Howdy
I've got a spare steampro from years ago in my spare room (or should i say carpet cleaning supply bunker!). That I want to put to good use as back up or for someone else to use on a big job or to sell it in the future. Not decided yet.
Anyways, its got a slight leak on the inside of the machine. Where the vacum stack enters the machine on the inside i.e. above the vacum motors or there abouts.
Its not a massive leak, but basicly if the machine has been running for an hour or so and you where to run your fingers along the rim of the stack (once you've opened up the machine obviously) then there's some moister there. So i'm presuming water can/is leaking in to the vac motors. As I say, its only a little but still cant be healthy for the vacs.
There's must be a little gap or something between the stack and the body that is allowing water from the waste tank leak into the inside of the machine.
Sorry long post as usual, just wanted to build a picture

So my idea is to apply one of these products
http://search.diy.com/search#?p=Q&srid=S8-UKLD02&lbc=diy&ts=ajax&w=sealant&uid=289351764&method=and&isort=score&view=grid&srt=0 to the joint where the stack meets the body. Either inside of teh waste tank or inside where the vacs are. Or both << probably both.
Do you think i'd have more luck with the unibond sealant type of product (the outdoors type, not the type you use in the bathroom. Tried that on a waste tank lid once and lasted half a day!) or the thick water proof coating paint that you apply to roofs?
What do you guys think?
cheers
