|In response to Re: Plumming Noise|
: Recently, over several weeks we have been hearing the water run through the pipes in the house. We have a high ranch with baseboard heating. The noise is not the poping that I read some people are having trouble with but rather the water running through the pipes throughtout the house. We have been here over 10 years and have never heard this before now. Any idea what could be causing this to suddenly happen and what would you recommend as a solution?
Air in the System causes these sounds, before you decide to bleed the air out check the gauge on the boiler for your cold fill pressure (hydrostatic) and look at the actual pressure.
The pressure reading should be 12-15 PSI with an attitude reading hovering around 28 ft minimum.
If you know where to located the fast fill feature on your boiler automatic feeder you can increase the pressure to around 28 PSI (boiler off) and then bleed out the air from either the bleeder valves or the valve set up that should be located for each zone.
You may also want to consider installing a quality air vent like a Hoffman # 75.
When fast filing these systems you should isolate the expansion tank THEN after all the air is out open the isolation valve to this tank turn the boiler on and monitor the actual working pressure for at least two cycles and keep clear of the PRV WHICH is now a good time to have tested as your there any way.
