baseboard heating - hearing water sloshing around

elfie

hearing water sloshing around the pipes near the boiler and in the base board pipes



is this air in the pipes?



how do I get rid of the air? could it be another problems (water was replaced in system after the pressure relief valve was replaced)



thanks

Sounds like

air.  It could have entered the system when the relief valve was replaced.  There should be some kind of air elimination device on your system (automatic air vent, Spirovent, etc.); the trick is to get the air to migrate to that device.  Do you have someone that services your boiler?

auto air vent

i located the auto air vent above the expansion tank and above an air scoop



i pressed it and it release some air



it doesnt seem to be doing it automatically  - should it??



thanks

air in system

It is air in the system.  What is your water pressure at??? It should be at 12 PSI.

lack of water pressure will cause the system to trap air.

air / water pressure ??

system  pressure  when cold & full should be  15 psi minimum....when hot  higher...maybe  as much  as   24 psi...//   1156...extrol tank...& gauge  should  all be changed  with relief  valve...//   that  eliminates   "free"   call backs   two..or 3 days  after  relief  changed...
