Thought I was upgrading.....
So I recently bought the 150gpd membrane to replace a 75gpd membrane. The time to make water was taking to long for me. This was a mistake. The new membrane AFTER the DI is kicking out 7-10 TDS(As a side note- I replaced all the media when I initially purchased the 150gpd membrane). The 75gpd membrane was 0 TDS after the DI. The even more aggravating part was when I contacted BRS they were very helpful in trying to identify the issue. Re-seating the membrane did not work so then they asked me if I had a flow restrictor on. As it turns out, I did have one from when I purchased the 75gpd membrane to ensure I had the right pressure going through the system. At the time it was marketed to me as being rated for a 75gpd membrane. So after explaining this they told me I needed the one rated for the 150gpd membrane. So I order it....get it in the mail. Its IDENTICAL to the one I already have....and guess what....the TDS after DI is still measuring 7-10. The TDS coming in is just under 200 before running through the RO/DI system. So I am not convinced the load is to heavy and because of the fact that the 75gpd membrane handled the load without issue.
SO do I have a bad membrane or does the 150gpd need more restriction than the capillary 800ml one sold to me initially as a 75gpd restrictor and then resold to me a second time as one rated for 150gpd membrane? Do i go back to taking half a day to make water with the 75gpd membrane?
The worst part of this experience is that BRS is my go to spot for things.....NEVER had a problem with shipping or any other product. Now I dont know what to do? Call back and get something else shipped to me, wait for it to arrive, and hope it fixes the issue? I just want to know why I am not getting 0TDS after my DI resin. Feeling frustrated :-/
Performance is 5 times worse than the 75 GPD
I replaced the 75 GPD membranes on my 6 stage BRS + Water Saver system with these 150 GPD membranes. I was getting 3-6 TDS from the 75 GPD membranes. After the replacement and letting it run for well over an hour, I'm still getting 15 TDS coming out of the RO system. This is just going to kill the DI resin. So much for this being a good investment.
Best Bang For The Buck!
I have been using this membrane for over a year and get 1 TDS on the product water, before the DI resin.
I split mine off the washing machine valves, both hot & cold, using a regular garden hose splitter. I then used a "Y" hose meant for washing machines to combine both the hot & cold into 1 output. So 1 leg of the hot & cold goes to the washing machine and the other leg of each splitter is combined into 1 output that connects to a short, food grade garden hose. That connects to the RO/DI system.
I run the GE premium .6 micron sediment filter with a 1 micron carbon block, both sold here on BRS.
My TDS from the tap varies between 35 and 80, but comes out of the membrane at 1 or 0. I have 80 psi going into the membrane with no booster pump and fresh pre-filters. The key is to flush the membrane (mostly before) you make water. If you have the 3-way tds probes connected inline you can watch the tds get lower and lower while flushing. Obviously it's good to flush afterwards, but I use one of the auto shutoff kits to prevent over filling and that usually stops the water before I get to it. I'd rather that than ANOTHER flood.
But BRS sells a flow restrictor with a valve knob so you can open up the flow just by turning the knob. If you're new to RO/DI setups I would HIGHLY recommend installing the auto shutoff kit.
Also, just to let some people know, you CANNOT run these membranes without carbon before it. Chlorine and Chloramine will kill the membrane. I made that mistake in the beginning when I was rinsing a new membrane and thought I'd bypass the pre-filters. That's a no-no.
This membrane is great if you have the pressure. There's no doubt that I am getting more than 150gpd. That's at 65psi. So at 80psi this membrane flows.
it works like it suppose to. you do like mention previous post you need a boster pump
Number 1 in the industry
I have had my last one for 10 years. Decided to replace this one because it was starting to leak. As long as you run water though it before and after you make water it should keep 10+ years! BRS is great at having products like this at hand that they will ship that day or next.
I purchased this to replace my old one and it has surpassed my expectations! This is a great product!
Works as it should, no problems installing, no leaks.
it works well
it works very well.
Insane in the membrane
Wow, this thing puts out a nice stream of high quality H20! Just make sure you have the line pressure to run it. High rejection rate membrane showing 0 TDS out the product line.
Great Membrane for Great Price
This is the first time that I have ever brought this product, as I usually have a 100 GPD Membrane for my tank.
After changing, the water is clear & the algae problem i am having is clearing up nicely, there is no new growth. My RO/DI water was reading extremely high & now it is back to zero ppm.
This membrane is also at a very good price, as others I have priced are much higher. I will defiantly be buying this product again.
