RO system

It does have DI, but it's a horizontal canister. Far less efficient than a vertical canister.

 

ok i did a little reading and i have a light bit more understanding as to what ro/di dose. this is the one i will be getting ( thank clonefarmer)

75 GPD RO/DI 5 Stage Standard System - English

is there anything else i will need for this?


p.s in the near future i plan on get a bigger tank and then have this auto fill the tank when need be so i want to make sure i have all i need. so i dont have to spend twice.

 

Expect to buy a TDS meter with that unit, since it doesn't have one standard, and a TDS meter is required to know when to do maintenance (as stated above, in case you weren't reading). You can't figure out when your DI is exhausted, or when your RO membrane is shot, without one. Once you add the $30 for the TDS meter to your linked unit, already $160, the CSP-DI is within 10 bucks, and still has better prefilters, a better RO membrane, and a better DI stage.

I seriously recommend going with the CSP-DI at the Spectrapure page linked above. It actually gives you everything you need, unlike both the ones you linked.

 

^agreed.

 

A TDS meter. Some of the BRS units have one, some don't.

Auto shut off kit. You can plumb the RO/DI unit into an ATO or other holding tank. When the container fills up the float shuts off the RO/DI unit.

 

Anyone using the shut off kit. It looks like it just shuts down the reservoir. Is the water just running out the waste line or does it stop the ro unit itself.

 

There is an inline shut off valve that comes with the kit as well as a float valve. When the float valve shuts off the RO/DI water, pressure builds. The build up of pressure closes the shut off valve and stops the waste water.

Here is a link to a youtube video that explains how the shut off is connected.

 

Thanks for the link. Years ago i bought some kind of shut of valve that cost much more and i never figured out how to install.

 

You are still better off with the CSPDI from Spectrapure at $199.
With it you get a dual inline TDS meter, inline pressure gauge, specially treated and tested 90 GPD high rejection rate RO membrane, 0.5 micron absolute rated prefilter, 0.5 micron 20,000 gallon chlorine guzzler carbon block and most importantly custom blended SilicaBuster DI resin that will outlast and outperform any other resin by at least 30%. One of two resin changes and you have your price difference and it saves you from then on.
The difference in the membrane alone is worth the difference, their membranes average better than 98% rejection compared to dry untested off the shelf Dow membranes at 96-97%. What you need to know is for every 2% you increase the membranes efficiency you DOUBLE the life of your DI resin. Talk about a huge cost savings and thats for as long as the membrane lasts which can be 5+ years.

An auto shutoff valve shuts off both the treated and waste flows when installed properly like pictured here:
