RO/di machine headache

[Craigdillman]

tap TDS is 250

Thanks for the help guys I'm going to tackle the rest of this tomorrow (with a bomb and get a real unit for once lol )



Cheers

Ok, good luck.

If you end up buying a new unit, Vertex makes an RO only unit (for a good price too!) that you could hook up to your DI cartridges. It comes with filters and a membrane.

Ok thanks Yea was looking at the vertex ones or one from Bulk reef supply they do a RO only one as well

Ya but then you pay shipping and exchange which is like 35% right now if you pay with a credit card. Buy Canadian!

Check your plumbing, paying attention to where the flow restricter and the output RO is coming form
Maybe the flow restrictor is toast. Take it offline and blow through it when it is dialed closed

Might be an idea to have a look at the drinking water pressure tank part of your system to make sure that's not causing you all the grief. Perhaps bypass it if you can & see what happens. I don't have anything like that on my system, so don't know anything about how they plumb in, might be a red herring. It does add complexity though & more things to go awry. Personally for drinking water, I simply bypass the DI stage when I do a water production run & deliver the 1st 6 gallons of water to a standard water cooler jug. This has a side benefit of ensuring that when I do open the valve to the DI stage, I know the RO from the membrane is as low as it will get. Short production runs are hard on a RODI system & filling the drinking water pressure tank could be considered a short production run. It will take a few minutes for the RO output TDS to drop to optimum based on your tap TDS.
