So no real advice yet hello stuart mate .
Once you have checked your tds you may need an RO and Di i got mine from
www.purefreedom.co.uk they are well priced as well .
Next what size tank will you need i have a 400ltr flat tank which lasts me a good day if your van allows get a 500 ltr tank to make sure you will get a really good days work . The size of tank will depend on your van payload and the size of your load area in the back of your van .
You could get your tank from Pure Freedom as well .
I have my ro and di in a shed at home and make pure water while out at work so when i get home i can fill my tank in my pickup truck for the next days work , I store my pure water at home in water butt as it is not under cover .
As for pole brush and hose reel go to
www.gardinerpolesystems.co.uk most lads use the Slx but a CLX will be very good first pole based on other peoples reviews on here , the clx 22 will allow you to clean up to the top floor of a 3 storey townhouse ,
As for the brush i would recommend the super lite single trim standard as it will take more abuse than others ,
Hose reel i have the premium metal reel which is £54:00 with connection pack , Then put 100 mtrs of 6mm microbore on your reel .
To connect your pole to hose reel hose use the EZ-Snap fittings .
And last of all nearly forgot pumpbox and battery i use the Streambox from
www.streamlinesystems.info it is the one with the digital flow controller .
And transferring water from storage tank at home into tank in van i use a pond jet pump which pumps up to 75 ltrs a minute go to a local aquatics shop explain what you are going to use it for and they will sort you out with everything you need for about £30-40 ,
Hope this helps Mike
