SpectraPure MaxCap RO/DI

PS. I got a 100% RO membrane rejection rate straight off and I've never seen water so crystal clear and polished in my life.

Cheers,

Do you have a dual TDS meter?

Yes, which gives two readings on each meter by way of a toggle switch. First meter reads tapwater TDS in and TDS post RO membrane stage (stage 3). Second meter reads TDS after first DI cartridge (stage 4) and finally TDS reading of final product. So, 4 TDS readings all tolled.

Cool, two Dual TDSs.

What are the 4 readings.

My post RO is 1-2, and my post DI is 0-1.

At this point raw tapwater reading is 15 ppm; post RO reading is 0 ppm; and obviously if post RO is 0 then the rest....post MaxCap DI cartridge (stage 4), and post SilicaBuster cartridge (aka finished product water)....are also presently at 0 ppm.
The advantage to having the 4 readings is one can determine the status of the RO membranes [(Tapwater ppm - post RO ppm) / tapwater ppm] x 100 = membrane rejection rate %.
And.....one can determine the status of the first DI cartridge (the MaxCap cartridge). When the post MaxCap DI cartridge (stage 4) reading is 75% of the post RO reading, it's time to replace the cartridge. The indicator for replacing the second DI cartridge (the SilicaBuster) is simply a rise to 1 ppm on the last TDS reading. (The product reading).

I received the following email from SpectraPure today. The VP, no less. Turns out they weren't aware the toll free phone service wasn't available in Canada.
Okay. 9.5 then, for customer service .

Hello-

I was just forwarded your email by scott.

First and foremost, I want to apologize for the time and trouble this has caused you. We will of course send you a new MaxCap cartridge and whatever else is needed to return your system to tip top operating condition. While we strive for zero defects, over the course of thousands of systems each year, and introduction of new systems and the attendant learning curve to build them, we do unfortunately experience problems that can and must be corrected by us. This is such a case. The initials on the build sticker tell me that the system was built in December by a former employee, and double checked by a new floor supervisor. Our actions include having this floor supervisor go thru build requalification on this system to verify he understands correct assembly to our documented build specification and drawings.

Regarding our phones, as a result of your experience I have found out that our toll free Canada service was dropped by our phone service provider without notifying us. I will be work to change our service contract to correct this as soon as possible. I too appreciate Scotts prompt response, as that is what we expect from all of our communication channels.

Again, sorry for your poor first experience with this new system, we will correct the problem and believe you will be impressed by a properly operating system for its renowned performance and low cost of ownership. If I can be of further service, do not hesitate to contact me.

Tap water is 15ppm!

That is amazing. Most bottled water that is RO purified says less then 17 ppm.

You almost don't even need RO, and your DI should last for about 43 years!

I thought our tap water was good at less then 100 ppm. Many places have 300, 600 or more ppm.
