Question: is the tank initially pressurized to 5-7psi or do i have to do that initially?  thanks.
Document: Our system is 5 years old, the filters have been changed accordingly, but the water pressure had dropped to almost dripping...My dad told me we needed to order a new tank, and this one was half the price of the one he ordered from the Watts website. I got the new tank in a week, and easily switched it out myself. Our RO system is like new again. Thanks!
I bought this to replace the tank on my WHER12 RO water filter system. My old tank was putting out about 6 cups (in my 12 cup coffee pot) before slowing down to a trickle. This tank arrived with the bladder pressurized to 10 psi and the fitting was an exact fit for my old WHER12 system. The install took maybe 5 minutes total. Once the tank was filled, I can now fill three 12-cup coffee pots back-to-back (36 cups).
My RO water system would only give a cup or so of water and slow way down. With the new tank, I can get more than a gallon before it gets slow. Thanks
I am very happy to have purchase this water storage tank to replace the old one.The delivery is quick and upon receipt of this item I installed and replace the old one immediately. Now the water is running fast and good enough for the water supply for the whole family consumption. No more wasting time to collect water as with the old tank.Thanks to the Amazon
Doubled my capacity with this. I did have to charge it to 7psi but it works great. I just put a T in and I'm gtg. Very happy.
This tank comes pressurized and ready to go. I switched the ball valve from the old tank to the new one (don't forget the teflon tape!) and reconnected the line (Quick Connect in my case). My system was up and running great after the usual "fill time".I guess only time will tell how long this tank lasts.Update: July 4, 2013...Still Working Great!
The original GE reverse osmosis storage tank finally died after 6+ years. Initially, I wasn't sure if it is compatible --- it is.Just unscrew the tank connector fitting from the old and screw it on the new tank. That's it.The RO system is now as good as new.
I started out with a 2.5 Gallon tank but it failed after 2yrs. I saw i had the space for a bigger tank and ordered one. Easy hook up and flush.
Ordered 2 tanks. One tank failed right away. The other one works but water still tastes like rubber after 5-6 fill-ups.
This replacement tank looks just like my old one. So far it's fine and I will give it a 5, but the issue I have with all these is that the bladder breaks after a couple years. Really wish they'd last longer.
Answer: yes
