pressure gauge on hot water heat too high

[Fred Mertz]

I've noticed water dripping from the pressure relief drain on the Utica boiler. The pressure gauge reads 25 to nearly 30 psi. Can I adjust the pressure down with the adjusting screw on top of the B&G valve?
Thanks

not a boiler expert, but generally speaking, yes...typically, unscrewing reduces.

You are correct......I googled it.https://api.ferguson.com/dar-step-service/Query?USE_TYPE=INSTALLATION&PRODUCT_ID=1101

Check the expansion tank and make sure it's not waterlogged first.

GReynolds is correct and while you’re at it replace that relief valve with a fresh one if it has any age on it.
