thanks guys
ive been away for a long weekend, fri to monday in butlins ( if any1 wants to hear about it, let me know

) thus the lack of replies from me
cheers Jeff, ive used Sikaflex and recommended it to others, tbh i didnt think of it in this instance, good call though
cheers elite mike, i didnt think of them, would suit what i need, its allmost he same footspace as a 25 L barrel and i can cut the top off and glue it at the height i need
cheers Pristine Clean, that was the way i was going to go, mould the fibreglass to form a container, as you said, alot of work, but if done right it should last me a few years, then again, the space saver butt idea will do the job
dai, i have ditched my old trolley and im not using a sack truck, the diea is that the sack truck is lighter to lift into the van, i'm just trying to do as little lifting as possible with my hernia op ( its now been allmost 7 weeks and today was my first real day back in work and i really did struggle after a few hours )
i am now sub-pumping from my van tank in the van into my sack truck, i thought on a bigger tank on the sack truck ( something like 35 - 40 L ) the weight of TWO 25 L barrells is too much, as i'm doing up and downstairs with pole now, i wouldnt mind 2 houses out of 1 trip to the van ( thus need to be 35 - 40 L of water )
