Tips For Choosing A Submersible Well Pump

Construction & Contractors Blog

If you have a well on your property that supplies your home with water, then you will probably need to replace the well pump at some point. Most well pumps last at least a decade, and you can expect to pay about $1,200 at most for a submersible pump. Since the cost is a bit hefty, you want to make sure that you buy the best pump possible for your property. Keep reading to learn about what you should be looking for.

Diameter Of The Casing

The well on your property will be fitted with something called a well casing. This is the metal pipe that emerges from the top of the well. This is also the space where the pump must be inserted into the well. While most people consider the larger well and its circumference and depth, the well casing diameter is also important if you want to get the pump into the well in the first place.

The pump can be just slightly smaller than the circumference of the casing. There needs to be about one inch of clearance between the pipe and the pump when inserting it so it does not get stuck. The vast majority of well casings are five or six inches. If you have a six inch casing, then a five inch submersible pump is a good idea. 

The most common pumps are four inches wide and work with most casings. These are a good choice, but you may need to go with a much smaller three inch diameter variety if your casing pipe is smaller than five inches. Before you settle on your pump, make sure that you take a clear and distinctive measurement of the casing pipe. Otherwise, you may end up getting the pump stuck and this requires casing removal and replacement.

Gallons Per Minute

If you are replacing your well pump, then you can often look at the pump itself to find the specifics of the device. Metal plates are often located on the pump to help you find an appropriate replacement. However, this is not always the case. If there is no information on the pump, then you may need to do a bit of investigation to determine the strength of the pump you need. 

One of the most important attributes of the well pump is how many gallons per minute the device can pump into your home. To determine the correct GPM, go around your home and count the number of faucets and other fixtures that use water. Every fixture should count as a device that uses one gallon per minutes. For example, if you have 10 fixtures, you want a pump that can pump 10 gallons of water per minute. However, 12 GPM pumps are the most common, so you can opt for one of these instead.

inspecting the roof on your home

When was the last time you really looked at your roof? I had no idea how important yearly inspections of my roof was until I found myself footing the bill for a full roof replacement and interior ceiling replacement. Since then, I have learned how to inspect my own roof twice each year. I always inspect it each spring after the harsh winter elements have gone away and again in the fall before winter weather sets in. You can use the information compiled on my website to inspect the roof on your home and make the small repairs that will save you from full roof replacement.
