I recently bought this replacement tank for my whirlpool reverse osmosis because all of the whirlpools would only last about two years in a tank would begin to lick. Just wooden hole pressure.This replacement tank from Amazon is a fantastic well well-made TANK with a whole lot less money.I picked up the extended warranty probably won’t need it.If you need one, I recommend one from Amazon.

I replaced my Nimbus Watermaker 5 tank. It was 11 years old and wasn't doing the job. After filling a water glass, the flow slowed to a trickle. This was very easy to install. The included 1/4" valve was too small, so I just used my old valve. Now I have great flow to all three RO dispensers. Make sure you verify the pressure is 6-7 lbs before you install.
