We have had water pressure problems for a couple years like if I was washing clothes and then turned on a sink the water would be a very small stream but when the washer kicks off it would practically blow the bottom of the sink out. Then about 6 months ago we started having "white water" like if you got a glass of water it would look milky but clear up.then about 3 weeks ago my son was in the shower and he started yelling cause the water cut off he turned the shower off waited a few minutes and it came back on but we had been asleep so no one had been using the water and then it didn't happen again for about a week then I was doing the smallest load of laundry and it wouldn't even fill up before it cut off and we had been gone all day just got home so no one had been using the water and it has happened several times there is also a lot of air in the lines when it comes back on like when the power goes out then comes back on but I noticed that if I catch it before it totally stops and turn off the washer for a minute or so then turn it back on it will fill up. People have told us several things it could be a busted pipe somewhere, the pressure tank, the pressure switch or well going dry what should we try 1st or should we call a plumber
