Works great. Inlet was smaller than expected but easily remedied ...
Works great. Inlet was smaller than expected but easily remedied with a reduced. The seam around the middle is big and conflicted with my support bracket, but that's ok.

First time install, leaking water from the shell.

junk
The item description states 3/4 inch fitting but it is only 1/2 inch. I like to rely on Amazom to provide accurate information. This error caused me to take time during Covid-19 to go to the hardware store for a reducer. The cost was not the issue. The effort involved was. The product was well made and works as it should. No complaints there.UPDATE: failed after just a few monthe...filled with water and became useless

Get a pressure gauge first and still only lasted 4 years
Update: lasted 4 years. Rusting and leaking near the inlet. Ordered a stainless steel for a little more. Arrives hopefully in time.Original: They are precharged to 12psi and I installed upside down (threads down) and included a threaded shutoff. I installed without having a gauge for my water. My system's water pressure turned out to vary between 38 and 50psi. 50psi is only 10psi below this tank's maximum. It's on a Solar hot water system. I had to remove it after turning the valve off and it was like a water cannon. Pretty exciting. Charged to 40psi and reinstalled. I give it 4 stars because of its 60psi rating. My 400 year old boiler plumber installs upside down because they last longer and more capacity. The ball valve has already saved me from refilling the system once. I'm still not exactly sure what pressure I should have charged it to given my range of water pressures. I went with the lower end so as to not stress the bladder more.

What can I say? It's a pressure tank.
I picked this up when building the manifold for my floor heating system. It appears to be well built with clean threads on the attachment point. It is now installed and helping relieve pressure build up in my system. I'm running about 25lbs of pressure on the system and it appears to be handling it with no problem.

Not 3/4" mip. Poorly packed.
The tank has a 1/2" mip fitting, not a 3/4" mip fitting as listed. The replacement tank also has a 1/2" mip fitting, so perhaps all these tanks are 1/2". The packing is minimal, just the tank rattling around in a cardboard box, so there is potential for damage to the pipe fitting or the air bladder pressure fitting.

Seam leak
Product started leaking around seam within just a few days after install. Don’t waste your money.
