my answers are in blue.
whats your tds after your Ro membrane? 5-30 tds
Are you running an auto balancing system? yes
Are you having to back flush the system often? no it automatically back flushes when needed.
Are you running an auto flushing system? see previous question
Are you pressure feeding the ro system? no, just house hold pressure 55-65psi
how big of a di tank are you running? mine is 1/4 cubic ft.
how often are you having to change your resin? depends as i run straight di sometimes for small jobs. usually 2 -3 weeks with moderate daily usage.
Do you generate on the job or at your home/ shop? both
whats the tds before your ro and after the ro? 224 tds before and 5-30 after.

Oh gotcha, you have a "perry" system...

BTW my booster pump runs off my TM 12v .
80PSI @ 5gpm
My system produces about 3gpm

Our experience with RO is less than Lance's.
We do have enough experience to quantify that it takes less rinsing passes to remove prespray with an RO system.
We specifically use RO water WITHOUT any rinse agent.
Less rinsing passes saves production time and removes more contaminates.
Our TM customers with built-in RO claim more shine restored on the carpeting they clean.

I think that a rinse agent no matter the water type is important when using products with solvents. As I feel they help break the bond the solvent makes. along with high heat.

Surfactant residues are the most difficult to rinse out.
pH Builders over 12, are another difficult residue to remove.

Which is a good meter to check the TDS?

this is the one that came with my RO/DI unit.

My Water at my place after being softened is 8 ph....
My brother about 70 miles away sees 7-7.2 ph....
just down the road from me in neighboring towns on the iron range, they are seeing 10-10.5 ph in their city water....
We try not to hook up to any water source except our own to control as much as we can....
I do have a water filter (not as high end as Lance and others are using of course) and on board water softener too....
But our water quality in my local area is pretty tough....

Its amazing how much water ph, mineral content, etc can change in a few miles.
I was just reading an acticle on how drinking ro water can affect your health because the ro has little to no mineral for your body to adsorb.
i have a ro drinking water unit at home, thinking i should just drink tap water and keep the ro water for when i cook, clean. etc.

I ran the magnet on my last machine and I didn't have a problem with mineral build up except a few times. I think I descaled it maybe twice in 18 k hours.
They add chlorine here to the city water and depending if they are flushing the Lines the ph can climb to 8.5
The ideal setup would be soft water going into ro. The membrane will last much longer.
agreed, you will flow more water threw your ro unit faster when more of the mineral is already removed.

I have ran with and without a water softener... doesn't make a bit of difference...
The carbon prefilter takes care of the chlorine.
Faster? Really?
A water softener only exchanges 2 minerals for 1 calcium and magnesium for sodium. the TDS is the same give or take the last regen on the WS.

Is the carbon filter in the unit or something extra
How much water before you have to change it
Lance Golden

Gene I always run a 3 stage prefltration before RO , Pleated, a carbon block, a sediment filter prior to RO.
The carbon removes the chlorine.

The carbon block I get, suggests up to 35,000 gallons before replacement.

get from where, curious minds want to know
oh and can the ro system be mounted flat or on a wall
the sodium is more soluble and keeps your ro unit from needing back flushed as often. because the minerals that the softner is taking out are harder for he ro unit to process and can start to clog up the ro membrane. since I have an auto balancing / auto flushing system and you don't I don't expect you to understand the higher flow that i achieve when i run softened water as you have a pressurized system, which you get higher flow than me because of the pressure. But my ro membrane will probably last longer in my lower pressure system due to the auto balancing and auto flushing capabilities mine has.
