Just so you all know,I informed the owner before I used the kettle that there was a chance that there might be a bit of shrinkage but he did not mind because the carpet was a right mess.
Also I tacked the carpet down before I started to reduce the chance of shrinkage and used a turbo dryer on it straight away.
I took a small calculated risk with the owners permission and it payed off.
Nothing ventured nothing gained
Thanks for all the feed back.
