"Ultimately happy with the end result and fair price for our 30ft sewer lateral replacement. Miguel was professional, friendly, and hardworking. However, communication was a bit spotty and we had follow up many times (I understand this is the busy season, though). Also, it was unclear if we were supposed to call 811; we assumed he would, but didn't, and this was an issue as the water line was hit during construction and the city had to come to shut it off on the whole street. It was handled quickly, but would have been avoidable. The project ended up taking much more time than expected, but it was completed in a day, as promised. I would recommend him, but you should be diligent and responsible yourself to make sure all the right steps are being taken."

"I cannot say enough about how good this experience with John Mountain/Mountain Engineering has been. They said it would be 3 weeks; anti was. The work was painstakingly done, including a French drain behind the wall. And they replaced the plants that were destroyed during the process, which was an unexpected bonus."

"Leo went out of his way to meet my concerns about cost, collaboration with my neighbor, and how the fence would look. He submitted multiple bids giving me options as to how to do it and at what cost. He tailored his approach to my needs. His team was easy to work with. The team worked quickly, efficiently, and throughly. The fence looks great!"

"We could not be happier with our new bathroom, thanks to McCormick! Khaled was knowledgeable and really took the time to understand our style preferences. The whole team was great about keeping the workspace tidy, which we appreciated. Now, we have a bathroom that feels luxurious and welcoming. Highly satisfied with their work!"

Septic Tanks questions, answered by experts

Most professionals recommend that a deep well pump shouldn’t run more than 10 hours consecutively before cycling off. Overworking the well pump beyond the recommended amount can prematurely wear out your pump and burn out the motor, which means replacing it more often than you otherwise should need to. Your well pump should also come with the manufacturer’s use and maintenance recommendations that are specific to the model.

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.

Ideally, you should conduct a mechanical inspection and a bacterial or well water inspection yearly. While you might be able to push it off to every other year, it’s best to have peace of mind, especially when it comes to something that you use so frequently. 

If you experience repeated gastrointestinal illness in the household, it's important to test the well water more regularly for quality and cleanliness to check for bacteria.

You should pump your septic tank once every two to four years for a family of four, depending on your septic tank size. You should pump a 1,000-gallon septic tank every two years, while a 1,500-gallon tank should be pumped every four years. Water usage also affects how often you should pump your septic tank. If you notice slow drains, foul smells, or gurgling sounds from your drains, you should pump your septic tank as soon as possible.

You can find your septic tank using a few different methods. For one, you can check your property records at your local municipal office. You can also inspect your yard looking for a depression, a septic tank lid, or lush septic-area vegetation which would indicate a leach field. You can also follow your pipes from the home to the yard. If you can't find your septic tank on your own, a local septic pro can help.
