Need Help Purchasing an RODI Setup

[nor_cal_nano]

I'm looking to buy one of the refurbed spectrapure units in the near future. I'm sure I could have researched this topic a bit more before posting but I'm in a bit of a rush to purchase the unit before they run out.

 

Anyways, I live in an apartment with a full size washer/dryer. What all do I need to purchase to get this thing up and running? Do I need a TDS meter? Should I hook it up to the sink or washer? What parts would be needed there?

 

Is this a good unit for my application?

 

Also, it would be nice to have on hand for drinking water. My girlfriend is really picky about how water tastes....

 

There's some kind of by-pass for the DI portion correct?

Anybody? Just looking to be pointed in the right direction.

Maybe call SpectraPure and ask? Probably the fastest way to get the answers to your questions.

i just bought a brass "Y" connect at home depot (about $6) and connected mine to the cold water on my washer, seems to have the best pressure there.

I also use a brass wye to feed the washer and the RO/DI off the coldwater line.

You will need the TDS-3 handheld TDS meter to monitor the system condition.

The Spectrapure units come with a hose thread adapter that will screw on the brass wye, a hose bib or a garden hose. If you want to use it for drinking water too, mention that to Spectrapure and have them install a DI bypass valve so you can use RO water for drinking as well as having RO/DI for the tanks. They are very inexpenisve.

I have the BRS ro/di unit. I have the duel in-line tds that reads off the ro and the di separately so I call tell which one is giving the high tds reading. It helps to know which filter to change.

I purchased the EZ base model Tds meter from spectrapure. I also got a 3 way ball valve to bypass the di, so I should be able to accomplish the same thing as an inline right?

 

Thanks for the responses everyone; that's exactly what I was looking for.

 

Also, azdesertrat, would you happen to know off hand what california's requirement is as far as apartment water pressure goes? My complex says that last year they tested and just barely met the legal threshold or something like that.

If you're using it for drinking water, be sure to pick up one of those pressurized water tanks, and a spigot.

It will save you a lot of headache/waiting/spills/repair bills.

Most state health departments and fire departments set a 30 psi minimum water pressure which isn't very high and not enough to operate a RO/DI system. The UPC and IPC say 40 psi for the minimum and 80 psi maximum for new structures.

[nor_cal_nano]

I think you're dead on with the 40-80 range. I ended up ordering the unit and installing it today. Anyways my pressure is reading right about 41-42.

 

Thanks again for all of your help, both to me and the community.

Try monitoring the pressure at different times of the day. Often its higher at night or during off peak periods when demands are down. You can make better water faster with higher pressure and your DI will last longer.
