First tank lasted 5+ years
I purchased this tank in mid-2018 and after 5 years noticed it had developed a small leak which caused some rust water to drip onto the bottom of my cabinet. I've had other tanks which didn't last 2 years before the bladder burst, so to get 5 years out of the tank was a plusI just purchased this again last week to replace the leaking tank and installation couldn't have been easier. I literally took the hose from the old tank, installed the hose into the new tank and installation was done.I did take the extra steps to sanitize the new tank before re-installing the filters and I ran 4-5 tanks of water through it to assure any preservatives in the tank bladder were removed as it can cause a bad taste. I had also replaced the membrane filter, which recommends to do this as wellThe tank was pre-charged with an appropriate amount of pressure and the tank is working as expected. The water is clear, clean and tastes good!

The water tastes great!
The tank was very easy to install. I discarded the old tank and replaced with the new tank. I placed the plastic hose into the new tank and the tank started to fill. The only down side is after you use filtered water, you will hear the sound of water dripping as the tank is refilling. It's just the nature of my particular reverse osmosis system. But the water does taste great.

100 psi is a lie but the tank works as expected for ROI system
Amazon has some really wild claims of 100 psi, it's actually preset to 7 PSI per the paperwork in the box, don't change the pressure whatever happens, you will break this tank...Anyways, it does work at expected, but only time will tell the length of life!
