I change a lot of taps, very popular job in handyman land. Getting to the tap connectors & backnuts is a constant problem and with 'designer' & mini corner sinks it seems to be getting harder.
I've got several so called basin wrenches which claim to fit tap connectors & back nuts, but don't - they can't because tap connectors & backnuts are different sizes.
The self adjusting basin wrenches do work, but especially under a corner sink there is rarely enough room to get much of a turn.
I've looked at the Armeg Jaw Dropper wrench set for a while, but the price - £40 ish - made my jaw drop! Maybe thats where they got the name?
Had a job on new years eve to change basin & bath taps in a poorly maintained & very old house. Thinking it could be a bit of an embuggerance job I decided to bite the bullet & buy a Jaw Dropper set. Present to self & I could always take it back if it wasn't any good.
I'm keeping it! After one use you would now have to prise it from my dead cold fingers.
The ads aren't that clear on how it really works, the 'more pictures' feature on the Axminster site show the details fairly well.
To undo a tap connector you have the round jaw locked up against the hexagonal jaw & it acts as a guide by sliding up the pipe until the hex jaw locates on the tap connector. You can actually do this without being able to see the joint.
To undo the back nut the round jaw is slid out of the way leaving a very small profile hex jaw which would fit in the smallest corner basin space.
Side handle means you can get a lot of welly on reluctant connectors or back nuts.
So - it does exactly what it says on the tin. Only cons are the price. It comes in a moulded case with a stubby screwdriver to adjust the rounded jaw. The case just takes up space & I already have screwdrivers, not including those would knock maybe a £5 off the price?
If you change a lot of taps its well worth the money, its certainly going to make my life a lot easier. Possibly a bit expensive for occasional DIY use unless you have a large project on.
