"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 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."
"The first 4 gallon tank that I purchased with my under sink water system from Apex has lasted a decade. I noticed that it was losing pressure so I used my air compressor to add some air and so far it is still holding up, but I purchased a second tank so it would be ready to go when my first tank finally gives up the ghost."
"Works the old one just didn’t have any volume. Got the shutoff valve I was told I needed. Turns out I didn't oh well"
"Everything worked out great…after I actually listened to the APEC customer service representative and wrapped the top in plumbers tape before screwing in the cap."
"Replacement for our previous 15 year old tank on our APEC system. Output water pressure and flow is back to normal. An exact APEC replacement meant that everything fit properly and only took 15 minutes to swap out."
"Great purchase once again. 6 years going strong. 💪"
