Venting Like a Hissing Snake
Good day all!
Need the pros here. I have a Utica that is about 3 yrs old. Installed it myself and believe all the piping is correct as I followed the installation manual and read the tips here.
However, as of late, there are a couple of rads that are hissing loudly on the second floor. One in particular hisses, clangs and then stops; 10 seconds later it does it again. I dont believe it is water hammer as I checked with a level and it is sloped half a bubble to the valve. The Hoffman 40 is new and started after I replaced the old POS vent.
One thing I also have done; the mains are 37 feet long with 2.5" dia pipe. Venting was only done with a Hoffman 75. I had three gorton 1's laying around so I antlered the hoffman with the three gortons on the existing 3/4" elbow.
Pressuretrol is set to .5 in / 2 out. Confirmed it on the gauge numerous times.
My feeling is that I am still venting the mains thru the radiator. Dont have the problem on all of them just this one. Note that the boiler is overfired (80k btu vs 67k required based on my EDR calculations; I got a deal I could not refuse on the new boiler...)
Any thoughts here?
One thing to note: the mains were NOT insulated so I insulated the NBP and then the main about 7 feet out from the boiler. Wife will not let me insulate the balance of the main due to asthetics of our basement- "Deal with it!" is what I got.
I have become obsessed with this issue because I want to sleep at night and not hear the snakes!
Thanks in advance,
"Hey, it looks good on you though..."
