Hi m.b.s,
How long and aprox' how much water have you produced since the canister was new?
I have a 100gpd RO and a 750ml DI polisher. The water from the RO is about 004 to 006 and I produce about 1700 to 2000ltr of pure water in 2 weeks when the pure goes up to 001. I change the resin every 2 weeks.
I run my system from Wed to Sat which produces me a weeks supply. After the first week I shake the DI canister before starting up the system again.
