Title: drain jetter machine
Post by: joe.b on October 22, 2009, 05:44:30 pm

hi i was just wondering, you can get those purpose built drain jetters, can you use them for driveways etc? or is there some reason why you cant

the proper drainjetting machines run at about 45ltrs a minute or more and this is too much for drive cleaning where you only need between 15 and 22 litres a minute, having said that i have cleared a few drains using my pressure washer and a drain cleaning jet but it wouldnt be powerful enough if there was a serious blockage.

hi trev cant you just turn the revs down on the machine?

Yes but then you have to match the oriface to the flow at the given revs. Flow is inversely proportional to pressure. I have drive cleaning kit and a drain jetting machine. The drain jetter uses 400ltrs in 8 minutes so its not very practical for cleaning drives but I have used the drive kit for drains also

i was going to buy tech cleans drain jetter for pressure washing as it had a hose reel on the top of it which was handy. it produces more pressure than the 15 litres a minute 3600 psi. ???

No more pressure just an increased flow. Its 21ltrs @ 200 bar instead of 220 bar

would that be no good then? i suppose i would be using a hell of a lot of water!!

if the pressure does not increase with flow rate whats the point in having a higher flow rate?

They are totally different machines for doing totally different jobs!
That is why they are called different things. ??? :o ???

Geeez DS, for a man who has been in this game for such a long time and has so much experience, you don't half ask some strange questions.

DS for the given engine ie 13 hp you can have more pressure @ a lower flow OR more flow @ a lower pressure. I myself see no advantage in having any more than the 15 l/min as thats about the usual flow in a domestic garden tap. I started out with the tech clean drain hose and I still use it when I get drain jobs in multi storey car parks where I can't get my hi top in - I put it in the bouncy castle van and off I go.
