I'm weighing up rebuilding my DIY DI filter comapred to simply buying a commercial system.
If I buy a commercial system I will want a RO / DI unit. I'll want to run off a feed before the DI part of the filter for drinking water - so RO drinking water and RO/DI reef water.
Filters available in New Zealand are really not up to par, and they're also woefully overpriced. I plan to import one from the US, fully expecting that freight will double its cost - I'll still be saving money over buying an equivalent filter locally.
In terms of RO/DI systems what is the best value unit? I've been looking at the "Dave's ReefPure" units and they seem reasonable.
Are there units that come standard with two taps - one for RO water and one for RO/DI? If not, how easily can I get the parts needed to make a modification to acheive this? I wonder whether a "T" off the feed line would be enough, or whether I would need a non-return valve on the DI resin side of the connection.
