Cheers Guys, will look them up.
Both my machines are steempro's a powerplus & an older powermax, the newer machine gets very well used & the older one as a backup or if we're really busy, they both take a fair but of abuse from the boys that work for me.
I usually end up robbing bits from the older machine if the main one breaks down but had a drama the other day when I was using one & the guys the other....numb nuts had left it in his van the night before, frost had got into it, the head exploded off the pump when the seals went! Anyway ended up having to strip pretty much every water connection inside & re seal it, using up my spare pump, stash of hose & spare brass connectors (frost had split 2of them) so I thought I'd better restock, need some chems as well, my local place has closed so where better to ask for advice than here!!
Cheers
