"I had a new hot water heater installed, and shortly after that, it
would discharge water."

why?
1) pressure
2) temp
3) faulty T&P

How are you going to tell if the discharge is either a faulty T&P or
due to pressure, you can't without a gauge.

How are you going to tell if the pressure is from a bad PRV, you can't
without a gauge.

You can watch the spikes on a gauge and even verify thermal expansion
is happening with a gauge.

Only an idiot would come to a conclusion without facts, at the expense
of a homeowner.
