It works

The connector part on the new tank is shorter than the original version, but I managed to install it without any leaking, so I guess it's OK.

Our third tank. Both the original tank and first replacement lasted 5 to 6 years each. Nothing glamorous. It does the job and is easy to swap out.

The tank worked just fine.

The tank worked just fine. The original one lasted around 4 years. I guess that's normal. Either way it's cheaper than bottled water and it omits all the wasted plastic. The people at Apec were very helpful in helping us determine why the original one was just trickling. Thank you

Replacement tank is perfect

So glad I was able to replace my old (original) tank, which was starting to have bladder problems and kept just dumping water into the drain line. Beautifully packaged, easy to replace, peace of mind! There is a protocol to repressurize the old tank, so I may try that with the old tank as a back-up, but the replacement tank was available at a sale price and is worry-free.

This new tank was just

This new tank was just what I needed to restore the water flow to its full capacity. The old tank lasted for many years. The old tank itself still looks like new, but the diaphragm inside of the tank must have broken. Thank you.
