How am i gonna get this undone ???

This is stuck - I want to get it open just to check i have no water in my inner hull - I tried to use a 50p and a pair of pliers and the 50p bent.

I bought a tool from the chandlers
(see pic below) and i still cant get enough purchase on it - the tool just jumps out the slot.

I thought of using an impact driver but 1. i don't have one and 2. i don't think a standard screwdriver blade is wide enough and will just chew up the slot.

Any Ideas...

try some wd40 or diesel on it. then get a wood augur bit from hardware, grind down to exact size and put bit into a brace. this should allow you to put your full body weight against it and twist. it should come off. try not to use a hammer as it might dislodge the complete fitting and create a leak.

Best of luck

If it's stuck fast I would undo the self tappers/woodscrews and remove the whole fitting so that I could work on it in more comfortable conditions.

Once you have a decent tool warming it up might help , ie hot water or just a rag soaken in hot water , or a hair dryer

Hair Dryer?!! Why not turn the central heating up and stand at the back door waving a tea towel!! Try tapping it with a hammer Roy, then a big screw driver gripped with a pair of molegrips.

These are commonly used on narrowboats for water, diesel and black water tanks and regularly sieze up. We use the method Codprawn sugested, an old wood chisel ground to fit and a pair of mole grips, has never failed for us. Before refitting it smear both surfaces with vasaline so that it will be easier to remove next time.
