"The septic tank was pumped satisfactorily. The problem we had was that our gate and latching mechanism were damage by his employee doing the work. We were told that the gate was damaged. We called Mr Andrews after we discovered that gate was damaged. Mr Andrews told me that his employees were independent contractors and were responsible for any damages that occur. Mr Andrews asked me to send him pictures and a description of the damage. He said he would have his independent contractor contact me to resolve the issue. To date we have not heard from his independent contractor or Mr Andrews to resolve the issue The company does a good pumping your septic tank but doesn't take care of any damages that they cause.

"During Freeze-agaddon 2014, Greg was the only one able to guarantee that someone would be out today, and the two guys he sent out were fantastic - easy to work with, very detailed and specific about what they were doing and why, and fixed a major problem thoroughly and quickly. Waking up to a pool of water in the basement due to burst pipes is anything but ideal, but Plumb Tech Services turned a Full On Crisis into a Problem Solved quickly and effectively. They also spent time after the fix going over various ways to prevent it from happening again. Very helpful and informative. If I ever have a plumbing problem of any kind, I will definitely be using them again (though hopefully I won't need to!).

"This would have gone pretty well except that when John (son of Henry) came to look at the job he told me that they would save and replant the bushes and plants that would have be removed to make their initial hole at the curbside city water connection (about 2'x 6' on surface). This was necessary to allow their underground-pipe installer to reach the depth required. When it came to "replacing" the plants, all they did was dig some holes in what was now a clay surface, pick up the plants with what topsoil balls remained around their roots and put them in the holes, doing little else to properly replant them. I have had to get my landscaper out to finish the job. They did do a very nice job of connecting the new copper water line to the house waterline in the basement and cleaned up well. City inspector checked both ends and was satisfied. Bottom line: if this installation had not had to start in our street-side garden, but maybe just in our lawn, I would have been happier with the results."

Septic Tanks FAQs, answered by experts

The septic installation company must follow several steps to put in a new septic system and leach field. The installer will study your property and determine the best place for the tank and leach field. The site should be away from existing structures, be free of trees, and have proper drainage and grading. Preparing the site for the tank and leach field will require significant excavation work.

The best times of year to pump or empty a septic tank are spring and fall. Many professionals recommend spring because the ground has thawed, making the tank easier to access, and any snowmelt or rainfall can aid in proper drainage. Pumping before summer is also ideal to avoid conflicts with vacations or outdoor gatherings.

Fall is another great option, as contractors may be less busy than in the spring. Servicing the tank in late fall or early spring can also reduce the risk of overflow from extra precipitation during winter and spring.

While summer is a possibility, winter is generally not recommended. The ground is often frozen, which can make it difficult to access the tank, and the waste inside may also be frozen.

Yes, it is generally okay to oversize a well pressure tank, and it will not harm your well system. The primary advantage is that a larger tank reduces frequent pump cycling, leading to longer, slower cycles with fewer startups. This can result in less wear and tear, potentially increasing the lifespan of the pump and conserving energy. However, there are drawbacks to consider. Oversized tanks have a higher upfront cost and require more physical space. While not necessarily a bad thing, opting for a tank that is appropriately sized for your well is often the most efficient choice in terms of cost and space.

The smallest septic system available for purchase typically includes a 750-gallon tank. However, the smallest size you can legally install is determined by local regulations, and many areas require a minimum capacity of 1,000 gallons. The cost to install a small septic system generally ranges from $2,910 to $13,900. Before proceeding, it is essential to check with your local health department or consult a local septic professional to confirm the minimum legal requirements in your area.

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.
