just checked my water tds was 50+ never cheched it last week because i was checking it every day and it said 0 should it rise as quick i had  been cleaning windows all day before checking will the windows be a mess when dry
where is the cheapest place to buy a sack of resin, can you change it yourself

di vessels rise quite quickly must check reg used to do mine 1st job ,midmorning and last thing at night, now dont use di much except for polishing ro water.

Read on here and been informed somewhere else that if you reverse flush the resin for a while it improves the purity of the water but from 50 ? Idont know,but ive done this before when I first started.
 to get by till my resin arrived next day {there is a cut off point for next day delivery]
with most companies its between 12 and 4 most nearer 4ish.
Anyway if ur using a van mount tank put the pipe back into the tank from the di vessell and keep circulating it  thats if your batterys up to it.IVE a split charger on mine so it didnt bother me if it run low on charge. at leastt if u do this u will have a tank full to get you going tomorrow,
