Whether you just had a well installed or you simply purchased a property with an existing well, taking care of it properly is vital to ensure you have an abundant supply of fresh water. Although maintenance may seem pretty straightforward, there are some mistakes you most definitely want to avoid so you don't have any major problems.
#1: Covering up the well head
The well head or access point is typically above ground in a place that is relatively easy to access. If it happens to be placed in the middle of the yard or really close to the house, you may not be too fond of its strictly utilitarian appearance. Fight the temptation to cover it up with mulch or soil. If the seal ever loosens, this increases the chances of your well becoming contaminated with pesticides, herbicides, or fertilizers from the surrounding landscape. Soil could also get into the well, where it could clog the pump. There are attractive well head covers available that look like rocks or statues, but that are hollow so they fit over the head. Use one of these instead if you don't like the well head's appearance.
#2: Ignoring basic upkeep
The well head and well cap are the part of the well most likely to fail simply because they are above ground and exposed to both weathering and mechanical damage. Check the cap at least once a month to make sure it hasn't become cracked or broken, and also to make sure the seal around the cap is still tight. Any ID tags should also be firmly affixed to the well cap. If you notice damage or if the cap is missing completely, plan to have it replaced as soon as possible. An open well is more likely to become contaminated, which can render your water source unsafe.
#3: Skipping testing and inspections
Although you can monitor the condition of the exposed portion of the well, the well itself can be a bit more tricky to inspect. First and foremost, the water should be tested annually at a minimum, although twice a year is generally better. Even with treatment, some contaminants can remain in the water so you need to make sure the quality is still safe to drink. You should also have the well and well pump inspected once a year. This way you can catch any issues before they become severe. It is much more cost effective to repair a well or pump as opposed to replacing them.
