How do you check pressure on Expansion Tank when Gauge only goes to 60 PSI

[Themus]

I have to replace my 20 year old water heater (died two days after its 20th birthday, 2005 of this month. Must have been mad I forgot its special day). The expansion tank I discovered is also history. Been 20 years, so I am rusty (no pun intended) on some of this from the first time I set it up.

My home water pressure is 78 psi and so I am supposed to set the expansion tank to 78 psi.

My gauge, like almost all that I am finding, only goes up to 60 psi. The pressure tank has that needle value like a bicycle tire.

What are most people using or buying to check these tanks when they go over 60 psi?

You can easily get a tire pressure gauge that goes to 80 or more.
https://www.walmart.com/ip/Slime-Ti...Silver-8-5-New-Multiple-Makes-2016-a/16782760 is one example.

Also, a truck stop or a tire shop is likely to have one for you.

You can also carry your tank to your local tire store, and ask them to fill it for you.

Thank you. Yes, I don't know how I missed them in my search yesterday. Fresh mind and start of a new day and I found many. Picked one up at HD that did the trick!
