"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

There are a lot of issues that can cause a septic tank to collapse. Those include failing to regularly pump or service it every three to five years, placing too much weight atop the system—by parking your car on top of it or because of a heavy snow buildup for instance—or because of structural damage done by overgrown tree roots.

A septic tank riser should extend to just above the ground level or slightly above it. The exact height can vary depending on local regulations and personal preferences, but a common guideline is to have the riser's top flush with or no more than a few inches above the surrounding ground. This height allows for easy access to the septic tank without creating a tripping hazard or obstructing mowing and landscaping activities. It's essential to ensure that the riser lid is easily visible and accessible for regular maintenance and inspection while being mindful of safety and aesthetics.

The best times of year to empty or pump a septic tank are spring and fall. Many professionals recommend spring because the ground has thawed, making the tank easier to access and the waste less likely to be frozen. Pumping before summer also helps avoid conflicts with vacations or outdoor gatherings. Fall is another great option, as contractors may be less busy, and servicing the tank can reduce the risk of overflow from winter and spring precipitation. While summer is also a suitable time, winter is generally not recommended due to frozen ground.

French drains, sump pumps, and exterior waterproofing systems are common options. Choose one that best suits your property’s needs.

You can cover a septic tank riser with dirt, but it’s not always the best idea. If you have a plastic riser and you bury it, you can easily lose track of it since you won’t be able to find it with a metal detector. Make sure to clearly note where your rise is in your yard so that you’re able to access it easily the next time you or a septic pro needs it. Don’t bury the cover too deep or you could place too much stress on it and make it too difficult to access in the future.
