understand why people's toilets are blocking up.
    Mine has never blocked.
    What are people trying to flush down there, nappies
    I did read one woman was trying to flush nappies down her toilet

    Use a mop to create pressure as you push mop into bottom of toilet. It works.

    Injects water? Only if standing water there. Surely it releases air?The beast I have from Lidl is a better version of this - not seen for sometime though.

    Every home should have one. Will save on a lot of plumber call outs and purchasing costly drain unblocking fluid.
    Don't forget to cover the overflow holes with a cloth to create more pressure when plunging. Seen a plumber do it

    Tried it once years ago. Complete waste of time! I'll stick to a regular plunger.

    works on sinks, baths and toilets. for a better fit on a toilet/sink if wrong size; standing in a bucket of hot water lets the rubber soften. then push right down the loo till it seals enough. quick pump and done.

    I normally use this weekly in the family shower, just to ensure hair (no longer mine) doesnt block the u bend in any way! its approx 3 yrs old and still going strong.

    n.b. also it stops standing in water in the shower tray!

    Bargain !

    You need three hands. One to hold the unblocker in position. One to operate the plunger and another to hold a wet sponge or rag over the overflow.

    I got one and can’t figure out how it works

    We used one of these in our shower after OH dropped the shower head spilling stone beads down the plug hole and completely bunging it up. Two plunges with this and it was sorted. We'd been quoted £200 to fix it, so needless to say we're rather happy with it.

    Remember that if you have a double sink in the kitchen, someone needs to hold the plug down in one of them as you clear the other. Finding out the hard way that you forgot is not pleasant.
    Also block off the vent hole at the back of the sink to increase the pressure.

    Even better fill a bucket of water. Not so much water it will go over the bowl and the pour it straight in from waist height. The extra force from the greater volume of water and the height you are pouring it from will clear almost any blockage.

    I'd also be wary of using one of these, having managed to blow a waste pipe apart at a joint using a regular plunger too aggressively on the down stroke while clearing a blocked sink. I now press down gently and use the plunger to suck the blockage out (with the overflow blocked of course).
