"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."

About Us: We are locally owned/operated professionals providing dependable service. Able Well & Pump Service (AWPS) (formerly Artesian Well & Pump Service) has A Cell Number Also At 410 458 7171

"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."

"Woke up this morning to my hvac leaking and contacted Markool. I have never used them before and was in a pinch. They fit me right in this morning and were out at my house within 2 hours. The tech stepped in the door and placed covers for his shoes so he did not track in any dirt which was impressive! The tech was very professional and super friendly. Problem was diagnosed and FIXED within an hour. The price was extremely reasonable to the point I was shocked in a good way (expecting a higher price). Anyways, I will most certainly be a returning customer. Thank you Markool Heating Cooling Plumbing."

"Installation was solid. The labor price was a bit high. The main concern was the materials markup. The picked up a shower stem from Lowes. Those are normally about $50. The tech said that the stem wasn't $120 but they charge them extra when they use their contractor code. That seemed weird since normally get discounts since they purchase a lot. I should have questioned it but it didn't register to me until after he had left."

"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."

Septic Tanks questions, answered by experts

There are many potential causes of low well water pressure. The most common include sediment buildup, leaking pipes, a failing well pump, or a cracked pressure tank. 

Wells vary widely when it comes to lifespan, and there isn’t a way to exactly predict how long a well may last. Some wells can last well beyond 100 years, but they more commonly last between 25 and 50 years. Performing regular maintenance, such as replacing worn valves, can help prolong the life of your well.

The depth of your septic tank has nothing to do with its size. In fact, some septic tanks can even be installed above-ground! Like other sizes, a 1,000-gallon septic tank could be buried as shallow as 4 inches below the ground or as deep as 4 feet. It all depends on your specific property.

Cisterns can be used as septic tanks, but septic tanks can’t be used as cisterns. This is because cisterns need to meet FDA standards for drinking water, but septic tanks aren’t required to meet those standards since they are only used for wastewater.

A well does not run out of water because the groundwater continues to refill with rainwater that seeps through the ground. If the well is too shallow or there is a drought, a well can run dry or be short in supply. It’s important to have a well deep enough to source enough water for your home’s use. Deeper wells tap into more groundwater reserves. If your well is not producing enough water, you may need to redig your well.
