"My only concern is that I have to purchase a new tank every 2 years because the internal bladder Leakes and my 4 gal tank only provides me with 1 gal of water. These tanks used to last a lot longer. Yes, I have been using this product for some time. This alone is why I rate the tank at 4 stars. Works great but does not last."
"My water was not putting out as much as it used to and changed my tank and it back to normal."
"Added this as a second tank. Works perfectly. Now I have sufficient water running to my icemaker and fridge."
"Our original tank must have been defective because our water pressure and sustained flow are 10 times better than ever before. I just wish the tank valve with the tank was included with the tank purchase because we had to wait a bit to install the new tank. Luckily the valve arrived quickly so the delay wasn’t as bad."
"The tank work perfectly, I'm very happy with it."
"The products I received for you for my home osmosis system works great. Thanks"
"The tank came - no instructions on how to exchange the tank - no teflon tape. This used to be part of the package. A little disappointing."
"I suggest that before shipment of this tank, APEC makes sure to include a washer/gasket for the water outlet fitting at the top of the tank. Once I received this tank, disconnected the old/original tank and reconnected the white plastic valve fitting to the threaded nipple at the top of the new tank, water immediately began leaking down the sides of the tank! I carefully tried tightening the fitting (not wanting to strip the plastic threads) and this helped minimize the leakage; but not stop it entirely. An appropriately sized washer could obviate this problem."
"The new tank is great…!!!. It is so wonderful to have good pressure again for our filter system…. Thank you…"
"I’ve written earlier about how we love the APEC WATER FILTRATION SYSTEM. It meets an exceeds our expectations for delivering delicious, chemical free water. It is a superlative product, and we couldn’t imagine our life without it."
