– RO Water Filtration System Expansion Tank – 2 Gallon Capacity Water Tank – Compact Reverse Osmosis Water Storage Pressure Tank with Free 1/4" Tank Ball Valve

It’s a long run from my RO filters to the tap on my sink and another on my fridge, so the water pressure wasn’t very good. I added this little tank and mounted it out of the way, up and under the sink, and what a huge difference that made in the pressure! I can now fill a pan or water pitcher in matter of seconds! (I also added a permeate pump but I’m pretty sure the credit for improvement goes to this tank below the tap!)

I had a five gallon tank before and I needed back some space so I got this two gallon. It's pretty much perfect for storing Ro water that is made by my RoDi filter system. The Tank is small and neat and feels well built. The water from my Ro Filter is used to fill the Tank and then the pressurized water is then diverted to my Di Resin when a solenoid is activated by my top off sensor in the tank. This happens when my controllers level sensor indicates a low water level in the sump.I am very happy with this tank and highly recommend it.

I installed this in my RV to keep the water pump from cycling on/off so often. It was simple to install and does the job. My only complaint is that for an RV installation, there is no simple way to secure the tank to the floor so that it doesn't bounce around while traveling. I had to rig up some straps and screw them to the floor. For a home use, this wouldn't be an issue.

Easy install! Works great

this product is being used on a RV R/O water system.

Perfect. Exactly what I wanted. Live alone with dog. smaller tank fits my needs way better than the huge tank that came with it. Same good quality excellent quality fitting with shark bite. Plug and play.

This tank is half the size but you don't lose performance! However you gain space under your sink. I would buy again, and highly recommend

Comes well packaged with base and the shut-off valve which is much better quality than most of them The instructions are in English , comprehendible and they are helpful Most importantly the tank seems well made and works just fine

had to go find a proper threaded valve from a plumbing store

Cheap metal
