"The technician emptied the freezer, which was in the basement, to work on the part that needed repair. Then he neglected to put anything back into the freezer, including a turkey I had bought for Christmas and a rack of ribs. Two days after he left, I went out of town for two weeks. The turkey actually exploded and spewed its liquid all over everything, which had to be discarded. I let AHS know and they couldn't even bother to call me or follow up on this. I'm considering not renewing my contract with them because of the quality (or lack thereof) of many of the providers they send."

Septic Tanks questions, answered by experts

The purpose of a septic tank is to allow solid wastes to separate out of the wastewater using time, gravity, and other natural biological processes. If your septic tank is too small, it might be overwhelmed by solid waste and unable to accomplish this task—and if it’s far too large, there won’t be enough liquid in the tank to nurture the necessary bacteria to aid in the breakdown process.

Buying a well drilling kit will save you money over hiring a professional. That said, digging a well is risky. If you make an error, you may have to get help fixing it. Also, the DIY costs are still pretty hefty when considering everything needed to complete the project successfully. You’ll need to account for the permit, pump, water tank, and more. If you don’t feel comfortable taking the necessary precautions to tackle this on your own, go with a pro.

Concrete septic tank risers are heavier and more durable than plastic or fiberglass ones, making them suitable for long-term use. Installing a concrete riser differs from installing plastic or fiberglass risers primarily in the materials and methods used. The process involves cutting the concrete risers to the required length and then stacking them, using concrete sealant or adhesive between sections for secure attachment. Due to their weight, extra care is necessary during leveling and the attachment of sections. Concrete sealant or adhesive may also require a curing before the riser is ready for use.

If you notice a septic smell in the house, you can either call a septic system repair company or a plumber. These professionals have the proper licenses and equipment to investigate the pipes and septic tank while keeping your family safe from sewage gas exposure and raw sewage leaks. They will be able to find the problem as soon as possible and get it fixed so that your home can get back to smelling fresh again.

Call a dedicated well and pump professional to install your new well pump. In some cases, plumbers may have the experience needed for the installation, but it’s always better to go with a specialized pro. Well and pump contractors have hundreds of hours of experience with all different types of wells and pumps.
