No mate, bought the cheap ones then bought 2 kits to modify them from the 7.2 to the 5.7 but all this is expensive to me as I've only just started out on my own, up until now I've allways worked for the same company, but after buying a van, machine, chemicals ect and I still need to buy a scrubber, the £150 odd is a fortune at the moment. But I'm hoping it is the vacs and not the element.

ah , i see .. yes 150 is still a lot ...   thought u may have spent 500 on 7.2's or something !

Haha no mate was going to, but decided to give the 5.7 modification a go, do you think it could be the heater element though, even though the heater isn't plugged in when the vacs blow??

No i really doubt the second cord would have any connection with the first ..
The vacs should do it ...   u may see an increase in power also as that 7.2 vac you listed was a 1300w model with not great lift or cfm .
cant think what else ... some machines may have a relay from the switches which could fail ... but im sure thay would have mentioned it .. or you'd see it inside somewhere .

Didn't think the heater would be the problem in this case, definatly no relays in there, so like you say it's got to be the vacs, one thing I did notice is that everything is earthed via nuts and bolts but all the earths end up on one wire leading to one bolt if that makes sense, does each bolt that has say 2 earths connected act as a new earth or should every vac, pump ect be earthed to a different earth point, hope that makes sense, but quite hard to explain

hmm .. kinda hard to picture those earths alright  but it should just all connect together as one  .. id say they earth the main components ... and just run earths to various locations .. the metal base etc for safety

Ok so box of goodies came this morning  , both vacs seem to work ok but only wired them up and tested, as waiting for a company to send me through a fitting kit to make them fit, only question is the new motors don't have a earth they only have red and black wire, the old motors had a earth?? But the new motors sound like jet engines compared to the old ones.

[Kinver_Clean]

You earth the motors by running a wire from a mounting bolt to the main earth stud, assuming they have metal snails not plastic.

Cheers for that mate, just me being thick. Right the vacs are working ok, but on the pressure thing for the vac suction it only reads 0.2 hg is this right, it reads this when I'm sucking the water up not when the wand isn't in contact with the carpet,

[john martin]

 Its gonna drop during the cleaning process ...  does it read 9.5 when u put your hand over the machine hose outlet ?

[Dan 123]

Hi mate there's 2 sets of numbers, one set is 0,0.2, 0.4 ect the other set of numbers reads 0 , 10, 20 30 , when I cover the suction nozzle with my hand it reads 0.2 or on the other numbers it reads about 6, if that's makes sense,

[john martin]

The 0.2 is kg/cm2 

The 6 is HG  ....   I would expect it to be a little more ...but the gauge may not even be fully accurate at this stage .

[Dan 123]

Brilliant mate, thanks a lot for all your help, I really appreciate it, I'm going to strip down all the joining pipes and make sure there's no leaks ect before I put the machine back together for the final time (hopefully)

[Glynn]

Dan,
where did you get the new brackets etc ?.

[Dan 123]

I spoke to a company on eBay about a vac and if it would fit my machine, they said exactly the same as everybody said on here and told me to convert to the 5.2 vacs, they said they sold the fitting kits for 12 quid each, turned out to be a few long bolts and a cardboard cutout of where the bolts should go, so in the end I just used my old brackets, bent them abit and they fit perfectly, then a trip to b&q for some pipe connectors ect and that's about it really,

[Ian Gourlay]

Use a Carpet Brush to start with  cost about £25 .
Then buy something like a  new Sebbo Duo or a rotary then you can offer alternative methods. Apparently you need a rotary if you want to join the alternative carpet cleaning organization
 
Again be aware of Second Hand Scrubbers you never know what you might get
