Incorrect installation is a common problem. Other factors include switching off the mains and switching them back on again while keeping the taps closed. You may also have a faulty vacuum breaker
Install a spirovent
air in water lines usally accur when the water in turned off for some reason,just let the water run in a tub for 5 min. air in water lines that make your pipe rumble, you need air chamber installed. its called water hammer turn of all hot faucets and run till air stops coming out and steady stream of water comes out.
Cold water lines may have more insulation than hot water lines, otherwise they should both freeze unless there is some agent in the water.
This is probably a pressure imbalance problem or you have air in the lines. see the related video link provided.
== Answer== I don't think so, but get the air out of lines to make sure.
Hot air.
Steam heat normal Hot water perhaps air in lines and need to be purged
Yes, a bad pressure tank can cause air to enter the water lines, leading to air bubbles in the water supply.
Usually blowing only hot air means the water is not covering the pads. This could be abad water pump, clogged pump inlet, low water level or clogged distribution lines where they drip water on the pads. It is possible the pads are also caked with mineral deposits and no air can get through. Take the cover off and see what the water is and is not doing.
Install hammer arrestors at the highest point of the water lines.
No. If you have hot water heat, you also have a separate air handler for the AC to circulate the air.
Air can get into water lines due to a few reasons, such as leaks in the pipes, changes in water pressure, or air trapped in the system during installation. This air can cause sputtering or spurting from faucets and affect water flow.
