The ONLY downside to DI ONLY filtration is that you do not know when it is going to expire, so having two tanks in series makes great sense - the first is the 'WorkHorse' and the second tank is the redundancy.
We include a CHECK-iT TDS METER with the KIT ( you may need to supply your own CR2450 battery due to a civil aviation crackdown on devices with batteries). Connect CHECK-iT under your brush, and you can know with certainty at any time that you have SPOT-FREE water.
You will also get GARDENA Quick Connects back to garden hose, and RHINO TUBE.
DI Resin is not supplied - it is available locally worldwide - simply Google 'DI RESIN MB400 MB115'
Please Note: Comes with Orange GARDENA Fittings. Should you need the Green Hose Connectors, they can purchased separately.
Use virgin resin for the longest life, alternative to ATOMIC RESIN is MB400 from Purolite and MB115 from THERMAX. If you find a nuclear grade resin, it will last 20% longer and usually costs 20% more.
If you experience high TDS from well water, remember, you can clean the windows and frames the first time with tap water, and then do a second pass, glass only, 15 seconds per window with DI WATER to polish the job.
Please Note : An RO is simply a PRE-FILTER to DI with one goal - to save DI COSTS. An RO does not purify water any better than DI, and you cannot spend $5000 to get a better quality of water than from a DI TANK. Getting an RO is NOT a decision based on the TDS of your local water, but rather a decision on how much it could SAVE you in DI RESIN costs compared to operating DI ONLY.
