In response to Re: Air in Line/Pressure Tank?
: Hi, all!

: I had to replace the pump that pulls water into the house from the spring. After doing so, it seemed that, whenever the water was first turned on (hot or cold line), the water from the faucet would "spurt" for a while and then resume a smooth flow. I have observed the pressure tank "banging" during this time. Upon further observation, it seems that this occurs when the pressure in the system drops to the point where the pump kicks back on to refill the tank.

: This is the same tank that was on the system. I reconnected it to the system while replacing the pump. I think it was reconnected correctly, but wonder if I didn't do something right and there is a problem either with the pressure settings (it empties too far before starting the pump), with the initial refill of the system (i.e., when I started the new pump for the first time) or with the tank itself.

: Any thoughts or suggestions would be welcome.

: Thanks in advance,

To get the pump to come on prior to all the water exiting the tank, simply raise the water pressure a pound or two. You do that by tightenting the tallest screw's nut in the pressure switch. One turn usually equals 2 psi. If this doesn't fix the problem, you may have a leaking foot/check valve and it is drawing air into the pipe to the pump; or there's a leak in the plumbing to the pump. Or you might have a blockage at the water inlet in the spring. I suspect the switch setting needs to be increased, or less air in the tank for the setting you have now. It's best to increase the water pressure than decrease the air pressure.
