RO/DI Water Pressure
What is a good inexpensive way to test your household water pressure? What is a good pressure to shoot for for an RO/DI unit?

$9. That's about what you'd spend at Hdepot for a gauge that connects to your hose faucet outside. It screws on by hand, turn the faucet to on, read pressure. 60 working pounds is adequate. You might need around 75PSI to have 60 as your working pressure. It isn't necessarily how much static pressure you have but how much of a loss do you experience when you run the unit. My last place had nearly 130PSI during the day. Remember that at 2:00am when everyone goes to sleep that your static can increase 2-20PSI.

Ain't that the truth.
I run at about 70psi on my R/O when everyone's asleep.
If I run it during the day when water is used it runs at about 40psi.
I overflowed the barrel the first time because I started it during the day and found out how much pressure difference there could be.
