Q: Is it better to have 30/50 psi or 40/60 psi for a well pump?

• <div><p>For the most part, choosing between 30/50 psi and 40/60 psi is based on your water-pressure preference. However, it can also depend a little bit on your house&mdash;if you have older plumbing, a lower water pressure can be easier on the pipes (and a bit more gentle on your well pump). </p><p>The lower 30/50 pressure is usually enough for a single-story home, but you may want 40/60 if you have multiple stories, as the extra pressure helps water flow smoothly up to the second floor.</p></div>

Q: How do professionals ensure the quality of well water?

• <div><p>Through testing for pH, bacteria, and contaminants, ensuring safe consumption.</p></div>

Q: How do I determine the right well pump size for my home?

• <div><p>The average three to four-bedroom home typically uses a well pump rated for 8 to 12 gallons per minute (GPM). To find the most accurate size for your specific needs, a common rule of thumb is to count the number of water fixtures and appliances in your home and aim for that number in GPM. This calculation allows for about one gallon of water per minute per fixture. Because estimating the correct size can be challenging, it's best to have a professional technician make the final determination. A professional can ensure your pump provides sufficient water for your home, especially during peak usage hours.</p></div>

Q: Will a larger pressure tank increase water pressure?

• <div><p>No, a larger well pressure tank will not increase your home's water pressure by itself. Water pressure is determined by the pressure control switch on the well pump.</p><p>However, a larger tank does offer other benefits. It can store more water, which allows you to run water for longer periods before the pump needs to turn on. This reduces how often the pump cycles on and off, leading to less wear and tear on the pump and the entire well system. Consequently, a larger tank can help extend the life of your equipment and may prevent future pump issues that could affect water pressure.</p><p>If your goal is to increase water pressure, consider these alternatives:</p><ul><li><p>Adjust the pressure settings on your tank to a higher PSI (pounds per square inch).</p></li><li><p>Replace your current pump with a model that has a higher flow rate, measured in gallons per minute (GPM).</p></li><li><p>Have a professional install a water pressure booster pump in your plumbing system.</p></li><li><p>If you experience pressure fluctuations, consider upgrading to a constant pressure system.</p></li></ul></div>

Q: How do you tell if an irrigation pump is burned out?

• <div><p>There are many signs to look for that will tell you when your irrigation pump is burned out. This may include low water pressure, sprinklers that sputter a lot before turning on, discolored or dirty water, or a pump that stops working altogether. If your pump has any of these issues, it is probably time to replace it.</p></div>

"Two service Techs, Daniel and Kevin, came by the same day i called regarding a clogged sewer line. They were very pleasant and personable which put me immediately at ease. They performed an inspection and showed me a live video feed of my sewer line, indicating where the roots were growing in that caused the clogging.
They recommended hydrojetting due to the size of sewer, and scheduled a visit the following day. The next day the same techs came by and cleaned out the sewer line via hydrojetting. Afterwards they did another video inspection and showed me their results. They were professional, communicative, clean, and very pleasant to deal with.

Have a professional install a water pressure booster pump in your plumbing system.
