membrane exhausted?

[neoh]

08 phosphates in water? That's pretty high! Suggested replacement is every 3-5 years, depending on usage. Have you tried testing it right out of the tap? I should check mine, too.

I will test out of tap. But I'. Going to order new membrane today

Do you flush your membrane on a regular basis? Membrane should last more than 2 years.

Not sure how to flush. Honestly thought it did it itself. It's a vertex puretek

Not sure about that one, but the better ones have flush valves for both the membrane (extends the life of the membrane) and DI, and also an ASOV to waste less water, and also extend the life of your membrane, as well as your prefilters. Here is some info on the one I have. Works really well.

Just looked and it does its own backflush. I bought used so it could be three or so years old.
Also it made 400g a month for the first year I had it and 160g a month since. If I remember . Was told that making small amounts of water is harder on the membrane

Have heard that, too. Not sure if it is true. Here is my trouble shooting guide. Maybe it will give you some ideas on yours. My membrane is probably 6 years old, and still good. I bought the unit used 3 years ago, and the guy said it was 3 years old. So this one certainly lasts a long time.

New membrane is never a bad idea, but it would be to your advantage to find out more about how to use your specific system, particularly the flush feature, as that's a major factor in aiding a longer life for your membrane. Must be some instructions available from a company like Vertex? Would also help if you provided more details on your unit other than Vertex Puratek. How many stages, including pre filters & carbon etc? What micron value are the prefilters & how often do you change those?

Aside from that, depending on your source water TDS, your membrane may last longer than other people's or not. Folks on the west coast generally have very soft, low TDS tap water to start with so their membranes can last a very long time because they're not dealing with 100 - 200 or even higher TDS tap water. Nevertheless, even with an average 180 TDS tap water here, I'm still on my first membrane after 5 years of use. I manually flush before & after each run & I generally make a minimum of 14 gallons of water.

I've found the Buckeye Field Supply (now Buckeye Hydro) site a great source of info as well. Never steered me wrong & they're happy to help even without making a sale. Link to their FAQ page:

Some great info there on tools such as pressure gauges to aid in determining when it's time to change various filter stages, including membrane.
