"Sales team was very helpful with the selection of this tank. Ordered online and process was easy. Received notifications throughout the process. Received the tank in good condition and when I was told we would receive it. Would recommend ESP Water to anyone looking for these products."
"I had a problem with my ro system. Their technician diagnosed the problem correctly and had the part on ups before we hung up. The part fit perfectly and solved the problem. Any more problems with my system and especially will be the first and only company I will call."
"First time ordering. Website easy to navigate. Items arrived in a timely manner when promised. Awesome experience."
"After many years, my RO tank needed replacement, no longer holding the needed air pressure. . . found this replacement tank and installed it easily! My system is restored with good water pressure. Highly recommend."
"RO-122 RO Water Storage Pressure Tank 3.2 Gallon is installed and working fine."
"Solved problem"
"Hard to give an exciting review of a water tank, but it was an easy install and is operating. ESP is the ONLY company that stocks my RO system filters and parts so thank you!"
"Everything arrived in good order."
"Replaced the old tank, which wasn't delivering any water, with a new smaller 2 gallon tank. Fits much nicer under the kitchen sink then the older 3 ga. tank. Came fast, was easy to install and is working perfectly. It does take a while for the tank to bleed all the air out, fill and stabilize."
"The individual at ESP Water Products that I spoke to a couple times on the phone patiently helping me purchase an item and then helping me with a return. I wish I remembered his name. Your process of handling returns was personal as well. Thank you for the excellent customer experience, Peter"
Q:
Is the RO-122 a 3.2-gallon usable-water tank?
A:
The 3.2-gallon figure is total internal volume, not the amount delivered at the faucet. Typical drawdown is about 2.2 to 2.5 gallons and varies with feed pressure, tank precharge and the RO system's shutoff setting.
Q:
What connection does the PAE TKE-2200W use?
A:
The tank has a 1/4-inch male threaded stainless-steel water connection. A compatible tank shutoff valve is normally installed between this fitting and the RO tubing.
Q:
What should the empty-tank air pressure be?
A:
A typical factory precharge is about 5 to 7 psi with the water side completely empty. Always measure and adjust precharge only after shutting off the feed and draining all water from the tank.
Q:
Will the RO-122 fit under a kitchen sink?
A:
It is a compact residential RO tank approximately 14.6 inches high by 9.8 inches in diameter. Allow extra room above the tank for the valve and tubing without kinks.
Q:
Which systems can use the TKE-2200W tank?
A:
It is used as an RO-122 replacement tank and is cataloged for compatible systems including the Microline TFC-400-ESP. It can also serve other standard under-sink RO systems that match the capacity, connection and pressure requirements.
Q:
Why does my RO tank hold less water than before?
A:
Incorrect precharge, low feed pressure, a restricted membrane or filters, or a failing internal diaphragm can reduce drawdown. Check precharge with the tank empty before deciding the tank must be replaced.
