Hi Guys, I've just replaced the main tank washer because of a leak, the old one was flat and brittle. It's still leaking though! Any ideas? Its a Vapalux M1....
By tank wsher, do you mean the washer between the tank and control cock? Have you checked that the mating faces are not damaged. Do not over-tighten as that can displace the washer. Is the washer a Fettlebox item?
It could be the gland washer. Try tightening the gland nut but not so tight that you can't turn the needle control knob, if that doesn't work the, the seal will need replacing. Take off the green knob and the gland nut, remove the old seal from inside the gland nut and fit a new one. If you find it difficult to remove the old seal, burn it out with blow torch - you won't harm the brass. Still leaking ? Do a dunk test. Empty the tank, remove hood + burner and glass. Place finger (or thumb) firmly on top of vapouriser and pump plenty of air into the tank. Hold tank under water, air bubbles will indicate location of leak.
Thanks very much for Your replies Henry and R100, but I was just about to do an edit to the original Post as I've fixed it. I neglected to replace the rubber washer on the Vaporiser also. That's done and no leaks. The washers come from a kit I got from Julians site, a tin full of Bialaddin and Vapalux parts. Again thanks for Your replies, I guess we learn as we go along!
Yes, I have 2 M1's Both in lovely condition. The other one has Brass coloured fittings and same green colour.
