Q: Does rainwater go into my well?

• <div><p>Rainwater doesn't have a direct impact on the amount of water in your well. Instead, the majority of rain runs off into other bodies of water such as streams, rivers, and lakes. These bodies of water may sometimes function as the area&rsquo;s reservoir and create aquifers, which then help to replenish your well.</p></div>

Q: How do you tell if your drain field is failing?

• <div><p>There are a few signs that indicate a failing drain field. For instance, if your septic tank starts requiring more pumping than normal, your drain field might be failing. Other signs to watch for include poor drainage after rain, standing water or sewage over the septic system, a strong septic smell outside, new and healthy grass growing over the drain field, and plumbing backups in your sinks, bathtubs, or toilets. </p></div>

Q: What psi should a well pressure tank be set at?

• <div><p>The pressure in a well pressure tank should be set 2 to 3 PSI below the pump's cut-on pressure. The cut-on pressure is the lower number in the pressure setting (e.g., the '30' in 30/50 PSI) and is the point at which the pump starts. The cut-out pressure is the higher number, where the pump stops.</p><p>For example:</p><ul><li><p>If your pressure switch is set to 30/50 PSI, the tank pressure should be 27-28 PSI.</p></li><li><p>If your pressure switch is set to 40/60 PSI, the tank pressure should be 38 PSI.</p></li></ul><p>Common pressure settings for household applications include 20/40, 30/50, and 40/60 PSI. The difference between the cut-on and cut-out pressure is typically 20 PSI.</p></div>

Q: How long does it take a well to replenish water?

• <div><p>Wells typically replenish at a rate of about five gallons per minute, but several variables can influence how quickly they refill. A deep well will take more time to replenish than a shallow one. The replenishment rate can be slowed by issues such as leaks, damage, a faulty well pump, or a clogged well screen. Other factors, such as the surrounding geology, regular precipitation, and proper maintenance, also affect the recovery rate.</p></div>

Q: Can you put water softener backwash into a septic tank?

• <div><p>While you can drain water softener backwash into a septic tank, doing so may cause several problems. One problem is that increased sodium chloride levels from water softener backwash can kill septic tank bacteria, decreasing the effectiveness of this wastewater treatment system. Another issue is that large calcium deposits can eventually stop up the drain field and lead to poor drainage. </p></div>

Lamar is amazing! Not only did he do excavating for our new house build, but he also installed our new septic. He did such a good job that even the inspector said it was one of the nicest installs he has seen. Highly recommend!

He did a thorough job to make sure every thing was out of the tank. Much better than others in the past. He also started right away on digging out the old access cover even though he didn't have the new cover with him. He came back 2 days later and completed the job. Looks great when he got done.
