City of Calgary 2012 Water Quality Report

Keep in mind though that this report is all the best data from the City, not necessarily accurate for each household. I know my Ca is much higher than the City report.

Looks like your TDS could be anywhere from 156 to 299 according to the water quality report. 299 is on the high side. The only way to test the TDS of your tap is to use a TDS meter. TDS can vary according to time of year & whether the city is flushing lines in your area or not. If you wish to test the TDS coming out of your tap, you should be able to score a small handheld TDS meter at one of the larger home centers or even Wal Mart. I found one at Wal Mart in Vernon in the RV/camping aisles & I think it cost less than $20. Can Tire may have them too. Small price to pay to confirm your TDS. Pressure guages can also be had for about $20 at Princess Auto or other hardware outlets, although by the sounds of it, your water pressure is pretty good. As mentioned, a decent RODI unit will have at least one pressure guage to help monitor when you may need to change one of the filters. I installed a second pressure guage so I can compare the source water pressure with the pressure before the RO membrane. This pressure differential will creep up over time & give you a great indication that a sediment filter is in need of changing.

If you don't want to worry (or care) about the water pressure or the quality of your tap water before an RODI unit the Vertex Puratek 100 GPD is the best bang for the buck. It has a pressure gauge, booster pump and TDS meter built in. It also has other nice features like automatic flushing.
I live in an split level house and don't have access to the water line or space to plumb the unit in so I just pull my unit out of the closet and make water once a week attaching it to the kitchen sink. Very simple.
I found my unit used for about $150.

Thanks for the heads up! I am the same...I dont want to deal with tapping into my pipes and such so I was thinking the same.
Hubs is about to go away again so this will continue to be a work in progress until we figure something out. Have been keeping an eye on kijiji to see if someone is needing to rehome theirs lol

in no rush...so i dont mind waiting.

Pretty much any brand RODI system can be hooked up to your tap without having to cut into pipes. All you need is the adapter.

Scroll down a bit & there are all kinds of flavours of adapters. You might be able to find something like them locally, but it usually takes some searching in a specialty hardware or plumbing shop!
