@ the moment im using 300 ro, and 10 inch di vessel, at the moment im only using around 5 x 25lt drums just to do tops . i still use ladders on easy acess tops in compact areas. my dielema is do i start using a 11 litre di vessel as and when needed, will make life easier as im doing water as and when needed in litchen @ night when no one in and out of kitchen. my tap water is 106 on tds meter. it takes roughly 1 hour to fill 1 x 25litre drum from ro. which means setting up @ 9pm untill 11pm. i dont have acess to fit outside as kitchen is facing front of house , this is why i have to use kitchen set up. i know lads use large DI vessel from tap straight to drum, have any of you guys worked out how many 25litre drums you can get filled from 1 batch of resin in 11 ltre di vessel. out flyer dropping again today, got a lead from a new customer, got to be first., its getting a cut throat bussiness out there.
