Is these tanks regulated for so many gallons of water per minute? If so how many gallons can I expect to use per minute? Thank you

Working correctly with this system, you can expect .5-1 gallon per minute with an incoming psi of no greater than 50. 

On the Resin section of your website a question was asked regarding how much resin to refill the tank. It stated: "How much resin is needed to fill a xero pure di tank? You'll need a 1/4 cubic foot." On this page it states you will need 1/2 cubic foot to fill a 1/2 cubic foot tank, which makes more sense to me. Which is the correct answer? And why the discrepancy?

There are different amounts of resin required for different systems. For te XERO DI Tank, if you purchase the 1/2 Cubic Foot size, you will need 1/2 Cubic Foot of resin to refill that. If you select the larger, 1 Cubic Foot tank, you will need 1 full cubic foot of resin to refill that tank. The 1/4 foot measurement you are referring to is in reference to the XERO Pure DI housing on a multi-stage system. We do agree that the details of that are unclear, so we have gone an updated the wording on that question. 

How long will it last in Raleigh, North Carolina?

Hi Bruce! Great question! How long your resin lasts will be determined directly by your TDS and frequency of use. Your area in Raleigh averages around 110 TDS, so this would be a feasible choice for you! You can use this CALCULATOR to have a more accurate calculation for your resin costs with your specific zip code, and frequency of use. How long it lasts specifically varies, where we recommend replacing it when your TDS begins to consistently creep over 10 PPM, or every two months -- whichever comes first! You should be able to expect over 800 working gallons of pure water with each resin refill. 

Is there a video on how to replace/refill the inside resin beads? Also for the 1/2 cubic foot tank do you make cartridges for simple and easy replacement?

The DI Tank does not have a video just yet, but simply needs to be emptied out, rinsed, and refilled with fresh resin. The 1/2 cubic foot tank takes 1/2 cubic foot of resin to fill it properly.

How do you replace the resin? Can you buy resin?

Great question! Changing the resin is super easy! Simply empty the tank, and refill snugly with fresh resin! You can purchase replacement resin HERE.

I’m in an area with a TDS of 200. How long will my resin last if I’m using it around 5 hours per week?

We would recommend going for the XERO Pure instead. The XEOR DI Tank is only recommended for TDS of 100 or lower for it to be a cost effective option. You will burn through resin changes very quickly.

What is the max TDS that this will work. We are in Idaho Falls and looking for a D1 system. Our TDS is 350. We only do residential work and are interested in this product or the Unger Single Stage.

The XERO DI Tank is meant for lower TDS areas. We would not recommend any single stage system for any TDS higher than 150 at the very most. The reason being that is it not cost effective in the long run and you will burn through resin very quickly. We would, however, recommend the XERO Pure, or PWP Single RO/DI. If you have questions or concerns, please respond to this message, or give us a call at 862-266-0677 to discuss directly with one of our product specialists.

What is the max flow rate recommended for this at TDS of 300ppm to still lower TDS effectively/reliably to below 5-10ppm? I wondering if I can run this continuously with a water fed brush or if I needs to pre-run and fill a tank from which I would then pump DI water for washing a 40 panel solar array.

We would not recommend this tank for a TDS of 300. This is designed for a TDS of about 100, anything higher, we would recommend a multi-stage system like the XERO Pure, or XERO Pure MAX, both of which will run continuously.

What is the best way to store your DI tank between uses so the resin remains active? I plan on using the DI tank roughly 4 times a year.

Hi! To keep your DI tank safe in between uses, alwasy keep water in to keep your resin hydrated!

Would this work well for washing cars?

Hi! Great question! While pure water is a great choice to clean a multitude of surfaces, and is safe to clean cars, you have to be careful with how you apply pure water as most waterfed brushes will scratch the finish.

I’ve been cleaning windows for years, does a zero ppm water system remove the need for a squeegee when cleaning windows?

A XERO system can remove the need of utilizing soaps and squeegees. You can find out more HERE, or give us a call at 862-266-0677.

Can this system be stored on its side if it is not in use? Like if I'm traveling from one job to the next.

Yes, some people even mount the system to their vehicles.

How long does the resin last

The life expectancy of resin depends on how hard your water is. The harder your water, the more frequently you will have to replace resin. Give us a call at 862-266-0677 for more detailed information from a water fed specialist.

Will these ever be In stock again?

Hi Jarel, we are hoping to have them in stock in a number of months. We will announce when they are in stock, so keep an eye on our social media pages for updates.

Does this tank come with the resin

Yes!

What is the flow rate at the brush of the Xero DI 1/2 c.f. tank with 75 psi input pressure?

A DI tank should never and does not need anything more than 30-50 psi coming into it. The maximum flow at the brush should be .5 to 1 gallon per minute. Any more is a complete waste of water and money. water going into a DI tank greater than 50psi will not be properly cleaned.

Does the tank need to remain upright during use, or can I lay it down on its side?

Always keep the tank upright. Do not lay it down.

What are the dimensions of your tanks ?

The 1/2 cube = 8' x 24" The full cube = 8" x 40"

How much virgin resin do I need to recharge a1/2 cubic ft tank?

You'll need a 1/2 cu ft.

How much does the 1/2 Cubic Foot tank weigh?

1/2 CuFt tank weighs aprox 5.2 pounds

Do these DI systems come with a tds meter reader?

When you buy the Di package, with a pole, yes they do. Without the pole, no they do not.

What is the Total water capacity of the 1CF tank?

The water capacity of the full cubic ft di tank is about 7.5 gal. The 1/2 cuft water capacity is about 4 gal.

Is this good?

Yes, this is a great system for low TDS/low frequency of use, or as a starter system.
