Verified Purchase(What is this?)
This review is from: Silverline MS138 Blast Wastepipe Unblocker 370mm (DIY & Tools)
I bought this based on positive reviews. It seems hard to get a decent seal and was a lot less useful than the old wood and rubber plunger.

This tool will not work if you are not using it properly, you need to seal the tap overflow and position the tool for a GOOD SEAL.
This simple tool succeeded in unclogging both my kitchen sink and my bathtub one. Unfortunately it does requires some arm strength. It took me a while to understand how to properly utilise the tool: the instructions, printer on the object itself, are rather terse and I think that by simply sticking to them you won't use the un-blocker to is full potential. The following worked best for me:
-you MUST seal the tap overflow-prevention device(s) with a piece of tape or cloth: you don't want the pressurised air provided by the silverline un-blocker to flow out through it.
-open the tap until you have approx 2 inch of water in the sink, you can leave it running if required (if the sink is clogged the water should not flow immediately, which is ok)
-position the tool's suction pad in the water and slowly pull the handle to fill its chamber (just like when filling a syringe)
-create an air-tight seal between the sink's drain hole and the suction pad and press the handle up and down slowly ensuring that you have a GOOD SEAL and the water is not squirting out
-repeat the above process several times for at least 30 seconds, then you rest and repeat after 2 minute.
-it WILL work, just takes time (make sure you have a GOOD SEAL)
