Agreed.
You should really consider a unit that has a booster pump. With the booster pump you get water faster with waaaaay less waste. Also the booster pump will extend the life for the filters. |

If your pressure is good, I would suggest first trying to get your waste to product ratio down to around 3:1 or so, then a permeate pump and a booster pump as the last option.

calgary. I have NO CLUE who/where to find the info about water quality as I wanted to know about phosphate levels and a few other tidbits. Whoever I called had no clue what I was talking about both in Airdrie and in Calgary. Annnnd I have no clue how to find out/test my water pressure/TDS/temp in my own home. cold water comes out and turns hot in the tank is as far as my awesome home owner skills go. Hubby is away and I don't think he would be able to tell me how to go about testing or even adjusting the pressure. I am sure the pressure is not a problem in our house since the water coming out of the tap is pretty strong (for sure compared to my parents taps). Would you be able to recommend where I can get info about city of calgary water? And how to find out the rest of that info? Much appreciated!! |

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. http://www.vertexaquaristik.com/Prod...ek100RODI.aspx |
