420 litre water tank

the 34 holds enough to cleanout on two jobs besides refilling the waterbox. i think its like 150 gallons (I run a 2003 34m schwing)

do they all have plastic water tanks ?

Not sure bud, my tank is plastic anyways

32 and 39 meter schwings both have plastic tanks. I have never ran out of water for clean out. Two jobs back to back are no problem if you get your prime water from the Rm trucks.

The 34m - 39m I ran both had steel tanks,which would crack (hence the plastic tanks).I ran a garden hose from the top vent to rear of pump for filling tank with rm wter,worked great.

You are better off with the plastic tank, will not rust....
