    Better price than in the store. I used a 12 Volt auto tire pump to put 70 lbs of pressure in it. Local water dept and a plumber said the pressure here is 60 - 70, so I didn't buy a water pressure gauge just to use one time. I didn't think about this at the time, but if you don't know your exact local pressure, one could over inflate it (maybe 80 lbs, and then after it is installed and the water turned on again, one could use a tire gauge to check the pressure (it's like a tire valve on top of the tank). It will probably be high, so one can just let some out, until it's at 0. (The water pressure should roughly equal the pre-installed inflated pressure).

    Product is good exact same one like I am replacing,at this time it is difficult to rate this item , it has to be in service for a long time before it can be rated. At this time it's just a painted can with an air bladder inside. How can one at this time rate this item, five years from now if it's still functioning , then I can rate it. But not at this time, at this time all I can say it looks nice, but it does have to dents in it, which I do not think will effect it's performance..

    Expansion Tank
    This expansion tank was easy to install and worked as described. TP valve was dumping hot water into the drain. That stopped when the expansion tank was installed.

    The tank was pre-charged, and match the water pressure of my property. Easy and quick to install.

    Works as intended.
    Works as intended. I learnt these were needed when you have a water meter as there is no other room for water expansion than your heather tank. Make sure you put at least 8 layers of Teflon tape on the threads or you will not get a proper seal.

    Design and function matched engineered requirements. Installation instructions were both easy to understand and accomplish. Good value for the money. The only remaining question is how long the tank will last in a mildly corrosive water environment. The previous tank lasted 25 years before rust-through.

    Inexpensive but solid product.
    Relatively inexpensive and is working well. I just replaced the two that were on the original hot water tanks. Installation was easy, but I learned from the first one that it becomes even easier if you leave the faucet open on the hot water side and then inject air into the one you are removing. That way you displace the water and the tank you are removing is not filled with water.
