Re: IML: REPLACE VALVE SEALS

["Rob van der Es" <r.vdes@xxxxxxxxxxxxxxx>]

Both techniques should work !

But I think that the rope technique is a little safer to carry out.
Imagine what happens if your air compressor hose suddenly get
loose...
I believe quite a bunch of people on this list have used both tricks with 
good results, so it is just your personal preference which one to use.

As mentioned above, with the rope technique you don't have to worry about a 
sudden airpressure drop down!
