I have had a lot of trouble getting some non-return valves out of some stoves. The last one that wouldn't come out I notased the tool was over one side as I was trying to unscrew the valve. Thinking about this.Aftr taking out the hand grip of the tool. With my lath I made up a sleve that fits over the shaft of the tool and inside the pump rod. this holds the tool in the center of the tube. Assembled it all again then tried it on the same valve. With a snap and out came the valve. I am not saying it will work every time but it has to be better.
Now it will stop on my valve tool. It has steps in it ror all the differant size tubes. This is13mm,16mm,17mm,and 18mm.
Has any one else done this type of thing.

Hey Albert,

I use an old, large flat-head screw driver that I dremeled to the right size to fit the slot on my stoves. Then I carved a cork to fit inside the pump tube and slipped this over the screw driver handle. Does a good job of centering the tool.

Might be easier for those of us who don't have lathes (you lucky bugger).

I priced some prickers to be made. The quote was Aust'n $30.00 each for a quonaty of 100. This totaled to $300.00. Who would pay $30.00 for a pricker. So I bought a lath for $1200 and started to make my own prickers. It is only a cheep lath but is straiter than my eye and hand. Albert
