What is wrong if after flushing the toilet the water supply to the toilet spits out air only but if you turn off the water valve for a couple minutes then water fills the tank?

poor water pressure, blocked shut off valve, It may be that you

have air suspend in your water. It is common for water treatment

plants to airate the water to remove things or to oxidize things

like iron so that it can be removed. Also, cavition from a pump or

turbulence in a water line can create air in water. One thing you

can look for is to fill a clear glass with water and look for a

white look to it and for it to clear up after a short time. Use a

spigot that does not have an airator on it. You could put in an air

relief value in a high spot or at the top of a short T before the

problem area to bleed off the air. Some times an air relief value

will also bleed off some water with the air, so you may need to put

in an area that will drain or not do any damage. Waterman
