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.
Please Note: Comes with Orange GARDENA Fittings. Should you need the Green Hose Connectors, they can purchased separately.
NOT INCLUDED: MIXED BED DI RESIN
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.
