Except in summer, faucets sputter and spit. What could be letting air into the system?
In this case the setup is in the Northeast USA, New York State, with a pressure bladder tank, and shallow well. It looks like the image below. The pipes leading up are the distribution. The pipes into the wall are distribution and pump inlet. The pump does not appear to short cycle.
I found a possible answer, but it does not explain the winter/summer dichotomy.
If the pump does not short cycle, that means the bladder in the tank is OK, assuming you have seldom needed to refill it with air.
A shallow well could be the root of your problem. Especially if summer coincides with your rainy season. At the beginning of last winter, along with most of the rest of it, the Northeast USA was in a drought:
Upgrading our summer home, we sunk two additional well-points (with a jackhammer), as the pump we got to handle our four new bathrooms was to powerful for the existing single well-point. Evening being located five feet above, and 200' away from a lake we had supply problems; it would cavitate/aerate.
Does your faucet spit and sputter? -JohnDee.com, people suggesting low water table or bad pump seals. Possibly yours fail with a drop in incoming temperature.
