Back again! So far I've gone two for two with resolving issues here and really appreciated that, so thought I'd bend your ear again.....
I have a deep well (drilled August/2011) supplying water to my house at 300 feet. 5" casing. Slot/gauge 25 of 60' between 300 feet and 240 feet. The Grundfos 1 HP pump sits at 240 feet. The well provided 12 GPM after 12 hours of constant pumping during verification, and is an excellent quality well according to the driller.
As I live on a lake, normally, I use a different shallow well pump to draw water out of the lake to water my lawn. With freezing temps now here in Minnesota, I was forced to winterize my lake pump a week ago, but as the weather was nice yet this week, I wanted to water my new sod one last time so I watered with my deep well pump.
Important to note: This was the first time watering with my deep well pump. So while watering, the pump was running continually (except for cycling of course because of pressure switch) for a few hours.
I noticed that there was a little air getting in the line. The faucet lines I was using are pure hard water lines; don't go through any of my plumbing. I didn't hear a lot of air.....it might be fine for a couple of minutes, then a short shot of air or maybe two, then no air for a while, then repeat. At no time, did I see any reduction in volume of water being provided.
Since moving into the house about a year ago, I have never noticed any air in the line but I live alone and water demand is minimal. Yesterday was the FIRST time that I had put a constant heavy demand on my well since I moved in.
I did talk to the guy who drilled the well this morning and he said that he does not feel that it is a problem with the well itself. He said he was unsure exactly where the air might be getting in, but said if I don't notice any air when I go back to my "regular water demand", then it isn't worth chasing and not to worry about. it. He specifically said though that he thinks the well is fine.
Another thing to note but probably not in play here, is that I have an additional check valve installed in the house where the line comes in which was put there because I was seeing a slow 3-15 psi drop per hour in water pressure not long after the well was drilled; the driller felt that the check valve on the pump itself was the culprit for that, and instead of pulling up 240 feet of pipe, the check valve inside the house was installed and resolved the pressure loss.
I did have a couple of short shots of air this morning when I showered, but attribute that to a little air left in the 240 feet of casing. Thought I'd see if you guys agreed with the driller or have any other ideas. As I only work the well hard once or twice a year, maybe I should just consider this a "characteristic" more than an actual issue??
Thanks for your thoughts......
