"Tried to schedule a routine maintenance appointment available to customers who signed up for service plans, but Len could not follow through with their commitment three failed/rescheduled appointments in a row!! Each required four hour commitments from the customer. I tried to communicate with dispatch and customer service but unfortunately I don’t think these two departments have an open line of communication between them. I would not recommend for anyone to work with or engage with this company. Len did not follow through on their half of the commitment and disrespected my time as an in office working professional."

"I accidentally broke the PVC pipe leading out of the condensation drain coming out of my air conditioning unit. (This may seem to be a minor problem, but that is only because you didn't have to haul the buckets of water produced during this heat spell to the sump pump drain.) I put in the request on Monday afternoon. They arrived first thing Tuesday morning -- early. It took them all of about 15 minutes. I could not ask for better service. They were prompt, professional, friendly, and courteous."

"They charged $98 to come give me an estimate for swapping our a shower valve cartridge, which was fine, but the pricing they provided was completely unreasonable, $1,000. They were unwilling to provide any detail for the price. I ended up buy the part myself for $30 and replaced it in 30 minutes."

"Able Well helped me perform a chemical treatment of my home well after it failed a bacteria test. They also replaced and rewired the well cap. They were knowledgeable about the system and taught me a lot of great info about my home system. The reason for 1-star is the complete lack of punctuality. They were 5 hours late on the first day and 4 hours late on the second date. No one ever reached out to me to let me know they would be late or communicated a need to change the time of the appointment. For how expensive the service was, I would expect better communication and ability to keep an appointment. I'd recommend shocking your well yourself, it isn't hard, and spending almost 10 hours waiting on arrival was a hard way to spend my day."

Septic Tanks questions, answered by experts

A household of four can easily fill a 1,000-gallon septic tank within a week. It may be 10 to 14 days for smaller households. But the reason why you don't need weekly pumping is because the tank's contents eventually reach the overflow pipe. They flow down this pipe to the absorption area whenever water is used in your home. The tank keeps working at this full level until it's pumped again.

The water refills in a well through gravity that draws water from the water table to fill the vertical hole. The pump brings the fresh water through a pressure tank and to the pipes in your house. The well continues to refill indefinitely as long as you don’t use more water than the well is producing.

Pump the tank every 3-5 years, avoid flushing non-degradable items, and address leaks promptly to extend system life.

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.

The main difference between a mound septic system and a conventional one is that the drain field in a mound system is built up into a mound composed of sand and gravel to increase the filtration time the wastewater sees before it is returned to the aquifer. There’s also a significant cost difference, with mound systems typically costing far more than standard septic systems.
