Just wondering what the maximum length of 1.5 " whip hose is ideal for using on t/m?
I currently use 7.5 m but could do with a bit more, esp when up and down flats and three storey houses.
Will there be a drastic loss in air flow if i add another 7.5m of 1.5"or should i stick to the 2"?
Regards

None.
Unless its on a stairtool etc !

I use 15ft of 1.5 inch don't have a massive drop in suction, but I use a prowler and that does'nt have a huge vac tank so not sure if it's the same as standard TM's. Find it make the job easier in homes.
-
I will have to agree with Glyn 1.5 is no longer the standard, although I still use it :P but soon to go over to 2" with the first 50ft from machine being 2.5" with two down to one from the waste tank the americans cant get enough of it, just got to source the parts cant remember the max cfm down each size of pipe but im sure somebody does

if your going 2.5 inch they hose inside the machine would have to be at least that as well ? otherwise would you see any more cfm?
-
I still think it's necessary to have the 1.5 for stairs and upholstery and around tight furniture in peoples homes, the 2" isn't flexible enough and will restrict your movement.
And 2.5 will make a big difference on the hose reel, i already have 200 ft on mine so would'nt manage the bigger stuff.

I use a 10 ft whip hose.
I find that works well for me.

i run 25ft whip, i know most TMers will advise less, but with my 4 blower the wand still sticks to the floor more than any twin vac portable.
-
Same here 25ft
-
Think i will just stick to the 25ft, ;)
cheers all

you can get flexible 2" hose, one source is woodbridge, theirs is grey, it's like anything else, it might take a little while to get used to it but when you do, you wonder why you didn't use it earlier. i think the difference in vacuum is substantial. the standard blue stuff is far too stiff and hard work to use, only good for after the flexible hose.

Just to put the cat amongs the pigeons.
If your blower port has a internal diameter of less than 2.5 inchs is there really any actual gain in using 2.5inch hoses?

p.s CHRIS R wheer the link to the lap dancing club gone? :'(
there were some lovely ladies on there.

That not? gunny’s old blower looks a bit rusting inside. ???

Paul What blower is that ?
But in answer dry carpets are not mesured in CFM but air watts

Funny you should bring that up a few years ago on a caravan holiday talking a Belgium chap, who had the same motor as me talked about Watts, I was more into cubic capacity and bhp. ???

Air Watts are Lift x CFM divided by 8.5, if you increase airflow (CFM) the lift will decrease (hg) and vice versa, so you need a happy medium = Air Watts, so when you take Velocity into account you will end up with Velocity (FPM) = Air Flow (CFM) divided by tube area (sq. ft.). so increase the size of your vac hose and you will gain in Air Watts or something like that simple realy ;)

cats per square ironing board me thinks :D
it a roots 36 t-series blower 1 year old 500 hours what'd you give me? out of interest of course
-
Hi Paul are you offering it up for sale if so £5.00, plus p&p of course ;D ;D ;D
Sorry wasnt looking to buy just wondered as I have the tuthill 47 and although not sure what the internal diameter is the external pipe is just over 2.5" from blower to waste tank
-
For carpets 2inch all the way. For stairs Ive a 2ft whip as with suites.
For those really tight areas or three levels of HSL then i'll use the 25ft hose from my portable.
It does make a difference more so in drying.

Sorry I should add also more importantly about friction loss, as velocity increases friction loss increases so with 1.5" hose the velocity is nearly twice that than a 2" hose, so as friction loss goes up with velocity there is only half the vacume with a 1.5" compared to a 2" hose so 2.5" is also better to reduce friction loss.
