The standard method to close the leaking seals is rubbing vasoline over the
valves into the leaking gap. In this way the vasoline works as an additional
sealing. Works great but must be repaeted about every time the tanks are
filled with water.

The dump valve on my Nimbus 3 are leaking - one leaks about 10 litres
overnight, another 10 litres an minute, the others somewhere in between.
I'm looking for help on how to go about sealing them better.

I will get some new springs manufactured to push the valves closed but I
would appreciate help on how to renew / refurbish or repair the existing
seals themselves.
