What pressure should I be running? Dripping Relief valve

mine are 30psi your pressure readings is that at full burn? cause I had mine a little high say 15psi and with a good hot burn it started to drip I just lowered my pressure and al is well.

put a bucket under it and open the lever and let some water pass. see if you get any thing besides just water. You might have some scale, rust, flux whatever and that might have gotten under the rubber seal. After you flush it a little, open and close it a few times and maybe that will dislodge whatever is on the seal.

You should run at enough pressure to get water up to your highest radiator/convector air relief elevation in the house when the temp is the lowest it will go in the boiler. Anything more is really unnecessary unless you are so hot as to boil water, which isn't a good idea. 12 # works for me in my 2 story home w/ the boiler in the basement.

At full burn it is about 12. It is a 30 valve on there.
I think I snagged the arm on the valve with my jacket ( I was cleaning behind stove) and that is when it started to drip.
I then opened it up and shut it but it still has a few drips overnight.

I had one that leaked for better than a year after I bumped it . Try burping it a few times to clean it out let it a few days if it still drips , do it again and so on
as far as your pressure 12# should be fine and certainly not cause that to leak . Past experience mine use to start dripping at 26 #
As far as the valve , no worries probably still works fine , On the dripping note (PITA ),
If it is still dripping at the end of the heating season replace it .
Special note here
If you can burp this when your system is cool , because if hot you will reduce system pressure , not a real problem but by reducing system pressure you could possibly induce air into your system .

At least its a good night in Wisconsin for keeping beer cold in au natural

Here is a good explanation of how to determine the pressure that you need in your boiler when it is at the lowest operating temperature.

check your expansion tank. see if its water logged, if you don't have one, you should consider adding one.
the tanks are usually precharged for 12 psi. In order to check the pressure, you have to remove it from the system and check the precharge.
