"Great experience Justin, Nate & Timothy were awesome. Very knowledgeable, professional & curious. Aside from the cleanliness they delivered an experience. I highly recommend HL bowman if you want rapid service on your HVAC. Pricing was reasonable in my opinion & financing is an option. Keep in mind when seeking quotes for your HVAC repair/ new install you must consider performance over equipment, that is if your want a good system that will have a good run/life span."

"Matt, AJ, Scott, Vinnie, Charlie all did a terrific job. They installed a gas water heater, installed a shut off on the water heater where there was one missing, replaced a kitchen sink from an old double sink to a new full size sink and in doing so, moved the garbage disposal and re-piped the whole project. They checked other pipes & plumbing and repaired a broken outside water pipe. Tisha in the office was also wonderful - very accommodating, congenial and they are all very customer service oriented. Respectful, honest, and I would highly recommend this company to anyone."

"Jason was prompt and helpful and was very flexible in changing or modifying the nature of some of the work before starting. He did virtually all the grading himself and knew exactly what to do. The work was done on time and as specified. I will surely contact him if I need drainage work for another project."

"Devon did an excellent job draining my septic tank, excavating to hook up to city sewer, crushing and filling in the septic tank. Made sure that I was hooked up before they left the first day. Very fair pricing. Highly recommend!"

Septic Tanks FAQs, answered by experts

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.

Expect to take at least a day to drill your own well by hand. For a 500-foot well, this could take even longer, depending on the makeup of the soil and the terrain you are drilling through. Other factors include your physical strength and overall fitness level and the weather conditions you’re working in.

Yes! Toilet paper can be flushed if you use a septic tank. While unique toilet papers designed to be used with septic tanks are available, many people have no problem flushing regular toilet paper with a septic tank, so long as you don’t flush too much toilet paper all at once. Do not flush any type of baby wipes or bathroom wipes, even if they say “flushable.”

There are a couple of ways you can determine the depth of your well. One method is to use a device called a well sounder. This tool has a long measuring tape containing a sensor to alert you once the end reaches the water. 

Or you can DIY it by using a long tape measure with a half-filled bottle of water attached to it. Lower the tape measure into your well. Once you feel tension on the tape, you’ll know the bottle has reached your static water level. This will give you an approximate idea of your well’s depth.

Several warning signs can indicate current or future issues with your well pressure tank. If you notice inconsistent water pressure, water spitting from your faucets, clicking sounds, or electricity bill spikes without other obvious causes, it may be time to get your pressure tank and well system looked at by a professional.
