Would Not Recommendnever got delivered and it is labeled with correct address maybe driver is new but I want my money back or new tank asap
Not as complete as the last time I purchased it.
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.

Heavy, no handles, and it
Heavy, no handles, and it keeps failing! Why is it so hard to design a tank that doesn't fail in few years?

Solved the pressure issue, but leaks at top!
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 ...

I’ve written earlier about how
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.

First tank lasted 10 years
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.
